Customer Responsibility

Location of Printer

The printer weighs approximately 250 Lbs (113.4 Kg) and requires a table of
sufficient quality and strength to handle this load while the printer is operating.
AVERY DENNISON recommends an industrial type worktable having the
approximate dimensions of 96" (245.8cm) wide to 30" (76.2Ccm) deep to 32"
(81.3cm) high. Refer to Figure 2.

Figure 2 - Recommended Workstation Layout.

The location of the AVERY DENNISON 676 LKP 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. AVERY DENNISON
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 AVERY DENNISON 676 LKP printer is a high-resolution 300 DPI thermal
printer. While AVERY DENNISON 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 AVERY DENNISON 676 LKP printer is designed to operate in conjunction
with the AVERY DENNISON Lokprint™ II box and either an Ultrasonic Finisher, a
Cold Knife Finisher or a Rewind Unit.

User Manual Model 676 LOKPRINT® Customer Responsibility •••• 7

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

8 •••• Customer Responsibility User Manual Model 676 LOKPRINT®

AC Power Line

AVERY DENNISON 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 AVERY DENNISON printer or
peripheral equipment connected to a AVERY DENNISON printer should follow
standard electrical code practices including proper grounding and neutral
requirements.

The AVERY DENNISON 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, AVERY DENNISON recommends that a
separate “clean” service be installed or reserved for the exclusive use of the AVERY
DENNISON printer and it’s peripherals.

Printer Unpacking / Installation

Unpacking

The AVERY DENNISON printer is shipped in a large cardboard box that may be
difficult to move by hand.

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

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

the following reasons.

First: The box in which your AVERY DENNISON printer was shipped allows the

printer to be moved with a forklift, forkcart or handcart. 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 box from top by removing the two (2) banding straps and cutting the tape
seam on top of the printer. (See Figure 3).

Remove the plastic over the printer.

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

There is a sleeve to lift the printer from the box for easy removal.

Lift the printer onto the table.

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. AVERY DENNISON 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 ordered from AVERY DENNISON (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 AVERY DENNISON family of printers is covered in
separate documentation. The “Formatter” software to create formats for the AVERY
DENNISON 676 printer is a Windows application. The original software “Selfform”
will not create formats for the 676. The new "PCMate" package is capable of making
formats for all AVERY DENNISON control printers.

PCMate Plus Ver. 3.21.32 will support the 676LKP. Lower versions may not contain
the test drivers.

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

Loading Stock For The First Time

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 with the outer guide
contacting the roll. Turn the knob an additional ½ turn clockwise. This will
activate the constant backpressure device.

2) Adjust the web guides 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 print heads that are in use by pulling the release knob and then rotating
the print heads into the open latched position. The print stations have a pin in
the rear to hold them open.

User Manual Model 676 LOKPRINT® Printer Operation •••• 13

Butt Splice

6) Open the feed rollers by rotating the feed pressure knob counterclockwise.

7) After looping the leading edge of the stock over the decurler slide it through the
web guides. Keep the stock in the center, as the printer is center justified.

8) As the stock exits the web guides, 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.

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

11) Allow feed to close (spring loaded). Close the printheads that are in use. Do not
run a station closed that is not in use. This will cause premature head failure.

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 AVERY DENNISON 676 LKP has been designed keeping the operators need to
change supplies quickly and often in mind. Re threading the stock is quicker than
butt splicing is. 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 the 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 AVERY DENNISON 676 LKP 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 require 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

14 •••• Printer Operation User Manual Model 676 LOKPRINT®

with the outer guide contacting the roll. Turn the knob an additional ½ turn
clockwise. This will activate the constant backpressure device.

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 slide
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 5). 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.

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.

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.
This roller is mounted in an extension spring controlled arm so no pressure
adjustment is required.

Sensors

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. AVERY DENNISON stocks
are fastened to the supply core and will lift the core at the end of the roll. Supplies
that do not have this feature will fail to stop the printer.

Ink Out

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

Feed Open

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.

Sensor Adjustments:

All the micro switches and optical sensors in your 676 LKP 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 bail is adjusted by carefully bending it as needed.

32 •••• Adjustments User Manual Model 676 LOKPRINT®

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 bail is adjusted by carefully bending it as needed.

Machine Set Up Sequence

1) Power off the printer, remove the media and ink and thoroughly clean it from the
unwind to the stock exit 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 then 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) If all three print stations or stations two and three are present, adjust station
number two by moving the dots with the dot shift on the front panel so that the
tracking line on the front of the label becomes one continuous line.

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

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

- NEVER use anything metallic on or near the printhead.

STARTING ANY CLEANING.

REPLACEMENT.

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 AVERY DENNISON "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.

34 •••• Maintenance User Manual Model 676 LOKPRINT®

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 are 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.

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 AVERY DENNISON 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, AVERY DENNISON 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 LKP 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 AVERY DENNISON. 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.

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 (2) 6-32 Phillips screws visible through holes in the upper print head
holder. Slide the head toward unwind end of printer.

NOTE: Screws are fitted with washers.

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. Periodic cleaning of the printer and removal of dust will greatly enhance
the length of the time the printer will function.

Composition (Iglide) Bearings

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

2) If, after long use, a plastic 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.

Printhead Life Extension

NOTE: This section was written specifically for the 636 / 656 – but the

information is useful and applicable for the 676 series printers.

Matching stock and ink widths

If your customer is running multiple media and multiple widths on their AVERY DENNISON 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.

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

Printhead

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.

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.

If not addressed immediately: the line will go
from black or gray to white and the dot will fail.
The printhead will be damaged.

Solution: Immediately stop the printer and clean the printhead in the machine.

If problem continues: Remove the printhead and clean with hard pressure.

Printhead Cleaning Procedure

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

• Dirt on the printhead that 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.

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
