Maintaining the printer
Periodically, certain tasks are required to maintain optimum print quality.
Cleaning the exterior of the printer
1Make 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.
2Remove paper from the standard exit bin.
3Dampen 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.
4Wipe 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.
5Make 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.

When 88 Replace Cartridge appears, you must replace the cartridge.
Estimated cartridge yield is based on the ISO/IEC 19798 standard (with about 5% coverage per color). Extremely low
print coverage (less than 1.25%) for extended periods of time may negatively affect actual yield and may cause cartridge
parts to fail prior to exhaustion of toner.
Ordering a photoconductor kit
When 84 Replace photoconductor or 84 Photoconductor low appears, order a new photoconductor kit.
Ordering a maintenance kit
When 80 Routine maintenance needed appears, order a maintenance kit. The maintenance kit contains all
the items necessary to replace the pick rollers, transfer roller, and fuser.
Note: Using certain types of paper may require more frequent replacement of the maintenance kit. The pick rollers,
transfer roller, and fuser can also be individually ordered and replaced as necessary.
Ordering staple cartridges
When Staples Low or Staples Empty appears, order the specified staple cartridge.
For more information, see the illustrations inside the stapler door.

Replacing the photoconductor
You can determine approximately how full the photoconductor is by printing the printer settings configuration sheet.
This helps you decide when you might need to order replacement supplies.
To ensure print quality and to avoid damage to the printer, the printer stops operating after the photoconductor has
reached a maximum of 60,000 pages. The printer automatically notifies you before the photoconductor reaches this
point.
When 84 Replace photoconductor or 84 Photoconductor low appears, order a new photoconductor
immediately. While the printer may continue to function properly after the photoconductor has reached its official
end-of-life, print quality significantly decreases.
To replace the photoconductor:
1Turn the printer off.
2Open the front door.
Note: The photoconductor cannot be pulled out if Side Door A is closed.
