Personal Computer Specifications

This specification describes the hardware and application software requirements for
the Personal Computer that is connected to the PAXAR 676 Printer.

The PAXAR 676 Printer uses a DOS Version of PCMate or a Windows version of
“PcMate Plus / Formatter ”. These applications create the tag or label formats
(layouts) then fill and transfer data to the printer through the serial port of the
computer.

“PcMate Plus / Formatter ” Requires the following;

- IBM® PC or compatible

- Microsoft Windows® 95 or higher (Including Win 2000, ME, and NT)

- 16 Megabytes RAM (minimum) - 32 Megabytes recommended

- 50 Megabytes (minimum) free disk space

- Pentium or Pentium Type processor - 200 Mhz or higher

- 3-1/2" floppy drive

Refer to your specific software package for proper installation procedures.

10 • Description / Specifications

Customer Responsibility

Location of Printer

The printer weighs approximately 70 Lbs (32 Kg) and requires a table of sufficient
quality and strength to handle this load while the printer is operating. PAXAR
recommends an industrial type work table having the approximate dimensions of 96"
wide to 30" deep to 32" high. Refer to Figure 2.

Figure 2 - Recommended Workstation Layout.

The location of the PAXAR 676 printer should be based on human factors. The
printer should be located in an area that maintains optimum flow of your product
while providing for the operator’s comfort. PAXAR has taken significant steps to
ensure that the operator controls and operations are easily accessible. This goal can
only be met, however, if the printer is also located with human factors in mind.
These include the height of the printer, the space around the printer, and the
accessibility to the printer.

The PAXAR 676 printer is a high-resolution thermal printer. While PAXAR has
designed the printer to be reasonably quiet, it is recommended to locate the printer in
an area where printing and cutting repetitious noise is acceptable.

The unit should always be operated with the cover closed to minimize the amount of
dust and dirt in the machine.

Users Manual Model 676 Customer Responsibility • 11

AC Power Line

PAXAR requires that the electric service be 10 Amps @ 115VAC or 10 Amps @
230VAC. This will allow the computer and any additional support or service
equipment to be plugged into the same service.

Any electrical service which is supplying a PAXAR printer or peripheral equipment
connected to a PAXAR printer should follow standard electrical code practices
including proper grounding and neutral requirements.

The PAXAR printer was designed to operate in an industrial setting for extended
periods of time; however, the printer is controlled by a microprocessor which is very
sensitive to brownouts or power spikes. For this reason as well as the minimum
recommended current supply, PAXAR recommends that a separate “clean” service
be installed or reserved for the exclusive use of the PAXAR printer and it’s
peripherals.

Printer Unpacking / Installation

Unpacking

The PAXAR printer is shipped in a large plywood crate which may be difficult to
move by hand.

DO NOT REMOVE THE PRINTER FROM THE CRATE OR UNPACK IN
THE SHIPPING / RECEIVING DEPARTMENT.

NOTE: Unpacking in the shipping/receiving department is not recommended for

the following reasons. First: The plywood crate in which your PAXAR printer was
shipped allows the printer to be moved with a forklift, forkcart or hand cart.
Because of the weight of the printer, it is easier and safer to use one of these devices
to move the printer to its intended installation location. Second: Leaving the printer
in the crate while it is being moved within your facility will help to protect the
printer during the movements to this new location. Once the printer has reached its
intended location you should begin the unpacking process.

Open the crate from the bottom by removing the six screws along the bottom of the
cover near the floor (See Figure 3).

Remove the plastic over the printer.

Remove all the smaller loss items from in and around the printer.

Unbolt the shipping bracket from the crate bottom.

Lift the printer onto the table.

Remove the shipping brackets from the machine.

12 • Printer Unpacking / Installation

Inspect the machine for shipping damage. If obvious damage is discovered, contact
PAXAR for further instructions - in the U.S.A. at (570)-888-9116. In countries
other than the U.S.A. please contact your local PAXAR supplier.

Save the shipping materials to relocate the unit or return to factory for service.

Inventory of Components

The following list shows the additional parts (pieces) which should be included in
your PAXAR 676 shipping crate. If anything is missing, notify PAXAR

Fuse Configuration

The main fuse(s) on the Paxar 676 are located inside the AC power entry receptacle.
The entry has a fuse drawer that holds the fuse(s) and selects the appropriate line
voltage. If the number in the window DOES NOT match the AC line intended to be
supplied to the printer, DO NOT plug the power cord in. Re configure as follows:

1) Using a flat blade screwdriver, open the AC entry by lifting the tab just above the
voltage indicator window.

WARNING: Attempting to open the AC entry with the AC power cord inserted into

2) Remove the red fuse drawer.

3) Remove all fuses and the fuse jumper if it is present.

4) Insert into the fuse drawer the correct number and style of fuses and fuse jumper
for your application.

Configuration Number One: Line voltage between the range of

it will cause damage to the AC entry.

90 - 132VAC @ 50 - 60Hz 1 Ph

1) Install one 921167 - 10.0A 250V Fast Acting 1/4 x 1 1/4"

2) Install one Fuse Jumper

See Figure FUSE1

Configuration Number Two: Line voltage between the range of

180 - 265VAC @ 50 - 60Hz 1 Ph

1) Install two 921168 10.0A 250V Fast Acting 5 x 20MM

NOTE: The fuse jumper must be removed to install both 5 x
20mm fuses.

The fuses must be between points A and B as shown not B and C.

See Figure FUSE2

4) Reinsert the fuse drawer into the AC entry with the desired voltage up.

5) Close the AC entry and verify the correct voltage is now visible.

14 • Printer Unpacking / Installation

Installing the Power Cord

A power cord is shipped with each printer. The cord for 115-volt printers, will use
the standard three prong plug used in the U.S.A. A 230-volt printer and some other
115-volt configurations must have the receptacle end of the connector removed and
the proper plug installed. It is the customers’ responsibility to have the plug and
alteration work done by a certified electrician. Paxar supplies printers to many
countries with many variations. Therefore we leave this to the customer to make the
proper selection for their country.

Installing the PC Interface Cable

The 676 requires a 9-pin RS232 cable. This cable is provided with the printer. If
the cable was not found it can be order from PAXAR (Part no. 351124).

The male end of the cable should be connected to the 9-pin D-shell female connector
that is located on the right side of the printer. The female end of the cable is made to
fit a 9-pin male RS232 connector on the back of the PC.

Installing the PC Software

The software to drive the Paxar family of printers is covered in separate
documentation. The "Formatter" software to create formats for the Paxar 676 printer
is a Windows application. The original software "Selfform" will not create formats
for the 676. The new "Formatter" package is capable of making formats for all
Paxar control printers.

The DOS version of "PCMate" has been updated to drive the 676 printer. PCMate
DOS version 3.10 or higher is needed for its use.

The printer is also capable of operating directly from a mainframe when using the
RS232 interface and Paxar's PCL command language.

Printer Operation

Loading Stock

LOADING STOCK FOR THE FIRST TIME

Figure 4 - Stock Threading

1) Adjust the unwind width wider than the roll of stock to be loaded. Set the stock

roll on the unwind between the guides with the stock unwinding from the top
clockwise. Adjust the unwind width down to the stock size without clamping
the core.

2) Adjust the web guides on the decurler bar to a width wider than the stock.

3) Remove the tape or pull the glued end of the stock loose from the supply roll of

stock. Pull off about 2 feet (.5 m) of stock to thread it through the printer.

NOTE: If the material was glued to the core, cut off all material that has glue on

any surface.

4) Open the hinged cover to the machine.

5) Open all the print heads by pulling the release knob and then rotating the print

head into the open latched position. The top two print stations have a pin in the
rear to hold them open. The bottom print station has a hole in the rear to hold
the print head slightly open to act as a bridge for the stock to pass over.

6) Open the feed rollers by rotating the feed pressure knob fully clockwise.

7) After looping the leading edge of the stock over the decurler slide it through the

funnel containing the registration sensor system. Keep the stock in the center,
as the printer is center justified.

8) As the stock exits the sensor area, continue to slide the stock through the print

stations.

9) Once the stock reaches the feed rollers it maybe necessary to hold the feed

pressure knob open in order to pass between the rollers. After exiting the feed
rollers enter the aux. feed and then through the knife into the stacker.

16 • Printer Operation

Butt Splice

10) Check that the stock is centered and tracking straight through the printer.

Adjust as needed.

11) Close the feed roller and only the print stations needed for the format.

12) Rewind any loose stock back onto the supply roll.

13) Adjust the web guides on the decurler down to the edges of the stock without

deforming the stock.

NOTE: DO NOT RUN BUTT SPLICES THROUGH THE PRINT STATIONS

The PAXAR 676 has been designed keeping the operators need to change supplies
quickly and often in mind. Re-threading the stock is quicker than butt splicing. If
however you have determined a butt splice is necessary, after loading a new roll of
stock onto the unwind tape the free ends together. Remove all slack by rotating the
supply roll counterclockwise. To prolong print head life it is highly recommended
that all hand splices be advanced beyond all three print stations before printing is
resumes. This can best be accomplished by using the stock presently in the print
stations to manually pull the new stock through and into the stacker. Once the butt
splice is in the stacker close the feed rollers and those print stations needed for the
format.

NOTE: Whenever stock of a different type or width is put on the printer, a sample

run should be performed. If the print quality / position is acceptable, you
can immediately begin your production run. If the print quality / position
needs to be optimized, refer to the Adjustments section and perform the
procedure needed to make the necessary improvement.

Web Guides

The Paxar 676 printer has been designed with the operators needs in mind.
Therefore there are only two sets of web guides in the printer that need to be
changed as the width of the rolls change for various width stocks. Neither of these
adjustments requires a tool.

The first guide is on the unwind itself. A knob located on the front of the unwind
adjusts the width of the guides on the unwind while maintaining center justification.
To increase the width - turn the knob counter clockwise. To decrease the width ­turn the knob clockwise. Adjust the unwind width wider than the roll of stock to be
loaded. Set the stock roll on the unwind between the guides with the stock
unwinding from the top clockwise. Adjust the unwind width down to the stock size
without clamping the core.

The second set of guides are located on the decurler just to the left of the stock
registration funnel. Once a stock is loaded and tracking straight through the machine
adjust this set of web guides down to the edges of the stock without deforming the
stock. If a large distance is to be covered loosen the plastic thumb screw and slid the
collar into the new position then retighten the thumbscrew. Fine adjustments of the
stocks web position can be made by simply moving the collar as a set in or out. If
the guides are too tight, the stock will have rolled up edges.

Print Head Operation

The print head modules are to be opened and closed for threading of stock and ink.
The unit must also be opened to clean the head and for print head replacement.
Later in the manual, under separate headings, cleaning and replacement will be
covered.

For clarity the print stations have been assigned numbers one through three from left
to right. The far-left print station prints the back; it is print station number one. The
center and right print stations print on the top; they are stations two and three. Each
print station has an interlock switch that prevents the printer from running with any
or all print stations in the open position if that print station is assigned in the format
being printed. If a print station is open, the display will read HEAD OPEN
STATION X.

WARNING: DO NOT TOUCH THE PRINT HEAD WITHOUT WEARING THE

To open the print heads for threading supplies or cleaning pulling the release knob
and then rotating the print head into the open latched position (see figure x). The top
two print stations have a pin in the rear to hold them open. The bottom print station
will remain open via gravity however it has a hole in the rear to hold the print head
in a slightly open position to act as a bridge when one is threading stock.

Figure 5 - Print Head Open / Closed

To close the head again pull the release knob and then rotating the print head into the
closed latched position (see figure 5).

Installing Ink Ribbon

The ink ribbon comes pre-packaged in a plastic bag. For best results, leave the ink
ribbon wrapped in this bag until you are ready to use it in the printer. Use the
procedure and diagram below for loading the ink.

Figure 6

1) Unwrap the ink ribbon and put it on the ink-ribbon supply arbor for the print

station to be loaded (Figure 6) by pressing it on to the arbor when the three slots
are lined up.

2) Make sure the ink ribbon comes off the roll in the direction shown and is

threaded as illustrated (Figure 6).

NOTE: A new ink ribbon has a leader that makes it easier to use when threading

the ribbon through the print area.

3) Place an empty ink-ribbon take-up core on the ink-ribbon take-up arbor for the

print station to be loaded. The ink take-up core must be at least as wide as the
ink supply.

4) Open the print head to the print station being loaded.

5) After starting the leader off the supply roll pull enough ink off to thread though

the print station and onto the take up core. The adhesive on the supply roll of ink
will be used to fasten the leader to the take up core.

NOTE: Make sure that the ink-ribbon take-up core and the ink-ribbon supply roll

are both against the ink backer plate so that the ink ribbon tracks straight
through the print station.

This screen is displayed while the Front Panel is initializing and waiting for the
Thermal Control Board (TCB) response. While this screen is displayed the code
will check the functionality of the LED's and the display. Each state of the LED's
will be checked - (red, green, amber and off). The LCD is checked by writing a
character to the display, checking for communications and then reading the character
back and comparing with the code. If an error occurs, the code will halt the
diagnostic test and blink the ERROR LED.

The keypad is also checked during DIAGNOSTIC TEST 1. Each key is tested to
see if it is stuck on. If a fault condition is detected, the test is halted and the screen
will display the first error key found with the following display:

Adjustments

Feed Roller Pressure

General

The rubber pressure roller is supported by an eccentric shaft mounted in bearings
located in vertical slots in the front and rear mounting plates of the drive module.
These bearings are supported by compression springs and controlled by cap screws
located in the top of the bearing mounts.

From time to time the feed pressure setting will need to be readjusted. This is
important to reduce any slip from too light an adjustment or any binds from too tight
an adjustment which will result in excessive roller wear or feed failure.

Adjustment Procedure:

1) Open the stock feed lever (fully clockwise) and remove the stock from the feed
module.

2) Loosen without removing the two cap screws located in the top of the bearing
mounts using the 9/64” ball driver from the tool kit.

3) Using a small piece of the same stock being ran as a "feeler" gauge tighten the
two 9/64” cap screws so that there is equal distance (just enough to cause the top
roller to rotate as the gauge is moved left and right) between the two rollers at
both outboard edges. This should be done with the stock feed lever closed (fully
counter clockwise).

4) Add 1/2 turn to each of the 9/64” cap screws from the previous adjustment.

5) Reload the production stock through the feed module.

6) Run the checkout format (found in the Printer Adjust Mode on the front panel)
and further adjust the two 9/64” cap screws an equal amount based on the results
as follows:

Using the scribe marks on the front of the machine cover measure the
length of the label. These scribe marks are 11 inches apart with the
tolerance of the label built into the right scribe. Align the left end of the
label to the left side of the left scribe and confirm that the right end falls
within the right scribe.

If the label produced measures less than 11inchs, tighten (clockwise) both
screws equally and repeat the measurement on a new strip.

If the 11 inch label produced exceeds 11inchs, loosen (counter-clockwise)
both screws equally and repeat the measurement on a new strip.

NOTE: Care should be taken to ensure that the label you use for the

measurement is an actual label produced after any adjustments
made. Run at least three labels between adjustments and use the
last label out to achieve this.

7) Once an 11-inch strip is achieved a final check for stock feed balance between
inboard and outboard can be made. Measure the distance between the main

36 • Adjustments

Sensors

vertical support plate of the printer to the inboard edge of the stock at both the
feed roller and the unwind. This measure should be the same distance at both
locations. To move the stock inboard at the feed roller, away from the operator,
loosen the outboard screw slightly. This can be done while running the printer.
To move the stock outboard at the feed roller, toward the operator, loosen the
inboard screw slightly.

Sensor Identification:

Stock Out

A micro switch located on the back of the unwind will detect when the stock core is
lifted when the stock is consumed and stop the printer.

Hole / Slot Index Registration

The hole / slot registration is via an optical sensor used in conjunction with an LED
light bar located in the stock funnel which allows the printer to register to pre­punched possible preprinted stock.

Reflective Index Registration

The same optical sensor used for hole / slot registration, allows the printer to register
to preprinted stock by detecting a black mark when the LED light bar is turned off
via the format.

Ink Out

Optical sensors located on each print station’s ink unwind arbor allow the printer to
monitor the availability of ink.

Roller Drop

An optical sensor on back of print station number two allows the printer to control
and register the platen roller position to perform ink save.

A micro switch on the back of the feed module will detect the position of the feed
module pressure knob and only allow the printer to operate with the feed pressure
knob closed.

Jam

An optical sensor located in the stacker will detect each cut label as it leaves the
cutter. If a cut fails to occur or a label remains in the sensor sight path, the machine
will stop.

Users Manual Model 676 Adjustments • 37

Full Stacker

A micro switch in the stacker rails allows the printer to detect a full load of labels in
the stacker. The stack full condition will stop the machine when the stacker is full.

Sensor Adjustments:

All the micro switches and optical sensors in your 676 printer were calibrated at the
time your printer was manufactured, however from time to time it may become
necessary to readjust / recalibrate due to the large variety of stocks and inks that can
be run on the machine.

Stock Out

With a full roll of stock loaded on the unwind with the unwind web guides properly
adjusted you should heard the switch click as you raise and lower the roll. If not the
switch bale is adjusted by carefully bending it as needed.

Print Registration Sensor Web Position Adjustment

If you are running sense mark media with a hole or slot for registration the
registration sensor web position must be adjusted for the sense mark media being
run:

1) Open the feed roller and print stations.

2) Move the stock by hand in the feed direction until the registration hold or slot

desired is in the slot on the sensor funnel over the red LED light bar.

3) Close the feed and those print stations needed for the format.

4) Slide the top sensor assembly using the sensor handle while looking at the sensor

LED on the front panel. When the LED turns on with the registration sensor over
the media in the vicinity of the hole / slot, and stays on, the sensor is over the
registration hole or slot.

If your machine stops, for no apparent reason, while it is in the middle of printing a
batch, you may be missing sense marks (three consecutive tickets in a row in which
a sense mark was not found). Check for the following:

- The front panel will display a screen indicating that there has been a missed
sensor error.

1) Check that the web guides have been positioned properly - both on the unwind
and decurler.

2) Check that the feed roller pressure has been set equally across the roller.

3) Check that the feed roller pressure has been set to pull 11 inches of media
properly.

4) Compare the actual feed length of the sense mark stock being run with the feed
length set in the format.

5) Repeat the sensor alignment procedure.

Print Registration Sensor Rotation Alignment

The optical sensor for the light from the LED bar for stock registration is mounted
on a square shaft directly above the web plate assembly, just prior to the first print
station. Although this bar is factory adjusted prior to shipment, it may become
necessary to readjust the bar to assure proper light reception if after following the
previous procedure the missed sense mark error continues to occur.

1) Remove the stock from the machine.

38 • Adjustments

2) Slide receiver block to its furthest rear travel (away from the operator).

3) Remove the back cover of the machine.

4) While holding the screw that secures the square bar to the machine upright, rotate
the square bar to align the sensor to the slot over the light bar. Retighten the
screw as needed.

5) Slowly slide the receiver block to its furthest forward position (towards the
operator) while confirming that the sensor alignment is maintained throughout its
travel.

Feed Open

If the switch is in need of adjustment - first check and adjust, as needed the feed
pressure, as it will affect the switch adjustment. With the machine rear cover
removed while opening and closing the feed pressure knob you should heard the
switch clicking. If not, the switch bale is adjusted by carefully bending it as needed.

Optical Sensor Electrical Calibration

Re calibration times are indicated in the troubleshooting section.

The following guidelines indicate the proper procedure used to calibrate these
sensors.

Note: Clean all optical sensors with clean compressed air or canned air prior to

adjustment as dust and debris will adversely effect their performance.

Print Head

There are three basic steps to calibrating each optical sensor.

1) Select the sensor to be calibrated in the Calibrate Sensors mode on the front panel.

2) Place media or ink as the case maybe in the appropriate sensor and press the enter
button on the front panel.

3) In the case of stock registration sensing reposition the media so that a hole / slot
or black reflective mark is in the sight path of the appropriate registration sensor
and press the enter button on the front panel. In the case of stacker jam sensor
reposition the media so the media is not in the sight path of the jam sensor and
press the enter button on the front panel.

Tangent

Proper print head tangent is perhaps the most important adjustment to make on a
thermal transfer printer. A printhead which is not properly adjusted will result in
poor print quality, poor heat dissipation which can reduce print head life, and
possible ink wrinkling problems. When the machine was manufactured, the print
head was adjusted to the proper tangent point on the platen roller, however, with
print head replacements the tangent point for the new print head may change. It is
therefore necessary to understand when and how to properly adjust the printhead
tangent. Before making any adjustment to any of the three print station tangent
points confirm the following:

Users Manual Model 676 Adjustments • 39

- Is the ink and stock loaded in the printer correctly?

- Is the proper ink and stock loaded in the printer for the format downloaded?

- Is the strobe setting(s) on the front panel set according to the ink and stock
loaded in the printer?

- Is the ink and stock of known types?

- Are the correct width platen rollers installed in the print stations for the stock
width loaded in the printer?

To actually adjust the tangent continue as follows:

1) Determine the print station that adjustment is needed.

2) Using the sight hole on the front of that print station, observe the present location
of the print line on the print head in relation to the platen roller.

3) As the printer is printing labels use the adjustment thumbscrew to move the head
left and right. Since this adjustment is very precise, do not turn the thumbscrew
more than 1/4 turn before evaluating the results of your adjustment. (See Note)

4) Continue adjusting the thumbscrew until obtaining optimum print quality. Most
stocks and inks print the best with the tangent adjusted to just before top dead
center.

5) Rerun some label to determine if any further adjustment is required, if so repeat
steps three through seven.

NOTE: The print head mounting block is spring mounted so that tangent

adjustment can be performed without loosening mounting screws.

Knife squarness

Stacker

squarness

If the test pattern, printed on a wide web (4" (100mm) plus), is lighter on one edge
than the other, it is possible that the printhead is out of square. This can also be
detected by looking at the front edge of the print head in reference to the printhead
holder. To remedy this problem, power off the machine and remove the print head
as outlined in the print head installation information. The printhead adjustment plate
has been manufactured so when properly adjusted the head will be square. The
printhead holder has a locator plate that must be slide up snug against the printhead
mount plate. Reinstall the head and it should be square to the web.

The knife has an adjustment to square the cut to the stock. To make the adjustment,
loosen the two cap screws, one on top of the knife and one below the knife, using the
3/16" ball driver in the tool kit. Move the knife in the direction desired to square the
cut and retighten the screws.

The stacker has four adjustments that can be made without a tool to accommodate
different types of stocks.

40 • Adjustments

Stock Length Adjustment

Loosen the two thumb screws at the base of the stacker uprights and slide the
uprights to a position that allows the cut tag or label to hang over the last belt roller
approximately 1/4" (6mm). Retighten.

Stock Width Adjustment

Loosen the two thumbscrews behind the stacker uprights and adjust the stacker
upright nearest to the operator to the desired stock width position. Re tighten.

Stacker Angle Adjustment

Loosen the lever located on the side of the stacker assemble nearest the operator and
adjust the angle of the stacker with a few cut labels in the stacker so that there is a
slight gap under the last label as it hangs over the last belt drive roller. Re tighten.

Stacker Full Adjustment

The switch on the inboard stacker up right is used to stop the printer when the stack
is full. A thumb screw adjustment is provided to set the stack height.

Warning: some stock materials can not be stacked to the full height of the

stacker because of excessive weight.

Users Manual Model 676 Adjustments • 41

Machine Set Up Sequence

1) Power off the printer, remove the media and ink and thoroughly clean it from the
unwind to the stacker using alcohol and a clean soft cloth. The print heads should
be cleaned as per the Print Head Cleaning instruction section in the manual.

2) Load a full roll of an average width media and ink on the printer.

3) Power on the printer. After passing diagnostics tests the front panel should display
READY FOR BATCHES if not resolve any remaining error conditions.

4) Arrow down to the PRINT / CUT POSITIONS mode and press enter. Cycle
through all the prints, cut, and station two dot shift values to get a feel for their
present settings.

5) Cycle back to the beginning of the Printer Adjustment and press enter at Print
Checkout Format.

6) Adjust as needed the print head tangent for optimum print quality on all print
stations present. Refer to the Print Head Tangent adjustment section in the
manual. If the machine will not pull stock for this step refer to step number seven.

7) Adjust the feed pressure to pull 11.0" +- .032" of media. Refer to the Feed Roller
Pressure adjustment section in the manual. After the machine is pulling the
correct amount of media, make sure that the tracking line on the back of the label
is at the center of the stock +- .032" through out the label. If it is not, first check
and adjust as needed the unwind, and the collars on the decurler, then if needed
adjust the feed pressure from side to side until it is. Re-verify that the label is

11.0" in length. If the print quality is inadequate refer back to step number six.

8) Using two consecutive labels back to back check the squarness of the cut. Adjust
the knife module, as needed referring to the Knife Square adjustment section in
the manual.

9) Using the front panel adjust the print positions so that the print lines for each print
station present is 1.0" +- .032" from the leading edge of the label.

10) If both stations two and three are present, adjust station number two-dot shift on
the front panel so that the tracking line on the front of the label becomes one
continuous line.

NOTE: Once a production sense mark format is loaded, the cut position may be

adjusted which will cause the print to move accordingly.

The machine is now ready for production formats at which time the operator should

need only to fine tune the prints, cut, and strobes via the front panel.

NOTE: If the machine is used to print on multiple media types the print heads may

need to be adjusted for optimum print quality on each media as they are ran.

Print Head Cleaning

CAUTION: TURN OFF THE POWER TO THE PRINTER BEFORE
STARTING ANY CLEANING.

NEVER REMOVE THE HEAD FROM THE PRINTER EXCEPT FOR
REPLACEMENT.

Supplies:

- Always use clean supplies when cleaning the head.

- Never use anything abrasive to the head.

- NEVER use anything metallic on or near the printhead.

The Anti-static wrist strap (which must contact the skin and be
tight) and anti-static gloves must be worn at all times when
handling a print head to avoid damaging the print head.

- Alcohol and a cotton swab are the recommended items to use when cleaning the

printhead.

RECOMMEND PAXAR "MASTER CLEANING KIT" # 921338

Procedure:

-The Printhead should be cleaned every two to four hours of continuous usage. A

good cleaning of the print head after eight to twelve hours of continuous usage
should be done. This cleaning must be done with the print head in the printer.

- Apply a liberal amount of alcohol to a swab.

- Rub the swab across the print line of the printhead to remove the build-up.

- The platen roller and feed rollers should also be cleaned with alcohol to remove ink

and card dust build-up.

Users Manual Model 676 Maintenance • 43

Clean Platen Roller

You may determine if the printhead has been adjusted properly by performing a test
pattern as documented elsewhere in this manual. A properly adjusted print head will
produce an even grid of chevrons when the test pattern is performed. Before

making any judgments as to the quality of the printhead, it is absolutely
necessary to ensure that the platen roller and the printhead is clean of all
debris. Clean the platen roller located immediately beneath the print head with a

clean cloth and a small amount of alcohol. Be careful not to damage the platen roller
while cleaning. If the roller is worn, replace the roller.

Cleaning Print Sensor

When print registration, in reference to sense mark, becomes inconsistent or erratic
the Sensor and Light Bar may need to be cleaned.

Supplies:

- Always use clean supplies when cleaning the sensor and light bar.

- Never use anything abrasive to the sensor and light bar.

- NEVER use an alcohol based solution when cleaning the sensor or light bar.

- Dry air or a cotton swab are the PAXAR recommended items to use when cleaning

the sensor and light bar.

Print Head Handling

Warning

Print heads can be damaged easily, and are subject to premature failure if not
cleaned on a regular basis. Please follow the procedures carefully to help ensure
print head life and print quality.

Thermal print heads are very sensitive and must be handled with care to help ensure
longer print head life. Because print heads may be damaged through a number of
ways, Paxar has developed the following procedures;

Handling

Static discharge is very detrimental to thermal print heads. To avoid contacting

print heads with a static charge, follow these simple procedures:

- All print heads should be kept in original anti-static bags until they are
placed in the machine.

- The 676 printer is supplied with an anti-static wrist strap. Locate the strap

- it must be worn at all times when handling the print heads.

- Do not touch any terminals extending from the print head or the print line.

- Anti-static gloves are provided with your machine upon installation and
extras may be ordered from Paxar. These gloves must be worn at all
times when handling the print head. If an anti-static glove is not
available, make absolutely certain to thoroughly wash and dry your
hands before handling the print head. Oils from your hands can
contaminate the print line and quickly destroy the printing elements.

44 • Maintenance

Print Head Replacement

NEVER REMOVE THE PRINT HEAD FROM THE PRINTER EXCEPT

FOR REPLACEMENT.

TURN OFF THE POWER TO THE PRINTER BEFORE STARTING ANY

ELECTRONIC COMPONENT REPLACEMENT.

NOTE: The Anti-static wrist strap (which must contact the skin and be tight) and

anti-static gloves must be worn at all times when handling a print head to avoid
damaging the print head.

1) Review the Printhead Handling Procedure Sheet packaged with each print head to
determine if any procedures have changed before beginning this procedure.

2) Remove the media and ink from the machine for easy print head removal.

3) Unplug the cables that connect to the print head. Unplug the cable by firmly, but
gently pulling it out.

4) Loosen the two 6-32 screws on the rear of the print head holder and slide the
mounting pins inward.

5) Place your hand (with static gloves on) underneath the print line of the print head
and push up to release the locator pins on the heat sink, while pulling the print
head to the right of the machine. This will remove the print head assembly from
the mount plate. You may need to "help" the print head out by pushing on the
heat sink with your left hand.

6) Remove the two print head mount screws located on the top of the print head with
a Phillips head screw driver.

7) Remove the old printhead carefully from the heat sink.

8) Place the new print head onto the heat sink. Check to see that the new printhead
sits square on the heat sink and that there is no end play. If there is end play, or
the head does not seat properly, the heat sink guide will need adjustment.

9) Replace the two print head mount screws. Be sure that the head is resting flat on
the heat sink before tightening these screws.

10) Replace the print head assembly in the printer, sliding the pins (Paragraph 4) into
the holes in the mount plate. Make sure that the guide pins insert into both the
front and back grooves. Secure the 6-32 screws.

11) Reconnect the print head cable connectors, making sure that the connectors are
seated tightly.

NOTE: If the cable is not connected correctly, the print head will be destroyed when

the machine is powered on. Check to see that the cable is tight by
observing from underneath the print head. The cable’s connectors should
be inside of the connectors located on the print head.

12) Replace the media and ink and double-check your work. Power the machine on
and make sure that no adverse effects are noted.

Lubrication Procedure

General

The 676 series printers are factory equipped with either composition bearings not
requiring lubrication, pre-lubricated bronze bearings, or pre-lubricated needle
bearings. The one exception is the rub cams on either end of the rotary knife.
Periodic cleaning of the printer and removal of dust will greatly enhance the length
of the time the printer will function.

Cam - Lubrication Procedure

1) Clean dust and residue from cams (using alcohol or other suitable solvent) daily,
or approximately every 100K cuts. Use any good quality general purpose grease
(not oil). Apply with cotton swab or other non-metallic device.

2) If lubrication is omitted, knife will squeak and draw attention to required
lubrication.

3) Some machines are equipped with a self-lubricating oiler system built into the
knife protector. This is an oil-wick system and will require 2-3 drops of SAE 30
weight oil weekly. Be sure wick is in contact with cam. If not, press wick
downward with any suitable blunt device that will fit through the oil cap.

Composition (Iglide) Bearings

1) If field replacement of an assembly fitted with an Iglide bearing is performed, a
single drop of spindle oil should be applied to assist in bearing break-in.

2) If, after long use, an Iglide bearing starts to "squeak", disassemble the component
containing the bearing and lightly abrade the shaft surface. Clean the bearing
(dust or old oil) with alcohol, re lubricate with 1 drop of light oil and reassemble.

No other printer lubrication should be required in normal use.

1. After the clutch and actuator is mounted to the knife, attach the solenoid assembly to the inside

support using two 6-32 x 3/8 cap screws, flat washers, and lock washers. Make sure the plunger
moves freely and does not bind. Motor and faceplate must be mounted also.

2. Check the gap between the actuator and the top of the pin on the clutch as shown in drawing.

The plunger should be pushed in to make the measurement.

Other hints if there is still a problem:

• If the gap is greater then .047”, an old solenoid bracket is being used. Replace (P/N 357003) or

slot the bracket.

• If plunger binds, the solenoid is not parallel with the base of the bracket that mounts to the knife

support, and/or the actuator slot is bottoming out on the roll pins that are on the plunger. Make
adjustment or replace the bracket.

Users Manual Model 676 Appendix D • 67

• Torsion Spring should be at an angle of 60±2°. Lay the spring over the drawing below to see if

the spring is made properly.

• Plunger pins should be centered on shaft. If either pin is loose DO NOT use the plunger. The

pins should be checked before installing.

• (Rev 3) Replace both roll pins on all reworked assemblies.

• (Rev 4) Effective 3/3/97 a large nylon washer will be added between the coil pin and the c-clip

on the plunger. To install, the c-clip has to be removed, then put the large washer on the
plunger and push it down against the coil pin. While holding it in that location, re-install the c­clip. Now the Small nylon washer and spring can be put on the plunger and inserted into the
solenoid.

68 • Appendix D

• There should be a .010-.020 gap (for roller clutch only) between the two clutch pieces.

• (Test on the solenoid test box.) The knife must cut both fabric and card stock. The solenoid

should operate on both the high and low settings.

• Excessive motor drag must be minimal at start/stop and while running. Replace or repair

problem component. On old knife assemblies, there are bronze bushings in outer support. They
may be causing a bind. Ream bushing and retest. (Do not ream if it is a roller bearing.)

• (Rev 1) Pre-load setting adjustment. While motor is running, not while cutting, loosen set

screws on “pac-man” and rotate the rotary blade clockwise, mark the stopping position on the
“pac-man”, rotate counterclockwise, mark the “pac-man”, then rotate the blade to the middle of
the two marks and tighten the set screws.

• (Rev 2) All new knife assemblies have a blue clutch. The clutch outer race bushing has an I.D.

of .500 and the 2 extension springs are .012 dia wire.

• (Rev 2) The 2 extension springs on all rebuilt clutches must have the .009 dia. wire springs

replaced with .012 wire springs.

• (Rev 5) Replace Knife Actuator 357020, if it is worn or if there is a “bulge” at the 90-degree

bend.

• (Rev 6) Changed feeler gauge tolerance from .047 MIN

Printhead Life Extension

NOTE: This section was written specifically for the 636/656 – but the
information is useful and applicable for the 676 as well.

Matching stock and ink widths

If your customer is running multiple media and multiple widths on their Paxar machine, Great! They are
taking advantage of one the most compelling features of our printers: multimedia capability. Our printers can
also reduce the width of the ink to only that area being printed. However, we run into printhead problems
when customers combine both these features.

The edge of the narrower stock not covered by the ink will gouge the printhead and cause dots to be
out.

Printhead

Here, the customer will have
much shorter printhead life
because of the edge of the
narrower, uncovered stock.

WRONG!

The solution is to make sure
that the narrower stocks
have at least 1/8” of ink
coverage over the edge.
The widest stock does not
need full ink coverage.

RIGHT!

This edge which is

not covered by ink

will erode the

printhead.

Printhead Fail Modes

Symptoms, Causes, Solutions

Symptom #1:

A dot is leaving a line in the print direction. The dot appears to be dragging or failed on,

sometimes in the print area, and sometimes not. If in a barcode, the verifier will halt the printer.

Cause: Paper dust or dirt on the printhead
causing the ink to print without printhead firing.
The dot is NOT failed on. The printhead is
DIRTY.

Symptom #3: While printing along fine early in the printheads life (< 300,000 inches), a dot suddenly

appears missing. The verifier will halt the machine if the missing dot is in a barcode.

Cause: Most likely, the printhead failed from static.

Solution: Replace the printhead. Note current life counts on the printer. If less than 500,000 inches, return

for a pro-rated credit.

If problem continues: Check that the machine has all the static upgrades. Double check the connections
and wires.

Printhead Cleaning Procedure

Printhead performance and life are influenced by proper handling and cleaning.

• Dirt on the printhead which causes problems is often too small to see.

• Exercise care in handling printheads as they are very susceptible to static. Use the wrist grounding strap

and anti-static gloves when handling.

• It is OK to scrub the printhead HARD to clean it. Use rubbing alcohol and the “loop side” or “wool side” of

Velcro, followed by drying with rough, brown paper towels.

• If the printhead doesn’t work, take it out and clean it again.

• For maximum printhead life, clean the printhead after every roll change of ink or every 20,000 inches.

In Machine Cleaning Procedure

1. Stop the machine after the last batch has printed to
avoid loosing data.

2. Turn the machine off.

3. Open the printhead carriage assembly.

4. Soak a small amount of rubbing alcohol on a cotton
swab and apply to the printhead.

5. Scrub the printhead several times with hard force
using the “wool side” of Velcro.

6. Dry the printhead with a dry, brown paper towel.

7. Shut the printhead carriage assembly and resume
printing.

8. If a problem continues, remove the printhead and
clean it.

Dirt along the

print line.

Printhead cleaning when removed from the printer

1. Remove the printhead.

2. Place the printhead upside down on the edge of a
clean table with the connector pug over the edge of
the table.

3. Soak a small amount of rubbing alcohol a cotton
swab and apply to the print line.

4. Scrub the printhead several times using HARD
pressure with the “loop side” of Velcro.

5. Dry with a dry, brown paper towel.

6. Replace the printhead.

Static Checks for 636/656 Printers

1. Stacker: With an ohmmeter, check continuity between the main stacker
roller, which has the belts on it, and the chassis ground. Chassis ground
can be any screw near the serial cable. Check that these two important
enhancements are functioning:

a) Check the grounding clip is

installed and making physical
contact with the main stacker
roller. Sometimes, the clip is
installed but moved off the roller.

b) Check the stacker mounting knob has a

3. Printhead static protections. Check for proper installation.

a) Static brushes. Make sure the brushes

are installed and just barely touching the
stock and ink. Too much dragging and
they wear, too little contact and they don’t
dissipate the static.

b) Static shield. Make sure the static shield

is installed and the screws are tight.

Steps for initial set up on a Paxar 636 or 656

1. Software: In Formatter, open the format. From the Format menu, select Attributes. Select the “Ink
Setup” tab. Check that the combination of stock and ink types matches what is running on the machine.

2. Pressure: Open the printhead such that it hangs at an angle.
Loosen the printhead pressure knob enough to that it just
sticks and does not slide from gravity. Position the knob in
the center of the ink. Close the printhead, tighten 3/4 of a turn.

3. Tangent: Set the tangent so that the locking screw is
centered when looking down on the printhead.

4. Strobe: Using the arrow keys, select “Setup” on the front
panel. Using the arrow keys again, select “Strobe”. If not 0,
return the strobe setting to zero using the arrow keys, and
then the “Enter” key.

Printhead Carriage Assembly

5. Ink tension: Back the tension on the ink unwind and take up to minimal. Turn the tension knobs left or
counter-clockwise.

6. Stock widths: The width of the ribbon must be greater than the supply width. Since some supplies are
more abrasive to printheads than others, using a ribbon wider than your supply helps protect the
printhead. Failure to do this may void your warranty. Replacement printheads are expensive.

7. Cleaning: Clean the printhead with an approved printhead cleaning method. Use rubbing alcohol on a
lint free cloth or the “Hook side” or Velcro. Always turnoff the machine and wear the wrist grounding

Platen Rollers for 6x6 and 676 Printers

There are several types of platen rollers made for the 6x6 and the 676 series of
controlled printers. The material printed will determine the color (hardness) of the
roller as well as width of the cut down part of the platen. The green rollers are
harder and used for fabric applications. The red rollers are softer and are used for
tag applications. The rollers are determined by tapes / tags and is not dependant on
the ink selection. The width of the fabric will determine the width of the cut down
part of the green platen roller. The ink should not extend beyond the edge of the cut
down part of the platen. The 1 3/8” roller can be used for fabric from the minimum
1” to 1 1/8” wide. The 3” cut down platen roller can be used from 1 1/8” to 2 ½” in
width. Fabric from 2 ½” wide up to the full 5” width of the printer should use the
regular full size platen rollers.

The following pages will show the platen rollers used in the 6x6 and 676 controlled
printers. They are approximately full size. Just compare the roller you are using to
one of the pictures and using the following chart – select the replacement part
number. The first 6x6 machines had beige colored covers and the web path was
back justified. The later model of 6x6 has gray colored covers and has a web path
that is centered on the platen rollers in the same way as the 676.

Motherboard Power Connectors

The power supply connector on any PC / XT or PC / AT compatible motherboard is made up of dual six-pin male
connectors. Two female connectors from the power supply plug directly onto these male connectors. The following
diagrams illustrates the proper method of attaching the connectors.

Ensure that all of the black wires are located next to each other in the center of the two connectors (as shown in the diagram
below), and that the clamps on the back side of the connectors ate secured along the PCB header. All pins should be covered.

Warning: Connecting the power supply incorrectly may cause irreversible (unwarranted) damage! Ensure that the power is
turned off before connecting the power supply. Make certain that the 115 / 230VAC fuse drawer is in the correct position
