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.
