When Cartridge low appears, you may need to order a new toner cartridge. You may be able to print a limited number of
pages when the message first appears, but it is best to have the new cartridge available when the current one runs out.
Ordering a toner cartridge
Notes:
• The estimated cartridge yield is based on approximately 5% coverage per page.
• Extremely low print coverage for extended periods of time may negatively affect actual yield.

Ordering a maintenance kit
To identify the supported fuser type, view the label on the fuser. Do either of the following:
• Remove the toner cartridge and imaging unit. The two-digit fuser type code (such as 00 or 01) can be seen on the front of
the fuser.
Warning—Potential Damage: Do not expose the imaging unit to direct light for more than 10 minutes. Extended
exposure to light may cause print quality problems.
• Pull down the printer rear door. The two-digit fuser type code (such as 00 or 01) can be seen on the rear of the fuser.
Notes:
• Using certain types of paper may require more frequent replacement of the maintenance kit.
• The separator roller, fuser, pick roller assembly, and transfer roller are all included in the maintenance kit and can be
individually ordered and replaced if necessary.
• For more information on replacing the parts included in the maintenance kit, see the instruction sheet that came with the
part.
