Troubleshooting Phaser 750 Printers
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
Front panel messages
on page 117 for examples of symptoms, probable causes, and
