Cleaning
Cleaning the Printer Case
When cleaning the printer case, be sure to turn off the printer, and wipe the dirt off the printer case
with a dry or damp cloth.
!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.
Cleaning Inside the Printer
When print quality is deteriorated, clean the paper path (such as the autocutter blade, platen roller,
thermal head, and the roll paper holder).
To clean these parts, turn off the printer, unplug the AC cable, open the roll paper cover, and
remove the paper dust, adherent glue, or other foreign substance with a cotton swab or cloth
moistened with an alcohol solvent (ethanol or IPA).
If paper dust adheres around the black mark sensor, blow or wipe it off to keep the operation of the
printer normal.
For the locations of each part, see the illustration.
!CAUTION:
❏ If adherent glue is attached, be sure to wipe it all off.
❏ Take care not to injure your fingers on the manual cutter when cleaning.
❏ Before turning on the printer after cleaning, allow alcohol on the printer to dry completely.
!KCAUTION:
The thermal head can be very hot after printing. Be careful not to touch it and to let it cool before you
clean it. Do not damage the thermal head by touching it with your fingers or any hard object.
