White Spots
• 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.
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.
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.
