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.

Cleaning the printhead lenses

1

Open the front door.

Remove all print cartridges.

Warning—Potential Damage: Do not touch the shiny area on the photoconductor drum. Doing so can damage the

photoconductor.

Checking the status of supplies

A message appears on the display when a replacement supply item is needed or when maintenance is required.

Checking the status of supplies from the printer control panel

From the home screen, touch Status/Supplies > View Supplies.

Checking the status of supplies from a network computer

Note: The computer must be connected to the same network as the printer.

1

Type the printer IP address into the address field of your Web browser.
If you do not know the IP address of the printer, you can:

View the IP address on the printer control panel in the TCP/IP section under the Networks/Ports menu.

Print a network setup page or the menu settings pages and locate the IP address in the TCP/IP section.

2

Click Device Status.
The Device Status page appears, displaying a summary of supply levels.

Ordering supplies

To order supplies in the U.S., contact Lexmark at 1-800-539-6275 for information about Lexmark authorized supplies

dealers in your area. In other countries or regions, visit the Lexmark Web Site at www.lexmark.com or contact the

place where you purchased the printer.

Note: All life estimates for printer supplies assume printing on letter- or A4-size plain paper.

Ordering a print cartridge

When 

88 [color] cartridge low

 or 

88 [color] cartridge nearly low

 appears, order a new

cartridge.
Estimated cartridge yield is based on the ISO/IEC 19798 standard. 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.
