White Spots
Vertical lines
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 (see "Opening
Printing Preferences" on page 52).
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 (see "Cleaning the machine" on page 76).
• The paper path may need cleaning. Clean the inside of your machine (see "Cleaning the machine" on page 76).
If these steps do not correct the problem, contact a service representative.
If black vertical streaks appear on the page:
• The surface (drum part) of the toner cartridge inside the machine has probably been scratched. Remove the toner cartridge and
install a new one (see "Toner cartridge" on page 72).
If white vertical streaks appear on the page:
• The surface of the LSU part inside the machine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page
76). If these steps do not correct the problem, contact a service representative.
