5. Guide the pinch roller back into its operating position against the
drive roller.
6. Use the tape supplied on the end of the leader (or a DIP label) to
attach the leader to the take-up cardboard core.
7. When you install a new ribbon, remove the old ribbon’s cardboard
core and install it on the take-up hub as the new ribbon take-up core.
8. Turn the ribbon take-up roll counterclockwise to advance the ribbon
until it (not the leader) is between the print head and the platen.
Repairing a Torn
Thermal Printer
Ribbon
Under normal circumstances you should not have a problem with the
ribbon tearing. If it does tear, follow the procedure below to repair it.
1. Cut the end of the ribbon to remove the tear and create a straight end.
2. Cut about 16 inches (40 cm) of old label liner (hanging from the label
drive roller) to use as ribbon leader.
3. Line up the end of the ribbon with the end of the liner and tape the
two ends together (a DIP label can also be used as a tape splice).
4. Turn the splice over and tape the other side.
5. Wrap the liner around the ribbon roll once, and then follow the
instructions for installing a new ribbon. If the ribbon begins to slide
off the roll while you are threading, place a large label across the edge
of the ribbon roll to stop the unraveling. Remove this label when you
have finished threading and before you start processing devices.

Cleaning Guidelines
Cleaning the Beam
Follow the steps below to clean and lubricate the beam.
CAUTION: This procedure should be performed only by a qualified
service technician or by the system administrator.
1. Turn off the 2500 and remove the power cord.
2. With a clean, dry cloth, wipe the center connecting rod and the two
outer beam guide posts until no lubricant or dirt remains.
3. With the beam raised, place a drop of TriFlow lubricant on the lower
part of each of the two outer beam guide posts.
4. With the beam lowered, place a drop of TriFlow lubricant on the
upper part of each of the two outer beam guide posts.
5. Move the beam down and up, in a plunging motion, so the lubricant
spreads evenly along the outer beam guide posts.
6. With a clean cloth, wipe excess lubricant from the outer beam guide
posts.
Replacing the Beam Filter
Follow the steps below to replace the beam filter.
CAUTION: This procedure should be performed only by a qualified
service technician or by the system administrator.
1. Turn off the 2500 and remove the power cord.
2. Remove the two thumb-screws on either side of the clear-plastic
beam filter cover plate.
3. Remove the beam filter cover plate.
4. Use needle-nose pliers to remove the beam filter. Examine the beam
filter and replace it if it is dirty or wet.
Cleaning Programming
Module Contacts
It is extremely important to keep the programming modules clean to
extend the life of the contacts. To clean the modules at the appropriate
intervals, as described below, you must
keep an ongoing record
of the
number of device insertions for each programming module. One method
of logging the number of devices that have been programmed is to use
TaskLink’s Session Data Logging feature. This option logs all TaskLink
operations and records the results in a file on your PC, thereby tracking the
number of devices programmed on the 2500.
Follow the procedure below to thoroughly clean the programming
module contacts after every 10,000 devices (which is weekly if you
process 40,000 devices per month on the module). Perform the procedure
more often if you experience continuity-related programming problems.
If you notice debris in the programming module at any time while
running devices in a job, press
STOP
and clean the module with
compressed air. You can then press
START
to continue running the job.

Follow the steps below to clean the PLCC module’s contacts.
CAUTION: This procedure should be performed only by a qualified
service technician or by the system administrator.
1. Blow compressed air into the top of the programming module to
remove any device package debris. Use a rotating motion with the air
nozzle to ensure that you reach all areas.
2. Use the DeoxIT pen to apply conditioner directly to the module’s
contacts. From the base of each contact, draw the pen’s tip up the
length of each contact.
3. Crumple a small amount of soft lint-free cloth, and push it into the
programming module.
4. Install a chuck in the beam, and move it over the programming
station.
5. Set a device, oriented correctly, on the programming module.
6. Move the beam down and up (in a plunging motion) so the device
presses the cloth in the programming module along the full length of
the contacts. Pull on the cloth to lift the device out of the module.
Repeat this process several times.
7. Carefully remove the cloth.
8. With a new cloth, clean the inside of the module (as described in
steps 2 through 5). Repeat the process until the cloth comes out clean
and all the residue is gone.
9. Blow compressed air into the programming module again to remove
any conditioner that has accumulated at low points.
Note: To prevent the first few devices from sticking to the track, be sure to
complete step 9.
10. Insert a clean portion of the cloth into the module to remove any
residual conditioner that may have collected after blowing with the
compressed air.
