Replacing a Thermal

Printer Ribbon

When the ribbon roll runs out install a new roll to replace it. Each new

ribbon roll has a long leader to thread through the labeler. Follow the

procedure below to install the new ribbon (refer to Figure 5-25).

1. Prepare the ribbon threading path by pushing the ribbon pinch roller

to the right.

2. Install the ribbon take-up core (one empty core is supplied with the

printer) on the ribbon take-up hub. After threading the ribbon, you

will tape the ribbon’s leader to this cardboard core.

3. Thread the ribbon leader over the ribbon alignment roller 1, over the

print head, and over ribbon alignment roller 2.

4. Thread the ribbon leader under the ribbon drive roller, over the

ribbon pinch roller, and down to the ribbon take-up roll (see Figure

5-25).

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.
