Solving 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 a Demo Page to more precisely
determine the print-quality problem. For details, see

Information Pages

on page 22.

If the print quality does not improve after carrying out the appropriate action, contact your Xerox
representative.

Notes:



To enhance print quality, toner cartridges for many models of equipment have been designed to
cease functioning at a predetermined point.



Grayscale images printed with the composite black setting increment the color pages counter,
because color consumables are used. Composite black is the default setting on most printers.
