Cleaning the Printer’s Exterior
Should the outside of the printer become dirty, clean it using a
soft cloth moistened with water. If necessary, add a very small
amount of a mild soap such as a liquid dishwashing detergent.
CAUTION: Avoid saturating the cloth. Do not
allow water to get
inside the printer.
Avoid the use of benzene, alcohol, paint thinner, or
cleaners that are abrasive, alkaline, or acidic. Such
cleaners may damage the printer’s case.
