Maintaining print quality
If you notice a problem with the quality of your prints, the probable solution is
replacing one of the consumable components (Toner Cartridges, Imaging Unit,
Fuser, Fuser Roll, Transfer Kit, or Main Charge Grid).
■If the printer’s front panel message indicates replacing one or more
consumables, replace it if necessary.
■To help you diagnose the problem (in the absence of a front panel message),
print the Consumables Page and Service Print 1 from the front panel’s
Help Pages menu. Refer to “Symptoms and solutions” on page 70 for
examples of symptoms, probable causes, and solutions.
