Cleaning
Soiling on the printer head or rubber roller may result in impaired label printing
quality. Use the procedure below to clean the printer head and rubber roller.
Using Cotton Buds
Important!
•
Use a soft implement such as a cotton bud to clean the printer head and
rubber roller. We recommend using the slimmest available cotton buds.
1. Set the printer down on its side and remove the cover.
•
See steps 2-3 in “Installing Tape Cartridges” (Page 20) for information on
how to remove the cover.
•
If a tape cartridge is loaded in the printer, remove it.
Important!
•
Because the printer head is hot during and immediately after printing, wait
sufficient time before removing the tape cartridge.
2. Wipe the surfaces of the printer head and rubber roller clean
with a cotton bud moistened with alcohol.
Wipe the brown section of the printer head that makes contact with the rubber
roller (the area between the dotted lines) particularly firmly.

Cleaning the Exterior of the Printer
•
Use a soft cloth moistened with water to clean the exterior of the printer. Be
sure to completely wring out all excess liquid from the cloth before wiping.
Never use benzene, alcohol, thinners, or other volatile agents, which can
damage the printer.
