Using a damp cloth that you have wrung out completely, wipe

on the Platen as a whole (a), the Paper Retainer (b), Border-
less Printing Ink Grooves (c), and Ejection Guide (d).

• Never use flammable solvents such as alcohol, benzene, or thinner. If these substances come into contact
with electrical components inside the printer, there is a risk of fire or electrical shock.
• 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.
Do not touch the Linear Scale (a) or Carriage Shaft (b).

This may stain your hands and damage the printer.
