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.
