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 rollers, 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 maintenance kit, see the instruction sheet that came with the supply.
