Solving Print-Quality Problems
When the print quality is poor, select the closest symptom from the following table and refer to the
corresponding solution to correct the problem. You can also print a Demonstration Print page to more
precisely determine the print-quality problem. For details, refer to Information Pages on page 28.
If the print quality does not improve after performing the appropriate action, contact your
Xerox representative.
Notes:
• To maintain print quality, the toner or drum cartridges for many models of equipment are
designed to stop 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.
