Print-Quality Problems
When the print quality is poor, select the closest symptom from the following table and see the
corresponding solution to correct the problem. You can also print test pages to more precisely
determine the print quality problem. See Printing Printer Test Pages on page 178.
If the print quality does not improve after carrying out the appropriate action, contact Xerox Customer
Support or your reseller.
Note: Your printer comes with the option to continue printing even if a toner cartridge is low or out.
You can enable or disable this feature. See the Toner Out Action section in the General Setup Menu
on page 144.
