- Do not dry the interiors of the upper cover with a dry cloth. Electrostatic charges could make the internal components susceptible to dirt, resulting in degraded
print quality.
- Do not use flammable solvents, such as thinner and benzine, on the printer. Solvents coming into contact with any electrical parts inside the printer could result
in fires or electrical shock hazards.
- Do not touch linear scale [1] and carriage shaft [2].
MEMO:
When cleaning between the Platen and Output Guide, use a damp cloth that you have wrung out completely to wipe over the ejection slot and along grooves.
