We recommend that you clean the printer at least once a month to keep it in good
working condition and to maintain print quality.
Turn off the printer and disconnect the power cord from the AC outlet before cleaning the
printer. Failure to turn off the printer and disconnect the power cord may result in electric
shock.
Cleaning Precautions
• Never spray anything directly onto the printer. Droplets can enter the printer and
cause malfunctions. Never use detergents other than neutral detergents.
• Never lubricate the printer with oil. The printer does not require lubrication.
• Never use a vacuum cleaner to clean the printer.
Cleaning the outside of the printer
1.
On the printer's right side, press the
side of the power switch marked [O] to
turn off the printer.
2.
Use a soft, damp, well-squeezed cloth
to clean the outside of the printer.
If some stains prove difficult to remove,
use a cloth lightly moistened with
neutral detergent.
3.
Wipe any remaining water with a soft,
dry cloth.
