Welcome

Congratulations on your purchase of the new S CLASS™ cutter!

The S CLASS™ cutters are made for sign-makers who demand the very best in cut quality.

Unrivalled tracking delivers guaranteed accuracy on cuts up to 12 meters (40 feet) long. So
you won't have to monitor your cuts, even when you're sending the long jobs through.

The S CLASS™ T cutters with genuine tangential operation, and not simply "tangential
emulation," handle a wider range of materials and cut with unparalleled precision.

OPOS-CAM, using intelligent camera optics and camera control software, has been uniquely
designed to meet the demanding needs of wide format graphics companies and inkjet
printer manufacturers. The new camera upgrade option has been added to significantly
increase speed and media options.

In short, the S CLASS™ cutters take cutting signs to a new level.

This manual is a reference guide for installing and operating the S CLASS™ cutter models.

1.1 Unpacking the Cutter

NOTE: Save the shipping box and any other packaging items in case the cutter needs to be

shipped. Do not ship the cutter without first completely repacking it in its original
packaging.

Before unpacking the cutter, make sure that there is enough space to assemble the stand
and to set the cutter aside to insert the stand screws.

CAUTION: For safety reasons, no fewer than two people should be involved in unpacking
the cutter.

1.1.1 Removing the packaging from the cutter

1. Remove the straps and the staples and open the lid of the box.

2. The cutter is packed in foil and sits in front of the box. Behind the cutter is the box

containing the stand. The accessories are located at the bottom in a separate box.
Check first whether everything is present.

3. Do not throw away the packaging. Shipping it without the original box voids any

warranty.

8. Make sure the linen basket is guided under the horizontal panel. Take the last large c-

shaped tube and feed it through the rear hem in the linen basket. Then put the tube on

the two rear tubes that stick out of the feet. Make sure the holes are oriented right-side
up so that the tube clicks securely on the tubes. The finished stand should look like the
stand in the picture below (Figure 1-8).

9. The right leg has a hole in the foot and a cutout in the leg to guide the power cable and

data cable. If you plan to use these cable guides, then put the cables in place before

mounting the cutter on the stand.

1.1.3 Mounting the cutter on the stand

1. Carefully take the cutter out of the box and lay it on its back (first spread out the

cardboard of the stand box, and then rest the cutter on that cardboard). Then insert left

and right two screws and turn them 3 turns in. Do not put a screw in at the front.

1.2 Cutter Components

1.2.1 The Cutter as viewed from the front

FIG 1-10

1-10 S CLASS™ CUTTER, FRONT VIEW

1. Pinch rollers: The pinch rollers clamp the media to the drive system to ensure accurate

tracking. The cutter has two extra pinch rollers to ensure that wide media stays flat in

the middle. The outer drive pinch rollers have a selectable pressure; the extra rollers in

the middle can be enabled or disabled.

2. Touch panel: All cutter activity can be initiated from the 320x240 dot touch panel. The

panel displays information about the cutter’s current status and/or actions that need to

be taken.

3. Pinch roller lever: This lever is used to raise and lower the pinch rollers for media

loading.

4. Media drive sleeves: The media drive sleeves move the media only when the pinch

rollers are in the “down” position. The following table lists the number of sleeves

installed on each model of the cutters.

Number of sleeves S75 T S140 T S160 T

Short sleeve 4 8 9

Long sleeve 1 1 1

Setup 1-6

5. Tool carriage: The tool carriage is the mount for the knife holder, pen or pouncing tool.

It has also holds the camera and a cut-off knife to cut a sheet from the roll when a job is

finished.

6. Cutting strip: A self-healing orange strip helps avoid any damage to the knife tip when

no media has been loaded. Since cutting is done on the cutting strip, it is essential that

the strip remains intact.

7. Pouncing strip: An extra black strip to pounce on.

8. Tool holder: The left end cap has a rim so it can be used for tool storage.

9. Screws to secure the cutter base: Make sure all three screws are secured at each side

before the cutter is used.

10. Media basket: The stand and linen media basket come standard with all cutters.

1.2.2 The Cutter as viewed from the back

FIG 1-11

1-11 S CLASS™ CUTTER, REAR VIEW

1. Pinch rollers: The pinch rollers clamp the media to the drive system to ensure accurate

tracking. The cutter has two extra pinch rollers to ensure that wide media stays flat in

the middle. The outer drive pinch rollers have a selectable pressure; the extra rollers in

the middle can be enabled or disabled. Do not move the pinch roller assemblies while

holding them from this side only.

2. Pinch roller lever: This lever is used to raise and lower the pinch rollers for media

loading.

3. The fuse box: The fuse is located at the right side of the power entry module. Check the

specification section to see which fuse is used in the cutter.

CAUTION: For continued protection against risk of fire, replace only with the same type and

rating of fuse.

4. Power On/Off switch: This rocker switch, in the middle of the power entry module, sets

the cutter’s power to ON or OFF. To switch on the power, press the “I” side of the rocker

switch. To switch off the power, press the “O” side of the rocker switch.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-8

5. AC power cord receptacle: It is located at the left-hand side of the power entry

module. The power-up procedure is explained in detail in Section 1.3. Always use a

power cord that was delivered with your cutter.

6. USB port: This interface is based on the standards specified in Universal Serial Bus

Specifications Revision 1.1. It allows a high-speed bi-directional communication

between the host computer and the cutter.

7. RS-232 port: This DB-9P connector provides serial bi-directional communication

between the cutter and a host computer. If the cutter is connected to the computer

with this connection only, then the camera option does not function.

8. Screws to secure the cutter base: Screws (3 left and 3 right) hold the cutter base to its

stand. All the screws must be properly tightened before using the cutter.

9. Tubes for media basket: Tubes in the back and front hold the media basket. They can

easily pulled outwards to put the basket in its place.

10. Casters: The casters on the stand are equipped with locking brakes. Once the cutter has

been moved to its new location, press the brakes with your foot to lock the casters.

11. Media basket: The stand and linen media basket come as standard equipment with all

cutters.

12. Roll media guide bushes: The two flange guides serve to keep the media roll in place

when media is pulled from the roll.

13. Media support rollers: Rotating support rollers for the media roll.

CAUTION: An insulated ground conductor must be installed as part of the branch circuit that
supplies power to the wall outlet to which the cutter is connected. The ground conductor
must have the same size, insulation material and thickness as the grounded and ungrounded
branch circuit supply conductors, but the insulating seat should be green or green with
yellow striping.

The ground conductor described above must be grounded at the electrical distribution
board or, if power is supplied by a separate system, at the power supply transformer/motor
generator set.

The wall sockets into which the cutter is plugged must be of the grounded type. The
grounded conductors serving the wall socket must be properly connected to the ground.

For emergency access, the cutter should be installed near the socket-outlet for easy access.

1.4 Connecting the Cutter to a Computer

The cutters support bi-directional USB and RS-232 connectivity. When both ports are
connected at the same time, the port that receives data first will remain active and the other
port will be deactivated.
The camera option functions only when the cutter is connected through USB.

1.4.1 USB connection

The USB cable should be 5 meters (16 feet) or less in length. The connector on the cutter
side of the cable should be USB series B 4-pin. The connector on the computer side of the
cable should be USB A 4-pin.

NOTE: The use of HUB’s or active extensions is not allowed.

The computer has to install three devices. A USB hub, the USB device driver for the cutter
and the USB device driver for the camera.

The installation of the cutter driver and the camera driver must be prepared by a

running a program prior to connecting the cutter to the computer.

The installation of the driver for the hub will be a quiet installation (the user will not have to
intervene).

1. Power off the cutter.

2. Insert the S CLASS™ CD into the computer’s CD-ROM drive.

3. Let autoplay run autostart.

4. Choose language and click on install USB driver. Wait for the driver to install.

5. Click on “install USB driver camera”. Wait for the program to finish.

6. Connect one end of the USB cable to a USB port on the computer.

7. Connect the other end of the USB cable to the USB port on the back of the cutter.

8. Power on the cutter (see section 1.3.3) and return to the computer.

The Found New Hardware Wizard should appear on the computer screen and install the
USB driver.

9. Click “OK” and follow the instructions provided by the Wizard.

10. Restart the computer.

NOTE: When connecting a cutter to a computer for the first time using the USB cable, the

computer will detect the cutter and install the USB driver if the setup program was run. If the
setup program was not run prior to connection, then install the program while cutter is
connected and switched on. After that the program is run, the computer will detect a new
device and install the correct driver automatically.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-12

NOTE: It is recommended to use always the latest version of the driver. The Cd is made so

that it downloads the latest version automatically. If no internet connection is available, then
it is possible that the driver on the CD is outdated.

NOTE: When installing a cutter on Windows Vista or Windows 7, then make sure that the
user has administrative rights and that UAC is deactivated.

1.4.1 Check for interfering programs or hardware

Interference results in ‘green lines’ ( when Camera control is started and when it is set in
color mode – see section 3.6):

The cause of this can either be software or hardware related.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-13

Other programs could interfere with the camera, it is recommended to check if such
programs are running. The procedure to check this is simple.
Double click on the ‘Safely Remove Hardware’ icon in the tray. Choose to stop the videology
device.

If the computer allows it, then disconnect and connect cutter again.
If the computer does not allow it, then check which program or service prevents this
(usually chat programs similar to windows messenger).

NOTE: power saving programs can also interfere with the proper working of the camera and

driver. For non-laptop computers set power options to high performance. For laptops make
sure that the power suspend setting for USB is disabled.

Hardware causes could be devices that are USB connected and that generate too much
traffic on the USB bus.
Examples are external hard disk, camera’s, USB adapters,…
Just disconnect each device separately and check if the lines disappears.

NOTE: Make sure the cutter is connected and switched on before camera control is started.

Also make sure that no other cutting software is running before camera control is started.

NOTE: Close camera control before cutter is switched off.

Setup 1-14

1.4.1.1 RS-232 Connection

NOTE: If the cutter is connected to the computer with serial connection only, then the

camera option will not work. The camera option needs a USB connection.
It is possible to send cut data through the serial port in combination with using the camera
option if the cutter is connected with the computer with both serial and USB cable.

The RS-232 cable should be 5 meters (16 feet) or less in length. The connectors on both
sides are DB-9S type connectors. There is no need to install a device driver when connecting
a cutter with an RS-232 connection.
The parameters of the RS-232 connection must be set in either the properties of the COM
port in the device manager or in the cutting software program itself. Please refer to the
manual for the cutting software on how to set the parameters for the RS-232 connection
with the cutter (see section 4.3.1.5).

1.5 Loading Media

The following procedures apply mainly to the use of roll media. If sheets are used, then
there are two options:
For long sheets, roll up the sheet so that the alignment is identical to that of a roll.
For short sheets, the alignment is not so important. If the sheet is cut off perpendicularly, it
can be aligned to the front border.

1.5.1 Pinch roller positioning

Proper movement of the media will only occur if the media is driven by the two outer pinch
rollers that are correctly located over two drive sleeves.

The pinch rollers are lowered or raised simultaneously by means of the pinch roller lever
arm located on the right-hand side of the cutter. The pinch rollers must be lifted to allow
media loading, during which the media is fed from the rear of the cutter to the front. When
raised, the pinch rollers can be moved manually to the left or the right along the pinch roller
shaft.

CAUTION: Always make sure that the pinch rollers are fully raised before sliding them to
the left or right.
Always hold the assembly at the side of the pinch roller to move it from left to right; do not
reposition pinch roller by holding the assembly at the rear of the machine.

The pinch rollers MUST be positioned correctly and lowered onto the media before an
automatic load sequence is initiated. Make sure that all the pinch rollers are positioned
above a drive sleeve. The outer left pinch roller should be positioned in one of the detents
(click position), just under a white triangular label. The outer right pinch roller should be
positioned somewhere over the long drive sleeve, click positions are located at the edges of
the sleeve (area marked with a white triangular label). The middle pinch rollers should
divide the media in more or less equal parts, but always above a sleeve.

FIG 1-15

1-15 POSITION PINCH ROLLERS

ATTENTION: Always leave the pinch rollers in the “up” position when the cutter is not in
use. Leaving the pinch rollers in the “down” position for a long time will result in a flat spot
in the pinch rollers, which will seriously [negatively] affect tracking performance and
cutting quality.

NOTE: When the pinch rollers are raised during a job, then the cutter will immediately stop
and after one second move the carriage to the right side.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-16

1.5.2 Pinch roller pressure setting

The cutters are equipped with selectable pinch wheel pressure. The pressure can be set to
“standard” or “low.” The pressure should be changed with the pinch rollers in the “down”
position.
When reduced pressure is needed, then it is advised to set autoload to ‘ASK’. Then the
cutter will not start to load the vinyl when the pinch rollers are set down or when it is
switched on. On the touch screen there will be a message, giving the user time to change
the pressure on the pinch rollers.

NOTE: Each time the pinch rollers are raised, the pressure is automatically set back to full
pressure.

FIG 1-16

1-16 REDUCING PRESSURE

To work with reduced pressure do the following:

1. Set AUTOLOAD to ASK (see section on Autoload:).

2. Load media in the cutter (see section on Media load procedure).

3. Push the lever of the two outer pinch rollers upwards and inwards (toward the

machine) – see figure above.

2. Loosen the knobs on the two media flanges. The following illustration shows a loosened

flange (1) and a tightened flange (2).

FIG 1-18

1-18 MEDIA FLANGES

3. Insert a loosened flange into one end of the media roll and tighten the knob. Verify that

the flange is secure. Then do the same on the other side of the roll.

4. Place the flange-equipped roll on the media supply rollers. Set the flanges inside the

groove of the flange guide. The flange guides can be moved laterally on the roller.

FIG 1-20

1-20 FEEDING ROLL MEDIA WITHOUT USING MEDIA FLANGES

5. Start feeding the media from the rear of the machine. Pass the media underneath the

pinch rollers towards the front of the machine.

6. Position the left media edge on the left-most drive sleeve and check whether the

right
media edge is positioned over the long drive sleeve. Then position the left and right
pinch rollers.

The pinch rollers should be positioned over the drive sleeves about 3 to 15 mm (0.1” to

0.6”) away from the media’s outer edges (1). Then pull on the media while holding the
flange at the back so the media is tight. Make sure the front media sensor is covered (2).

FIG 1-21

1-21 MEDIA POSITION

In circumstances where the above procedure does not work, because the media is too
narrow to reach the long drive sleeve, try positioning the left media edge over the
second left drive sleeve and position the right media edge somewhere over the long
drive sleeve. Continue moving the left pinch roller toward the long drive sleeve until
both pinch rollers are in their designated position and directly over the edges of the
vinyl.

In all cases, both edges of the media must cover a drive sleeve. If this is not the case,
reposition the roll of material to cover the drive sleeve.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-19

7. Make sure that the media follows a straight path from the roll of material. To accomplish

this, slide the media roll and flange guides from the left to the right along the media
support rollers.

WARNING

KEEP FINGERS AND OTHER BODY PARTS AWAY FROM THE CUTTING AREA. THERE

ARE HAZARDOUS MOVING PARTS.

8. Lower the pinch roller lever to press the media firmly against the drive sleeves. After

one second the tool carriage automatically moves from the right to the left to sense the
usable media width.

1.5.4 Media load procedure

CAUTION: Do not place any objects in front of, or behind, the cutter that could interfere with

cutter operation. Make sure the media is free to move forward and back. Keep hands, hair,
clothing and jewelry away from moving parts.

While the cutter is on, it will automatically start executing a minimal loading procedure as
soon as the pinch rollers are lowered. The load procedure will also start when the cutter is
switched on while media is already in the machine and the pinch rollers are in the “down”
position (this is not recommended). Always keep the pinch rollers in the up position while
the cutter is not being used.

The minimal loading procedure consists of:

 A media width measurement.
 Media is unwound over a length equal to the width measured between the outer

two pinch rollers.

 A simultaneous 45° axial move of the drive drum (sleeves) and cutting head.

After that, the cutter is ready to receive files from the computer.
When receiving a job from the computer, the cutter will automatically pull the required
media from the roll. It does this in steps and the length of the vinyl used is equal to a
number of times the measured width of the media.

NOTE: It is recommended to change the origin if the camera option will be used to contour
cut. If so, then change the origin so that the knife tip is above the first marker

IMPORTANT: Tracking of longer signs is only guaranteed when the full load procedure is
performed!

1.6 Tool Installation

SAFETY WARNING: The cutters use razor-sharp knives. To avoid serious injury, use caution

when installing, removing or otherwise handling the knife!

1.6.1 Tangential knife installation

A knife has been pre-installed in your cutter. For safety reasons, the knife depth has been
set to zero. Simply turn out the knife (see fig FIG 1-23) to start cutting. Below is the complete
description of how to remove or install a knife.

NOTE: To benefit fully from the advantages of the tangential knife, the amount the knife
extends is very important. The knife pressure may not control the knife depth; the two
rollers of the nosepiece should always touch the media, thus controlling the knife depth.

 Removing the tangential knife

1. Turn the knife holder counterclockwise. The holder will rise up, eventually making it

possible to lift the knife holder out of the tangential head. Underneath is the nosepiece.
Remove this part if another tool will be used in the cutter.

FIG 1-23

1-23 REMOVING THE TANGENTIAL KNIFE HOLDER

2. The knife can be removed from the knife holder by using something like a flat

screwdriver to pry between the knife and the knife holder in the groove.

1-28 KNIFE PRESSURE TEST PATTERN

Peel out the rectangle and inspect the backing.

The knife depth is set correctly when the test pattern cuts through the vinyl completely, the
vinyl is removed, and the blade tip visibly scratched the front side of the media backing. The
blade should never cut through the backing; just slightly scratch the silicon coating and first
few fibers of the backing material.

S CLASS™ with OPOS-CAM User’s Manual

Setup 1-27

NOTE: The knife pressure can also be used to check the knife depth (which is controlled by

the amount the knife extends outs of the nosepiece). If the correct knife pressure is raised
by 150 gr, then the knife may not cut through the backing of the vinyl. If it does, then the
knife depth needs to be reduced.

CAUTION: After setting the cutting depth and/or the knife pressure, perform a thorough

visual check of the knife blade, which can be seen protruding from the knife holder, and
test cutting results on a scrap of vinyl media.

WARNING: Do not operate the cutter if the knife blade cuts through the media backing, as
this will seriously damage the cutter's rubber cutting strip and the knife.

CAUTION: For most vinyl cutting operations, the knife blade tip will be barely visible at the
bottom of the knife tool. If the knife blade tip is clearly visible, then the knife depth must be
re-adjusted.

To prevent damage to the cutter, check the depth of the knife blade tip and the quality of
the cut each time you load a different type of vinyl into the cutter.

Online and pause are two important concepts when using the cutters. The cutter is online
only when the status of the touch screen is similar to figure 2-3.

FIG 2-3

2-3 ONLINE STATUS SCREEN

When online, the cutter can be addressed by the host computer, which means that the
cutter will execute cutting or plotting instructions issued by the host computer's application
software. As soon as any other button on the cutter is pressed, the cutter pauses and can no
longer be addressed by the host computer. However if the computer was busy sending
cutting data to the cutter it will be able to do so until the buffer of the cutter is full.

If the pause button is pressed, then the tool can be moved around the working area with
arrow buttons.

Press

to raise or lower the tool (once push toggles the status each time).

Press to set the cutter online again.

2.1.4 Actions

The “Actions” button is used to move the origin (start point for cutting), initiate a load
sequence, abort the cut in progress, or recut the last file.
When the action button is pressed during a job, then the job will halt immidiatelly

 The “Set origin” instruction is used to move the knife origin.
 The “Load” instruction is used to initiate a load sequence.
 The “Reset” instruction performs a complete reset of the cutter.
 The “Media alignment” instruction is used to initiate registration of the OPOS markers

just before a contour cut is begun.

 The “Recut” instruction recuts the last file sent to the cutter (provided that it fits in the

cutter’s memory (buffer).

 The “Cut off” instruction is used to cut of a job done and to reset media origin.

2.1.5 How to Set Tool Parameters

The cutter can work with a knife, pen or pouncer. There is the choice between drag knife
and tangential knife.
Once a tool has been changed, then the tool parameters (menu settings) must be reset or
checked.
All the different tools have one parameter name in common: the pressure.
Each tool has also its specific parameters.
Tool parameters can be changed by either changing them in the current user, or simply by
changing user (see section 2.3).

NOTE: The S CLASS™ cutters will only perform according to specifications if a genuine
Summa knife, pen or pouncing tool is installed. Do not replace the standard knife, pen or
pouncing tool with products from other manufacturers.

Each keystroke can initiate an internal test or movement of head or media.

2.1.8 Calibrating a tangential knife

The purpose of the knife calibration routine is to detect and, if necessary, to correct
problems related to the concentricity of the tangential knife blade.

NOTE: Knife calibration should be done each time the knife is changed and should be
checked if the knife shows signs of wear.

Knife calibration errors may be due to any of the following causes:

• Origin deviation

. The knife tip is slightly rotated in relation to its theoretical 0° angle.

This error can be corrected by adjusting the origin.

• Lateral deviation. The knife tip deviates from its theoretical center in the lateral
direction. This error can be corrected by adjusting the lateral parameter.

• Longitudinal misalignment. The knife tip deviates from its theoretical center in the
longitudinal direction. This error can be corrected by adjusting the longitudinal
parameter.

vinyl.
The fan shaped pattern 3 should have a clear cut line in the middle; the ones at the sides
show burs.
The squares in 4 should be aligned and equal in size.
The 4 vertical cuts in 5 should be clear without any burs and straight all the way from top
to bottom (not rounded near the horizontal lines).

NOTE: It is possible that not all test patterns come out perfect (depends on the type of
vinyl). Test pattern 1 and 4 are the most important test patterns. They should be as close to
perfect as possible.
Start with the setting of the origin, then set the other parameters

Origin correction

If the clear cut line in test pattern 3 is to the right, then increase the value of the origin,
begin in steps of 20, and lower the steps when nearing the correct origin setting.
It helps sometimes to gently feel the pattern to find out which side has the clear-cut line.
If the clear cut line in test pattern 3 is to the left, then decrease the value of the origin,
begin in steps of 20, and lower the steps when nearing the correct origin setting.

NOTE: Failing to set the knife parameters correctly will result in poor cut quality.

2.1.9 Changing drag knife offset

A very important parameter for a drag knife is the offset. The offset is the distance between
the knife center and the knife tip.

NOTE: Knife offset should be set each time the knife is changed and should be checked if
the knife shows signs of wear.

Typical knife offset for Summa knives is between 0.41 and 0.45 for standard knives, and
between 0.9 and 0.97 for sandblast knives.

NOTE: Sandblast knives should be used when the material that needs to be cut is thicker
than 0.25mm.

2.2 How to Set Cutting Speed

The actual speed at which the tool moves is determined by 4 different parameters. Speed
(and acceleration) while the tool is down; speed (and acceleration) while tool is up.
These 4 parameters have been bundled in one parameter to make changing speed fast and
easy.
This overall parameter is called “velocity” and is the speed the cutter uses when the tool is
down. If velocity is raised or lowered, then the other parameters are also raised or lowered
accordingly.

There is one fixed speed: the speed at which the cutter pulls the media from the roll. This
speed is fixed at 200mm/s (8ips).

Setting the cutting speed:

1. Power on the cutter.

2. Press .

The main menu will appear on the screen.

3. Press .

The velocity will appear on screen.

NOTE:. Sometimes the cutter feeds the material too fast and the media has no time to
settle and fold into the basket. A fifth speed parameter is designed for such cases. The
speed of long X axis vectors is reduced automatically so that the media does not bulge.

8. Press .

The chosen parameter will appear on screen.

2.4 How to Make Sure the Sign Has the Correct Size

(Length Calibration)

The cutters are friction-feed machines. This means that the cutting length is dependent on
the thickness of the material.

The cutters have been calibrated in the factory for standard 2-mil cast or 3-mil calendared
vinyl. Each user (a total of 8) can hold a different calibration factor.
This is very helpful for multi-colored signs; it ensures that the parts in different colors match
up, even if different types of vinyl media are used.

NOTE: For standard use, it is not necessary to calibrate the machine. With standard vinyl
the accuracy is within 0.2%. However if high accuracy between different vinyl or colors is
needed, then calibration is necessary.

Calibrating the media (Length calibration):

1. Power on the cutter, load media, and mount knife (see section 1).

NOTE: The wider and longer the loaded media, the more accurate the calibration will be.

Use a piece of vinyl of maximum width and a length that is approximately 1.5 times the
width.

2. Press .

The main menu will appear on the screen.

3. Press

.

The different tests and calibration routines will appear on screen.

4. Press .

The cutter will reload the media and perform the length calibration test. Take out the media
and measure the length of the cut line with a ruler (measuring device). The length that has to
be entered is the distance between line 1 and line 2 as shown in the figure.

1 2

FIG 2-7

2-7 LENGTH CALIBRATION PATTERN

NOTE: The cutter will only be as accurate as the accuracy of the calibration. If the ruler
(measuring device) is inaccurate, then re-calibrating may make the cutter’s accuracy worse.
The accuracy of calibration will be directly reflected in the cuts. Set the cutter to Metric to
do the calibration. It is more accurate than the English unit system (see Panel Units:).

5. Press to proceed with the calibration, press to stop.

6. Use or to change to the value of the measured length between the

two cut lines down the length of the vinyl roll.

7. Press to confirm the value of the measured length.

TIP: Once this user is calibrated, change the user name. This makes it easy for future
reference.

2.6 How to track difficult media

Some cutting media is not designed for use on a drum driven plotter. In most cases the
cause is a none rigid backing. A possible solution for this problem is using paneling. The
option paneling divides the whole job into panels in the media direction.
It then cuts out panel after panel making sure it does not have to transport the media back
and forth over long distances.

NOTE: Paneling has been developed in order to achieve better closing of figures on
material which is difficult to track accurately. It does NOT mean however that with paneling
these materials can be cut within the regular Summa specifications of tracking and
accuracy. Recommended panel sizes are between 5 – 10 cm

3 OPOS (Optical POSitioning)

3.1 Introduction

Contour cutting is made possible by the highly accurate Optical Positioning System (OPOS)
with camera.

The OPOS camera, which is mounted in the tool carriage, registers printed markers that are
placed around the graphic. Because of this registration process, OPOS-CAM can determine
the exact position of the printed graphic.

Many versions of cutting software have the built-in capability to make contour cutting user­friendly and automatic.
Some software are fully automatic and take care of placing of the markers, sending data to
the cutter and processing the camera data.
Most software place the markers, send data to the cutter and use the utility Summa Camera
Control.
Please refer to the user’s manual that came with your software or contact your software
dealer for details.

3.2 Summa Camera Control

The program is used to process the
data from the camera. The program
should run in the background.
When the program is started, the
driver for the camera is also started.
This means that it is necessary to
power on the cutter before starting
the camera control program.
When the program is stopped, the
driver for the camera is stopped also
(this is the same as performing a save
removal).
Minimize the program after starting it
up. It will be minimized to the tray
and pop up when the markers are
read on the cutter.
The full explanation of the
possibilities of camera control are
explained in section 3.6

3.3 Calibration of OPOS-CAM

To ensure that OPOS-CAM is working accurately, a calibration is necessary. The OPOS
calibration is the calibration of the distance between the knife tip and the sensor. After a
calibration, a reference test has to be done to check.

1. Switch the cutter on and load black vinyl with white backing. Make sure cutter is

connected to the computer and the program camera control is running

NOTE: Black vinyl with white backing MUST be used when calibrating OPOS-CAM.

2. Set the head’s origin above a clean, blank part of the vinyl.

3. Press .

The main menu will appear on screen.

4. Press .

The configuration menus will appear on screen.

5. Press .

The different OPOS-CAM configuration menus will appear on screen.

6. Press .

“Weed out Rectangle” will appear on the display.

7. Carefully weed the rectangle, making sure the small squares stay on their place. Press

.

OPOS will read the edges of the square and calibrate itself accordingly.

NOTE: In order to keep the accuracy of the OPOS camera as high as possible, do this
calibration each time the knife is been replaced.

8. Start Summa Cutter Control.

NOTE: Reading cutter info may not work properly when camera control is running,

however sending data works. Leave summa camera control running

9. Click on .

3.4 Basic OPOS-CAM operation

In general, contour cutting includes the following steps:

 Create a graphic.
 Print the graphic (laminate if necessary).
 Load the graphic into the cutter.
 Set the necessary parameters for OPOS-CAM.
 Load the media and register the markers.
 Cut the graphic.

NOTE: After loading the media, change the origin so that the knife tip is above the first
marker. This will make it possible to do the rest of the procedure from behind the computer.

NOTE: Make sure the program Summa Camera Control is running on the computer.

Most cutting software do all this automatically. Once the OPOS- and cut data is sent to the
cutter, the knife is set above the first marker and the program Camera Control pops up.
Click on the ‘Digitize Marker’ tab, and then click on the picture area.

If the marker is recognized, then a
green box is shown around it. Click
‘Apply’ if so. The cutter will read the 4
markers and cut out 1 OPOS design.
If the marker is not visible, then the
paper can be moved around in the
cutter by clicking in the picture area
(the point clicked is repositioned to
the middle).

If this does not work, then the set the
tool carriage correct by going to the

cutter, pressing on

touch
screen and then using the arrows to
position the knife above the marker.

Pressing switches back to
what the camera sees. A white dot in

3.5 Automating Tasks with OPOS-CAM

OPOS-CAM allows the user to automate certain tasks, thus reducing user intervention and
production time. When cutting multiple graphics, the user only needs to move the OPOS
camera above the origin marker of the first graphic; cutting subsequent graphics do not
require additional user input.

There are two multiple-job situations in which contourcutting can be automated:

 When cutting multiple (copies of a) graphic(s) on the same media roll.
 When cutting the same graphic on multiple media sheets.

Most automated tasks are organized from within the cutting software. However, when the
same graphic contour needs to be cut out, then the automatic tasks also involve some
manual manipulation.

Before using the automating features, note the amount of your cutter’s RAM. If the cutter’s
RAM is greater than the job’s file size, then the automating features may be used. If the
cutter’s RAM is less than the job’s file size, then the automating features may not be used.

3.5.1 Cutting multiple copies of a graphic on the same roll

If the same graphic design has been printed on a roll with equal distance between the
different graphics, then this feature can be used.

First, load the media and be sure the parameters of the markers are set correctly.

Cutting multiple copies of the same graphic on the same media roll:

1. Press .

of sensing and cutting will repeat automatically until all remaining contours have been cut.

3.5.2 Cutting the same graphic on multiple media sheets

If the same graphic design has been printed on a multiple sheets, then this feature can be
used.

NOTE: The sheets should be more or less the same size, and the graphics on them
should be oriented and positioned the same way.

First, load the media and check that the parameters of the markers are set correctly.

NOTE: Do not change the origin after loading the sheet.

Cutting the same graphic on multiple media sheets:

1. Maximize Camera Control .

6. Raise the pinch rollers and manually remove the sheet.

7. Insert the next sheet into the cutter. Lower the pinch rollers.

NOTE: The second and any following sheets must be loaded in the cutter at the same

position as and with the same orientation of the first sheet. When in OPOS sheet mode,
the cutter stores the distance between edges of the sheet and the first OPOS marker.

NOTE: For WinPlot set the option in the output window to ‘feed after job’.

TIP: Use easy orientation points to be able to quickly position the sheet. In the figure

3.6 Detailed Summa Camera Control Operation

The camera option cannot work without it being connected to the computer. If the cutting
software is not equipped with such a possibility, then the utility Summa Camera Control can
do this.
It is best to minimize camera control (to tray) after it has been started
It will then pop-up when necessary.
If the cutter is switched off for a long time, then it is advised to close the program, otherwise
the program will continuously try to start the video driver.
To do this, right click the camera control icon in the tray.

3.6.1 Main Window tabs

The program has 5 tabs, the first tab gives information about the connection with the
camera.

The second tab is used to set the camera above the marker and check whether the system
has recognized it.

A green square will be visible around a marker if it is recognized as a marker.
The media in the cutter can be moved by clicking with the left button of the mouse in the
video area. If that is done, then the image (and media in the cutter) will be repositioned so
that the point that was clicked will come in the middle of the video area.
Otherwise said, clicking in the top half of the video area will move the media forward,
clicking in the left have of the video area will move the tool carriage to the left.
It is not necessary to get the marker in the middle of the video area, once it has been
recognized (green square around it) click ‘Apply’ and the rest of the markers will be
registered and the contours will be cut.

The third tab is used when the marker is not immediately recognized.
If no green rectangle was automatically drawn around the marker, then click on the third
tab (Marker Shape) and click on the button ‘Marker Shape’. A green square, slightly larger
than the marker will appear in the video area. Drag it with the mouse above the marker. This
will force the recognition of the marker. A window will be pop up given the user the chance
to store the marker shape (under a chosen name) so it can be used for recognizing the rest
of the markers of the job.
If the customer marker is not necessary any more, then the marker recognition can be set to
default again.

The fourth tab is to store patterns which can interfere in the marker detection.
For this the camera has to set on a area on the media where there is nothing printed. Then
the pattern can be saved when ‘Media filter is clicked’ When the media filter is then chosen,
then the pattern is subtracted from the reading in order to get a clearer marker. This mode
can only be used in very special cases and probably will reduce the accuracy. It is usually
used to filter out shadows.

3.7 Detailed OPOS Operation

3.7.1 Creating the graphic with the markers

1. Create the graphic and contour cut line(s). For easier handling, place the contour line(s)

on a different layer.

NOTE: Do not place contour lines along the edges of graphics or the slightest
movement in the media may result in an unsatisfactory cut. Instead, practice one of the
following techniques:

 Place contour lines just inside the graphics (recommended) (1).
 Place contour lines outside the graphics (2).
 Create thick borders around graphics and place contour lines inside these borders (3).

(1) contour line

inside graphic

recommended

(2) contour line

outside graphic

(3) contour line

inside a thick border

Contour line on

edge of graphic

2. If necessary, make additional copies of both the graphic and its associated contour.

3. Insert a marker to represent the Origin. The marker must be a black square. Each of the

marker’s four sides should measure 2mm but must not be less than 2mm or more than
5mm. (1=X-size 2=Y-size.)

S CLASS™ with OPOS-CAM User’s Manual

Contour Cutting 3-16

4. Set the line style of the marker to None. Line styles of varying thickness can alter the

size of the markers. Make sure there is a white margin of about 3 to 4 times the marker
size around the marker (in the above picture this area is represented by a gray area). If
anything is printed within this margin, the sensor may be unable to locate the marker.

5. Make sure that the Origin marker is situated below and to the left of all contours to be

cut.

6. Insert horizontally aligned copies of the Origin marker at regular intervals (X-Distance).

Together, these markers indicate the X-Axis.

The X-Distance (1) is the distance from the lower left corner of one marker to the lower left
corner of the next marker and depends on several factors. The X-Distance must be known

when setting the OPOS parameters manually.

1

NOTE: OPOS will operate faster as the X-Distance increases. Conversely, OPOS will
operate more accurately as the X-Distance decreases; however, the impact on accuracy
is minimal. Recommended distance between the markers is 400mm. Maximum X­Distance is 1300mm.

7. Make sure there is enough white space around each marker. The X-Distance should be

decreased if the margin of white space around the marker is not 3 to 4 times larger than
the marker itself.

8. Make sure that the markers are perfectly level with one another.

9. Make a copy of the row of markers created in step 5. Place this new row above the

graphic to indicate the Y-Axis.

S CLASS™ with OPOS-CAM User’s Manual

Contour Cutting 3-17

The Y-Distance (2) is the distance from the bottom of one marker to the bottom of the next
marker along the Y-Axis. The Y-Distance must be known when setting the OPOS parameters

manually.

2

10. Make sure the two rows of markers have not shifted along the X or Y Axes.

11. Check to be sure that graphics, markers and contour are each in a separate layer. Copy

the origin marker for origin reference in the layer of the contours.

NOTE: The layer with the graphic and the layer with the markers must be printed out.
The layer with the contour lines and the origin reference must be cut out.

NOTE: The optimum marker size depends on the type of printer and the X and Y
distance of the markers.
Inkjet printers with a lot of bleed require slightly larger markers. Some tests will be
needed with the printer in question to decide on the right marker size.
If the X distance is relatively large (> 800mm), then slightly larger markers could be
used.

S CLASS™ with OPOS-CAM User’s Manual

Contour Cutting 3-18

3.7.2 OPOS XY

There exists a function in OPOS to compensate for curved printing errors in the Y axis also.
This is called OPOS XY. An extra line needs to be printed with the design to be able to use
the OPOS XY functionality.

2

1

2

3

The line may be added between or above the front Y markers. The distance between the
centre of the markers and the line should not be more then 20mm( distance 1). The left and
right margin between line and marker should be 10mm for optimal sensing (distance 2).
The line itself should be at least 1mm thick. It is not necessary to have a white area between
the extra line and the rest of the design.

When OPOS XY is enabled, then the OPOS sensor will measure points along the extra line.
The number of measuring points will be calculated by the cutter and will depend on the
width of the design.

NOTE: The default setting for OPOS is OPOSX. If the OPOS XY functionality is needed,
then the user must set change the setting ‘alignment mode’ in the Opos Setup to OPOS
XY by hand on the control panel (see section 4.3.1.4) or via the cutting software.

NOTE: Some cutting software do not support the OPOS XY feature. If they also send the
alignment command ‘OPOS’ to the cutter, then they block the OPOS XY feature of the
cutter. If it is possible to define a line by hand in the design so that it meets up to the
specifications above, then the blocking of the software can be neutralized by using the
setting: ‘FORCE OPOS XY’ in the alignment mode.

3.7.3 Printing the graphic

1. Print the graphic and its markers with a printer (scale = 100%). When printing on a roll,

make sure that the graphic’s Origin marker coincides with the media’s origin (1).

1

2. Make sure there is at least a 1cm (0.4in) margin on each side of the graphic (2). A 2cm

(0.8in) margin is preferable. There must also be a front margin of 1 cm (3).

3.7.7 Cutting the contour

1. Make the layer containing the contour lines visible and printable. Do the opposite with

the print data.

2. Make sure that the origin marker is also defined as a contour. This will be used as the

origin for the cutting.

3. Once you are using the cutting software, it may be necessary to collectively rotate the

contours and markers so that the Origin marker (1) is situated in the bottom left corner
of the cutting area (2) as viewed on the screen. If your cutting software’s default
orientation is not set to “landscape,” the contours and markers will need to be rotated.

Orientation needed in most cutter software. Orientation when using WinPlot

4. Make sure that the cutter is connected to the computer and that the cutter is switched

on. The cutter’s touch screen should indicate that the cutter is ONLINE.

3.8 Cutting through

The cutting through functionality is focussed to cut simple shapes (e.g. rectangles). It is
most used in combination with contour cutting.
An interrupted cutting line makes sure that the material remains together thanks to the
small media ‘bridges’. When the job is finished the cut pieces can be torn out.

FIG 3-3

3-3 FLEXCUT PRINCIPLE

Some cutting software can recognize the difference between a contour line and a cut­through line. The software sends then first the data of the contour lines to the cutter, and
then it activates FlexCut, panelling mode and vector sorting and sends the data for cutting
through to the cutter.
If the cutting software cannot do this, then the user needs to first send the data of the
contour lines separate, set the cutter manually in FlexCut mode and then send the data for
cutting through.

15. Check if the result is the satisfactory. If not change one of the 4 parameters above.

Reducing the velocity can also improve the result. It is never recommended to use
cutting speeds larger then 400mm/s (16 ips) with cutting pressures above 170 gr.

Note: It is not always easy to find the correct balance between cutting deep enough
making sure the pieces can be taken out easily, and not cutting too deep making sure
the material keeps it strength while cutting. Sometimes this balance doesn’t exist
meaning that this material can’t be cut through with satisfactory result.

Note: FlexCut parameters are always metric, regardless the value of the panel Units
parameter (see section on Panel Units:)

Note: When cutting through, it is recommended that parallel lines are at least 1 cm
away from each other. Otherwise, while cutting the second line, the first line may come
loose and cause trouble.

Detailed Operation 4-3

4.3.1 Settings

This menu bundles all the settings of the S CLASS™ cutters. All settings in this section, apart
from the OPOS parameters, are user-dependent (information is contained within each of
the eight individual user settings, see section 4.3.3.).

4.3.1.1 Tool

The Tool submenu is used to select the default tool at power-up.

Press the button, then use or to change the tool to another default tool.

Press to confirm or to cancel. After changing the tool, the cutter will ask
the user to confirm that there was a tool change just before it comes online.

NOTE: Do not forget to check and/or recalibrate the tool settings when a tool has been
changed (see section 2.2.1). Also, OPOS calibration must be redone (see section 3.2.1).

4.3.1.2 Advanced cutting

The cutting menu groups the different parameters to optimize the cutting quality.

Overcut:

The Overcut submenu enables you to generate an overcut in order to facilitate weeding the
cut. Each time the knife goes up or down, the cutter cuts a bit further. Figure 4.3 below
shows what overcut does.
The overcut setting can be disabled (=0) or set to any value between 0(=off) and 10. One
unit is about 0.1 mm or 0.004 ".

OptiCut is default-set to OFF.

Press the button, then use or to set OptiCut to ON or OFF. Press

to confirm or to cancel.

S CLASS™ with OPOS-CAM User’s Manual

Detailed Operation 4-4

FlexCut:

FlexCut can be set to OFF, Fast, or Accurate. When the cutter is set to Fast or Accurate, it will
alternately cut a certain length with full pressure, and a certain length with reduced
pressure. The advantage of the FlexCut feature is that it cuts completely through the
material, yet allows the material to stay together by means of the small media bridges.

Fast is the quickest mode, but it is less precise due to the pressure changes during the
cutting.
Accurate is much slower, but much more precise, as the cutter stops at every change of
pressure.

There are 4 typical FlexCut parameters:

1. Full pressure: This parameter determines full pressure used during FlexCut mode.

2. Full pressure cut length: This parameter determines the length that is cut with full

pressure, usually the length that will be cut all the way through.

3. Flex pressure cut length: This parameter determines the length that will be cut with

reduced pressure or without pressure. This is usually a much smaller value than the
full pressure cut length – this is the length of the media bridges.

4. FlexCut pressure: This parameter determines the pressure of the Flex pressure cut

length. This is usually a reduced pressure so that the knife only scratches the media or
cuts it only halfway through.

Procedure to set the correct parameters for FlexCut:

1. Press

then use

or

to choose the FlexCut mode.

2. Press to confirm or to cancel.

3. Press , ,

Panels:

There are 4 specific parameters in the ‘Panels’ submenu:

1. Panels: This parameter switches panels on or off.

2. Panel size: This parameter determines the length of the panel.

3. Panel replot: This parameter determines if the design has to be cut more than once on

top of itself, this per panel. Panel replot is used for thick media and media which is
difficult to cut. The value of this parameter is disregarded if paneling is set to off. If
this parameter is set at 0, then the cutter will cut each panel only once. If it is set at 1,
it will cut each panel twice,…

4. Sort vectors: See paragraph below

Paneling is used for several different applications. Below are the typical settings for the
most 3 common applications.

Cutting through: This is explained in section 3.5. Typical settings for the parameters are then:
Panels: ON; Panel size 5 – 10cm; Panel replot: OFF; vector sorting: DIRECTIONAL.

Tracking difficult media: This is explained in section 2.7. Typical settings for the parameters
are then: Panels: ON; Panel size 3 – 10cm; Panel replot: ON/OFF depending on the thickness
of the media; vector sorting: DRIECTIONAL/OFF depending on needed knife pressure and
backing of the material.

Roll Up: The roll-up system is an option that can be added on the larger S CLASS models
refer to the manual for the roll-up system for more info. Typical settings for the parameters
are then: Panels: ON; Panel size 50 – 100cm; Panel replot: OFF; vector sorting: OFF. Another
recommended setting when using the roll-up system is to set panels to off and use the
automatic paneling of 100cm and set roll-up to ‘AFTER AUTO-panel’. See section on ‘Roll up
media:’

Sort Vectors:

Sorting vectors is a sub menu of the panel menu, but because of its importance explained
separately.
There are three options in this menu.

1. Off: When vector sorting is set of, then the cutter does no optimizing of the vectors.

This is used when the intelligence of the cutter driver is preferred.

2. Directional: If set to directional, then the vectors are optimized for cutting direction

(media movement). This used when the cutting pressure has to be set relatively high (
for example with cutting through).

3. Starting point: This option optimizes the starting point for closed curves. This is used

when the users sees that the curves do not close as they should.

4.3.1.3 General

Media sensor:

The media sensors detect whether media is loaded and also detect the end of the media.
The sensors prevent damage to the cutting strip and knife tip. The sensors can be activated
or deactivated with this menu.
When the sensors are activated, the cutter searches for the front end of the media during
the loading procedure. If it does not find it after returning the media for 1m (+/- 3 feet), it
stops returning the media and sets the origin in the x-axis there.
The cutter will also stop, during the loading procedure or while it is cutting, if the rear
sensor detects the end of the media.
The cutter does not search for the front end of the media and assumes that the loaded
media is endless if the sensors are not activated.

Press the button, then use or to activate (ON) or deactivate (OFF) both or
just front sensor (FRONT OFF) only.

4.3.1.4 OPOS

The OPOS settings are explained in detail in section 3, except for the Alignment mode.
There are three additional alignment methods available on all cutters:

X-Alignment, XY-Alignment and XY-Adjustment. These alignment methods can be used if
the combination of marker color – media color cannot be read by the OPOS camera.
These alignment methods require that the user manually register markers using the cutter’s
keypad. Most cutting software can automatically put these markers around the printed
graphic.

X-Alignment compensates for errors in media alignment, by rotating the graphic’s contour.
This alignment method requires that the user specify the Origin and one point along the X­Axis. X-Alignment is the simplest alignment method.

XY-Alignment compensates for errors in graphic rotation and skew. Skew errors occur when
the graphic’s X and Y Axes are not perpendicular. This alignment method requires that the
Origin and one point along both the X and Y Axes be specified.

XY-Adjustment compensates for errors in graphic rotation, skew, and scale. Scale errors
occur when the graphic’s printed size is different from the graphic’s original size as created
in the imaging software. X-Distance and Y-Distance parameters are required. These
parameters define the distance between the Origin and X-Axis point, and between the
Origin and Y-Axis point. XY-Adjustment is the most accurate manual alignment method.

Press the button, then use or to change the alignment method.

Press

to confirm or to cancel.

Default alignment method is OPOS.

OPOS paneling:

With this option, the markers can be read in panels. The OPOS sensor will read markers
according to panel size, instead of loading them all be.

OPOS Panels can be set to OFF or ON. When set to ON, then the sensor will load only 2

markers in X-direction when loading OPOS. Other markers will be read when unrolling
media. Must be used with internal or software paneling.

4.3.1.5 Communication

The communication settings menu groups all the parameters that determine the speed and
method of communicating with the computer, as well as the language protocol.

NOTE: The serial parameter settings for RS232 must match the computer RS232 port
settings. Use Summa Cutter Control to check RS232 port settings.
Some software uses the Windows default serial port settings. Summa Cutter Control uses its
own and can be easily accessed. Baud rate setting is selected automatically.

Baudrate (RS232):

The Baudrate is the speed at which the data is sent from computer to cutter.
Possible settings are: 2400 bps, 4800 bps, 9600 bps, 19200, 38400 and 57600 bps.

NOTE: If the cutter’s Baud rate setting does not match the Baudrate settings of the
computer, then computer and cutter will not communicate.

Press the button, then use or to change the Baudrate.

Press to confirm or to cancel.
The Baudrate is default set at 9600 (this is the Windows default setting for a serial port).

Parity (RS232):

The PARITY submenu is used to set or modify the byte format and parity type for serial
communications between the cutter and the host computer.
There is the choice between None, Mark, Even, and Odd.

NOTE: If the cutter’s parity setting does not match the setting of the computer, then
communication between cutter and computer will be erratic or will not work at all,
depending on the commands the cutter receives.

Press the button, then use or to change the value.

Press to confirm or to cancel.
The parity is default set at None.

RTS/DTR (RS232):

This parameter controls the “handshake” between cutter and computer.
Possible settings are Toggle or Always High.

NOTE: If the RTS/DTR setting of the cutter does not match the setting of the computer, then
communication between cutter and computer will not work when large packets of data are
sent from computer to the cutter. A typical fault in this setting is a job that begins without
any problem and then suddenly stray lines are cut out (or drawn).

Press the button, then use or to change the value.

Press to confirm or to cancel.
RTS/DTR is default set to Toggle.

Emulation language:

The S CLASS™ cutters support DM-PL , HP-GL , HP-GL/2 and Auto.
DM-PL is the recommended plotting language and usually gives the best cutting quality.
HP-GL emulates an HP 7585B, 7580B, 758X Series HPGL printer.
HP-GL emulates an HP Draftmaster RX / SX / MX 7595B type printer.

Press the button, then use or to change the plotting language.

Press to confirm or to cancel.
The default setting is Auto.

HP-GL origin:

This option is not visible when the plotting language is set to DM-PL.
The origin can be set to Right Front or Center.
If the cut is found to be incomplete, and is located all the way in the upper left corner of the
media, then modify the HP-GL origin setting to Right Front.
If the cut is found to be incomplete, and is shifted to the lower right corner of the media,
then change the HP-GL origin setting to Center.

Press the button, then use or to change the plotting origin.

Press to confirm or to cancel.
The default origin setting is Right Front.

DM-PL addressing:

This option is only visible when the plotting language is set to DM-PL.
The user-addressable curve resolution can be set to 0.025 mm or 0.001" or 0.1 mm or 0.005".

Press the button, then use or to set the resolution.

Press to confirm or to cancel.
The default addressing resolution is 0.025 mm (Europe) or 0.001" (US).

USB class:

USB class can be set to Summa USB port 1, Printer Uni (unidirectional), Printer Bidi
(bidirectional), Summa USB port 2, Summa USB port 3, or Summa USB port 4.
Printer Uni and Printer Bidi are for use with printer adaptors with either network or wireless
connection.
Because of the different USB id’s, the computer can make a distinction between several
cutters attached to it (maximum 4).

Press the button, then use or to change the USB Class.

Press to confirm or to cancel.
The default USB class mode is Summa USB port 1.

NOTE: The minimum USB driver version required for attaching more than 1 cutter to the
same computer is 6.2. The change in USB class becomes active only after rebooting the
cutter.

NOTE: The USB id in the cutting software has to be the same as the chosen USB id in the
cutter. Each time a new USB is select on the cutter and connected for the first time to the
computer, the wizard for installing a driver will be started by Windows.

NOTE: The USB id has to be set to USB in order for the camera to work.

4.3.1.6 Speed in detail

This menu groups all the parameters that affect the throughput of the cutter. The velocity
and acceleration settings are explained in section 2.3.

Velocity long vectors:

Some vinyls have the tendency buckle when large designs are cut out. To avoid this, the
speed needs to be reduced. This option does this automatic so that the speed and
accelerations of small vectors are not affected when the speed is brought down.

Press the button, then use or to set the speed to automatic or normal.

Press to confirm or to cancel.
Velocity for long vectors is default set to automatic.

TurboCut:

TurboCut increases throughput without raising the overall speed of the plotter by speeding
up the drag movement. The cutting time reduction is significant, especially when cutting
small, detailed designs. However, some thicker materials might not cut well with this
feature turned ON.

Press the button, then use or to activate or deactivate TurboCut.

Press to confirm or to cancel. TurboCut is default activated.

FlexCut velocity:

FlexCut uses higher knife pressures. Higher knife pressures need lower cutting speed.
With this parameter the velocity of FlexCut can be set independent from the normal cutting
velocity.

NOTE: It is recommended to use speeds lower then 400mm/s for FlexCut.

4.3.2 Tests and setup

4.3.2.1 OPOS settings

The OPOS settings are explained in detail in section 3. The OPOS settings are also found in
the Settings menu.

4.3.2.2 Length calibration

Length calibration allows the length of the lines cut to be adjusted to within the
specifications.
For instance, if a cut line should measure 100 mm exactly, the cutter can be adjusted for any
discrepancy.
Calibration is explained in section 2.5.

4.3.2.3 Coil setup

This test is used to calibrate knife and pen pressure and to set the knife and pen “landing.”
The cut quality is seriously affected by incorrect landing settings. Before changing these
values, write them down, as there is no default setting for these parameters.
After adjustment, the value is saved in the system’s non-volatile RAM.

Press the button, then use or to switch between the parameters and use

or to change the value of the highlighted parameter.

Press to confirm or to cancel.

Setting 40g pressure and 600g (400g) pressure.

To execute this test, a tension gauge of ± 100 gr and ± 600 gr is required.
Measure the pressure on the knife with the tension gauge (read value from the gauge when

knife just lifts from the media.) Use

or to change the value of the
parameter so that the readout on the tension gauge matches the value on the touch screen
(40g, 400g or 600g depending on the parameter that is calibrated).

Setting the landing

The landing determines, among other things, the force at which the tool hits the media.
When calibrating the landing, the tool holder with the knife must be inserted in the head.
Be sure that the knife does not protrude.

Use to lower the landing value until the tool is in the “up” position. Then use

to raise the value of the parameter. With each unit of change, continue checking if
the tool is completely down yet. Once the tool is completely down, raise the value back up
three units, and this becomes the proper setting.

4.3.2.4 Calibrate knife

This test will only show when the machine type is set to a tangential machine and if the
current tool is set to a tangential knife. This test is explained in section 2.2.4.

4.3.2.5 Factory defaults

This option defaults all user parameters to factory default.

4.3.2.6 Confidence test

The confidence test performs a quick electrical and mechanical test of the cutter to make
sure that the cutter is fully operational. A media sheet of at least A3/B-size should be used
for this plot. This test is always cut at the left side of the loaded media.

4.3.2.7 Media sensor setup

The media sensor setup option is a useful routine for checking whether the front and rear
media sensors are functioning properly and whether the switching levels of these sensors
are correctly set.

1. Press or to select the sensor that will be tested.

2. Put a piece of media half on the chosen sensor and under the two outer pinch rollers.

Press .

3. There are five levels of sensitivity to choose from.

4. Use or to change sensitivity level.

After choosing a sensitivity level, there will be a rectangle next to the sensitivity. When the sensor
is covered then the rectangle will be (completely) filled with black squares. When the senor is
uncovered, there will be (almost) no black squares in the rectangle.

The black stripe in the rectangle is the trigger level at which the cutter decides whether there is
media in the machine or not.

5. Use and to change the trigger level if necessary.

Ideally there would be 2 to 4 black squares when the sensor is uncovered, the rectangle is
completely filled when it is covered, and the trigger level is set in the middle

4.3.2.8 DIN A4 Test

The DIN A4 Test also performs an electrical and mechanical test of the cutter, in order to
check the cut quality, but also provides the user with feedback on knife setting, knife
pressure, knife offset, and cutting depth.

This cut is always run as a DIN A4 portrait/A-size image, regardless of the actual size of the
media loaded. If the media loaded is smaller than DIN A4/A-size, part of the outer box will
be clipped (not cut).

4.3.2.9 RS232 test

The RS232 test routine verifies the cutter’s RS-232-C serial communications (transmit data,
receive data, and hardware handshaking) circuits. This test does not require pen, knife, or
media to be loaded.

To run the RS-232-C test, proceed as follows:

1. Unplug the RS-232-C data cable from the rear panel of the cutter.

2. Use a loop back test cable to connect pin 2 of the cutter’s data connector to pin 3 and

pin 7 to pin 8.

3. Press button. The cutter will start transmitting and receiving data at all available baud

rates and parity settings. The length of the transmissions will vary because of the
different baud rates used. The unit then checks the hardware handshake lines.
Afterwards it will report on the touch screen whether it passed the test or not.

4. Upon completion of the test, remove the loop back test cable from the cutter’s rear

panel RS-232-C connector.

5. Plug the RS-232-C data cable into the connector.

4.3.2.10 Calibrate touch screen

This option makes it possible to calibrate the touch screen. Perform this calibration if the
illustration of the button on the touch screen does not match the area that needs to be
pressed to activate the button.
Press button to start the calibration and follow guidelines on screen.

4.3.2.11 ROM revision

Press the button to view information about the cutter’s ROM revision. This information is
often helpful to technicians when diagnosing problems over the telephone.

4.3.2.12 Copy current user

Press the button to copy the user parameters from the current user to all the other users. It
is recommended to do this only when the current user is user 1.
