Safety Issues / Warnings
Caution
This system has some pinch points and hot surfaces. All of these areas have been
well guarded and it is recommended that the safety features of this system are never
altered or defeated.
Heaters
The heat chamber has been designed to prevent the operator from coming into
contact with areas that will cause burns during normal operation. Some surfaces are
very warm to the touch. The IR lamps and internal lamp guards are extremely hot.
Extra care should be taken when threading the machine while the machine is turned
on. Any maintenance or cleaning should be done after the machine has been turned
off and allowed to cool.
Feed Roller
The feed rollers will absorb heat from the web as the machine runs. These rollers
have a self-closing cover to avoid contact during operation. The feed system is also
equipped with an operator knob to advance the fabric forward and backwards as
needed to avoid touching the hot rollers.
CAUTION: TURN OFF THE POWER AND ALLOW THE MACHINE TO COOL
BEFORE CLEANING.

Unpacking / Inventory
Unpacking
The AVERY DENNISON equipment is shipped in a large cardboard box, which may
be difficult to move by hand.
DO NOT REMOVE THE MACHINE FROM THE BOX OR UNPACK IN
THE SHIPPING / RECEIVING DEPARTMENT.
NOTE: Unpacking in the shipping/receiving department is not recommended for the
following reasons.
First: The cardboard carton in which your AVERY DENNISON equipment was
shipped allows the machine to be moved with a forklift, forkcart or
handcart. Because of the weight of the machine, it is easier and safer to
use one of these devices to move the equipment to its intended
installation location.
Second: Leaving the machine in the carton while it is being moved within your
facility will help to protect the equipment during any movements to this
location. Once the equipment has reached its intended location you
should begin the unpacking process.
Open the carton from the top. Do not cut deep into the carton, as there are items
located just under the top. Remove the items located on the top insert. Remove the
top insert. Lift the machine onto the table with the two banding straps. Remove the
two straps and the plastic from the machine. Inspect the machine for shipping
damage. If damage is discovered, contact AVERY DENNISON for further
instructions - in the U.S.A. at (570) 888-6641. In other countries please contact your
local AVERY DENNISON supplier. Once you are satisfied that there was no
obvious shipping damage, the machine can now be moved to its intended location. In
some cases, a double box has been used to ship your machine.

LOKPRINT™ II Assembly
Installation Setup Procedure
1) Assemble the system components and connect all the interface cables between
the three components.
2) Check / set the Printer TCB DIP switches for a 676 with stacker jam disabled (1,
3, and 4 ON / all others OFF).
3) Power on the Printer, Lokprint II, and Finishing Station for warm up.
4) While the Lokprint II Ready light is still off close the Lokprint II and Finishing
Station guards, raise the Finishing Station stacker platform, and check / enter the
value for Calibrate Sensor “Stacker Not Blocked” on the 676. This value should
be somewhere around “40”. Once the ready light comes on check / enter the
value for “Stacker Blocked”. This value should be somewhere around “225”.
5) Load fabric and ink on the Printer, advance the fabric though the Lokprint II.
6) Once all interlocks are satisfied press the start button on the printer to clear any
remaining errors, the front panel should now read “Ready For Batches / Lokprint
II”.
7) Download data to the Printer, this format should include a printed sense mark for
the Finishing Station to register.
8) Press start again and allow the system to run until there are sufficient printed
labels to thread and register in the Finishing Station.
9) Thread the Finishing Station and align the sensor / sense mark for registration.
The sense mark must be the first thing the sensor sees when you start the
Finishing Station.
10) Set the Finishing Station settings on its front panel as needed for the format and
start the Finishing Station in order to remove the slack between the Lokprint II
and the Finishing Station. The Speed adjustment should be set to provide
constant tension on the fabric between the Lokprint II and the Finishing Station
with the least Finishing Station stopping and starting.
11) Start the system, while running take note of the Lokprint II oven position in
relation to the oven insulation strip secured to the Plexiglas guard. The oven
should fully engage the strip squarely from one end of the oven to the other. The
oven position is controlled by a C sensor sensing a metal flag bolted to the back
of the outer oven. Check / adjust the sensor position as needed to cause the oven
to travel to the desired position. The guard insulator strip can be adjusted up or
down as needed by loosening it’s mounting hardware and relocating it
accordingly.
The Lokprint II back cover will need to be removed to make the sensor
adjustment. Do not attempt to run the system with the cover removed, as the
process will over heat for lack of controlled airflow around the oven.
12) Check / adjust both guard switch bales as needed to cause both switches to
trigger only when the guard is closed.
12 •••• LOKPRINT™ II Assembly Users Manual LOKPRINT™ II
13) Once the oven position has been checked / adjusted - run the system and take
note of the fabric position in relation to the oven as it enters the oven. Adjust the
Lokprint II box forward or backwards on the bench in relation to the printer
using the template / mount knob. The web position collars on the 676 are more
for a reference then position. Do not use them to deflect the web, as wrinkling
will occur. Do set them to the web edges after the Lokprint II position has been
adjusted to cause the fabric to flow into the oven centered front to back.
14) Once the Lokprint II position has been checked / adjusted - run the system and
adjust the Finishing Station on the bench forward or backwards in relation to the
Lokprint II box so that the fabric flows straight into the Finishing Station’s web
guides.
15) Using the CALIBRATION PROCEDURE section of IS 561301 Rev 2 or higher
check / adjust U1 and U2 offsets as needed to produce and monitor the exit
temperature at 400° while running stabilized.
Note: Requires AVERY DENNISON Service
16) Using the SP2 ADJUSTMENT PROCEDURE section of IS 561301 Rev 2 or
higher check / adjust U1 SP2 as needed to transition from idle to running without
deforming the fabric or dipping in process temperature.
Note: Requires AVERY DENNISON Service
System Interface Cable Connections
Connect both the 7 and 15 pin cable connectors located on the left side of the
LOKPRINT™ II to the host printer. Connect the 7-pin cable connector located on
the Finishing Station or Cold Knife to the 7-pin receptacle located on the right side of
the LOKPRINT™ II.
Installing the Power Cord
Both the 115V and 230V machines incorporate a quick disconnect power cord. The
115V cord requires a NEMA 5-20R receptacle while the 230V cord requires a
NEMA 6-15R receptacle. Install the receptacle end of the power cord in the plug on
the back of the machine then insert the plug end of the cord in the appropriate wall
outlet.

Product Description
Theory of Operation
The LOKPRINT™ II was designed to receive labels printed on both sides from a
AVERY DENNISON 676 printer or one sided from a AVERY DENNISON 636
printer using dye sublimation inks. The LOKPRINT™ II dye sublimates the labels
and feeds a Finishing Station for ultrasonic or cold knife cutting. The LOKPRINT™
II is equipped with four infrared (IR) quartz heating bulbs and two non-contact IR
heat sensors with one PID controller controlling the process and a second monitoring
the fabric temperature. The PID controller controls an SCR that regulates the energy
provided to the quartz bulbs, which produces the heat. The PID control, IR sensor,
SCR, and quartz bulbs are all part of an automatic, “closed loop” system to ensure
fully sublimated labels.
Once connected, all components of the LOKPRINT™ II act as a system, including
the Printer, LOKPRINT™ II and the Finishing Station. Optimum dye sublimation
occurs between the temperatures of 400° - 420° F (205° - 215.5° C) inside the heat
chamber. The LOKPRINT™ II will shut the printer down if the web temperature
drops below 400° F (205° C). This closed loop system approach ensures maximum
sublimation and minimum label waste.
Description of Operation
Hands free operation
Once the LOKPRINT™ II has been threaded, very little operator input is needed. As
the fabric moves through the heat chamber - the PID controllers control and monitor
the web temperature according to web speed. The LOKPRINT™ II is threaded with
the heat chamber in a parked (back) position. When the printer’s start button is
pushed, the heat chamber will move forward to the operating position that covers the
web - heating it to the desired temperature.
If the “stop” button on the printer is pushed or if the system shuts down
automatically, the heat chamber will move back to the parked position.
Interlocks
During operation, the LOKPRINT™ II will shut down the system automatically, if
one or more of the following conditions exist. See the Printer and or Finishing
Station manuals for their interlocks.
(1) Power lost to the LOKPRINT™ II.
(2) LOKPRINT™ II power switchable circuit breaker exceeds safe
current or temperature levels.
(3) Oven didn’t reach the operating position in time at startup.
(4) No web in web sensor.
(5) Heat chamber thermostat temperature exceeds safe limit.
14 •••• Product Description Users Manual LOKPRINT™ II
(6) Web under temperature alarm.
(7) Oven over temperature alarm.
(8) Guard open.
The recommended room temperature for the system is 60°F (15.5°C) to 90°F
(32.2°C). If a cooling system is required it should not be pointed directly at the
system to create drafts that could affect the sublimation process.

JAM SENSOR
Jam Sensor
The jam sensor (illustrated with the bridge removed) is looking for the presence of
the fabric for the printer to start and continue to operate. If the fabric in not present,
the system will not start and the printer front panel will display a message “Check
Stacker”. If the fabric breaks during operation and pulls out of the sensor, the system
will stop and printer front panel will again display “Check Stacker”. If the web sags
more than the feed can take up before the heat chamber moves to the run position, the
web may be pushed out of the jam sensor and stop the system.

VAPOR FILTER
SNAP ON COVER
Ventilation
The LOKPRINT™ II is equipped with a ventilation system comprising of two fans
with carbon filters and multiple internal machine compartments / components. One
filter is used to reduce the odors that are exhausted from the heat chamber while the
other is used to filter the ambient air drawn in to cool the electronics compartment.
Vapors created during the sublimation process have an odor and may be seen as
smoke escaping from the heat chamber area. If there is an unusually high amount of
odor or visual smoke escaping near the front of the machine - check the filter(s) on
the back of the machine. Make sure they are in place and clean. The filters are held
in place with a snap on cover for quick and easy replacement.
The exhaust fan’s filter (on the right as viewed from the rear of the machine) will
normally need to be turned over after every 2 rolls of ink and replaced after
approximately 4 rolls of ink. At the time of replacement it is recommended to move
the intake fan’s filter to the exhaust fan and install a new filter on the intake fan. This
rotation procedure will insure that both filters are kept at peak performance.
As the system pulls fresh air in the front of the heat chamber and exhausts it out the
filter - it also cools the outer surfaces of the machine so they are safe to the touch.
These surfaces will be warm to the touch, but will not cause burns.
It is extremely important to keep the Plexiglas guard closed at all times during
operation except for threading the fabric. The airflow management and heat chamber
control systems have both been designed to operate with the guard closed and all the
covers in place. Attempting to operate the system with any guard or cover altered or
missing will disrupt the control strategies and adversely affect the fabric temperature.

Web Threading
Feed Roller
The feed roller has two torsion springs that supply even tension for tracking. If the
fabric fails to track properly through printer, check to see if one of the springs have
come loose, broken or been stretched out of shape. The feed is equipped with a hand
knob used to thread the machine. This knob should turn freely with very little
resistance. If resistance occurs, check to see if the roller bearings need to be greased
/ replaced. Use standard multi purpose grease to lubricate the bearings. To lubricate
the bearings - the assembly will need to be disassembled, cleaned and repacked with
grease. Do not use contact cleaners to clean the bearings, as this will destroy the
needle bearings.
Feed the fabric through the AVERY DENNISON 676 or 636 printer (see the
AVERY DENNISON 676 or 636 manual for threading instructions), then through the
LOKPRINT™ II and on through the Finishing Station or Cold Knife Cutter. Tension
the web with the feed knob to remove excess slack between the printer feed rollers
and the LOKPRINT™ II feed rollers. The system will further tension the web at the
start of printing, but may not take out excessive web sag.
