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 printing quality for an
extended period of time.
Cleaning Thermal Head/Platen/Rubber Feet (Front Paper Eject Model)
(1) Turn off the printer.
(2) Unplug the AC plug of the AC cable from the outlet.
(3) Open the paper cover.
(4) Clean the thermal head, the platen and/or the rubber feet with a cotton swab with a small amount of
ethyl alcohol.
(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.
◆
DO NOT touch the gear of the platen. Doing so may cause loss of printing quality or a
failure.
◆
The rubber feet have the special adsorption structure. They lose adsorption force as
dust or dirt adheres. However, it can be recovered by cleaning.
