Printing quality problems

6. Troubleshooting
Toner specks
• The paper may not meet specifications; for example, the paper may be too moist or rough.
• The transfer roller may be dirty. Clean the inside of your machine.
• The paper path may need cleaning. Contact a service representative.
Dropouts
If faded areas, generally rounded, occur randomly on the page:
• A single sheet of paper may be defective. Try reprinting the job.
• The moisture content of the paper is uneven or the paper has moist spots on its surface. Try a different brand of
paper.
• The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or
brand of paper.
• Change the printer option and try again. Go to
Printing Preferences
, click the
Paper
tab, and set type to
Thick
or
Thicker
(see Basic Guide for paper weights for each sheet).
If these steps do not correct the problem, contact a service representative.
White Spots
If white spots appear on the page:
• The paper is too rough and a lot of dirt from paper falls to the inner components within the machine, so the
transfer roller may be dirty. Clean the inside of your machine.
• The paper path may need cleaning. Clean the inside of your machine.
If these steps do not correct the problem, contact a service representative.
