I. CLEANING THE DRIVE ROLLER
The printerÕs Drive Roller should be cleaned during every ribbon change or after
every 250 prints. This helps prevent jams and maintain uninterrupted service. Also
perform this procedure if the roller is visibly dirty. Use the following steps to clean
the roller:
1. Leave the printer power ON, and open the printerÕs Top Cover.
2. Remove the ribbon.
3. Locate the Drive Roller.
4. Use a Cleaning Pad from the Printer Cleaning Kit or a soft, lint-free cloth
slightly moistened with isopropyl alcohol to wipe the roller clean. Press the
On/Cancel and Pause/Resume buttons to move the roller back and forth while
cleaning.
5. After the roller is clean and completely dry, replace the ribbon and close the
printerÕs cover.
