Printer maintenance kit
Note The printer maintenance kit is a consumable and is not covered under warranty.
To ensure optimum print quality, HP ecommends that a new printer maintenance kit be installed
approximately every 350,000 pages to ensure print quality. Depending on how you use the MFP,
you might need to replace the kit more often. If you have questions about how frequently you
should replace the printer maintenance kit, contact the support center at www.hp.com/support/
lj9040mfp or www.hp.com/support/lj9050mfp.
When the PERFORM PRINTER MAINTENANCE message appears on the control panel, you need to
purchase a printer maintenance kit and install the new parts. The part number for the 110-V kit is
C9152A. The part number for the 220-V kit is C9153A. (See Parts and accessories for ordering
information). The printer maintenance kit contains two Type 1 rollers, seven Type 2 rollers, one
transfer roller assembly, and one fuser assembly. Complete instructions for installing the kit
components are included in the printer maintenance kit box.
