Using a damp cloth that you have wrung out com-
pletely, wipe away dirt or paper dust (debris from
cutting) inside the Top Cover.
Wipe away any ink residue and paper dust (debris
from cutting) on the Top Cover Roller (a), all over
the Platen (b), the Paper Retainer (c), the Border-
less Printing Ink Grooves (d), the Ejection Guide
(e), the blue Switch (f), the section around the right-
side Borderless Printing Ink Grooves (g), and so

•
Never use flammable solvents such as alcohol, benzene, or thinner. If these substances come into con-
tact with electrical components inside the printer, there is a risk of fire or electrical shock.
Warning
•
Do not use a dry cloth to wipe inside the Top Cover. This may create a static charge, which may attract
dust and affect the printing quality.
Important
•
Do not touch the clear sheet on the side of the Top Cover Roller. This may damage the roller.
