Cleaning the Printer
Cleaning the Printer Case
Be sure to turn off the printer, and wipe the dirt off the printer case with a dry cloth or a damp cloth. Be sure to
unplug the AC cable while cleaning.
CAUTION
Cleaning the Thermal Head/Platen Roller
It is recommended to clean the thermal head periodically (generally every 3 months) to maintain receipt print
quality.
Depending on the roll paper used, paper dust may stick to the platen roller and the paper may not be fed
correctly. To remove the paper dust, clean the platen roller.
Turn off the printer, open the roll paper cover, and clean the thermal elements of the thermal head/platen roller
with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
CAUTION
Never clean the product with alcohol, benzine, thinner, or other such solvents.
Doing so may damage or break the parts made of plastic and rubber.
• After printing, the thermal head and its surroundings can be very hot. Do not touch it and
let it cool before you clean it.
• Do not damage the thermal head by touching it with your fingers or any hard object.
