Cleaning the Outside of the Printer
You can clean the outside of the printer with a soft, damp, cloth. You can use a cloth moistened
with a mild neutral detergent to remove stains; do not spray detergent directly onto the printer.

To prevent electric shock, turn the printer off and unplug the power cord from the
electrical outlet before cleaning the printer.
Do not use a vacuum cleaner to clean the printer. Do not lubricate the printer with oil.
