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 29.
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.
Symptom Probable Causes Solutions
Faded printouts with multiple
colors faded.
The toner cartridges are not
Xerox
®
toner cartridges.
Verify that the toner cartridges meet
specifications, and replace them if necessary.
The paper being used is outside
the recommended specification
range.
Replace the paper with a recommended size
and type, and confirm that your control panel
and print driver settings are correct. For
details, see Supported Paper on page 118.
The paper type is heavier or
thicker than the paper type
selection.
• Ensure that the proper paper is loaded in
the paper tray.
• Choose a heavier paper type at the
control panel and in the print driver.
• Use a lighter paper or paper type.
The bias transfer voltage is not
properly adjusted for the paper
type.
Verify that the paper types set in the control
panel and the print driver match the paper
loaded in the tray.
The settings in the application or
print driver are incorrect.
Print the Demo Page from the Information
Pages menu. If the Demo Page looks correct,
the printer is printing properly. Your
application or incorrect settings in the print
driver are probably causing the print-quality
problems.
The paper is damp. Replace the paper.
The high-voltage supply is
defective.
