16. PRINTER MAINTENANCE
The thermal head of the printer does not require user maintenance.
When paper powder accumulates, cleaning the thermal head can maintain the print quality for an
extended period of time.
Cleaning Thermal Head / Platen
1. Turn off the printer.
2. Remove the battery pack from the printer.
3. Open the paper cover.
4. Clean the thermal head and/or the platen with a cotton swab moistened with a small amount of
ethyl alcohol. (See Figure 16-1.)
Figure 16-1 Cleaning Thermal Head / Platen
5.
Wait until any ethyl alcohol remaining on the thermal head and the platen dries out completely, and
then close the paper cover.
NOTE
◆
Clean the thermal head after it cools down.
◆
Be sure to wipe the thermal head with a cotton swab or other soft material.
◆
The printer has 2 paper cutters on the paper outlet: one is on the printer side, and the
other is on the paper cover side. Be careful not to cut your fingers by the paper cutters
during cleaning.
◆
DO NOT touch the gear of the platen. Doing so may cause loss of printing quality or
damage.
