Troubleshooting 
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 roll cartridge).  
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
page 31 for examples of symptoms, probable causes, and solutions.
