Maintaining the printer
Periodically, certain tasks are required to maintain optimum print quality.
Cleaning the exterior of the printer
1 Make sure that the printer is turned off and unplugged from the wall outlet.
CAUTION—SHOCK HAZARD: To avoid the risk of electric shock when cleaning the exterior of the printer,
unplug the power cord from the wall outlet and disconnect all cables to the printer before proceeding.
2 Remove paper from the standard exit bin.
3 Dampen a clean, lint-free cloth with water.
Warning—Potential Damage: Do not use household cleaners or detergents, as they may damage the finish of
the printer.
4 Wipe only the outside of the printer, making sure to include the standard exit bin.
Warning—Potential Damage: Using a damp cloth to clean the interior may cause damage to your printer.
5 Make sure the paper support and standard exit bin are dry before beginning a new print job.
Storing supplies
Choose a cool, clean storage area for the printer supplies. Store supplies right side up in their original packing until
you are ready to use them.
Do not expose supplies to:
Direct sunlight
Temperatures above 35°C (95°F)
High humidity above 80%
Salty air
Corrosive gases
Heavy dust
Conserving supplies
There are some settings you can change from the printer control panel that will help you conserve toner and paper.
For more information, see “Supplies menu,” “Quality menu,” and “Finishing menu.”
If you need to print several copies, you can conserve supplies by printing the first copy and checking it for accuracy
before printing the remaining copies.
