Irregular, raised spots or stray toner
Problem
Solution
Toner is smudged on the back of pages.
Toner collected on the transfer belt can cause
smudging on the back of a page. Smudges
commonly appear on the edges of pages after
media size is changed. The belt is self-
cleaning and the smudging will normally clear
within a few pages. Print 5 to 10 pages to clear
the smudge.
The printer recently had a media jam or the
printer fed multiple sheets of media.
Print 5 to 10 pages to clear any smearing.
Toner is smeared on the edge of the media.
Toner on the edge of the media is usually
caused by toner collecting on paper guides.
Inspect the paper guides and clean with a lint-
free cloth if necessary.
You are refeeding paper that has already
passed through the printer or through a copier.
Do not re-feed paper. Re-feeding paper
contaminates the fuser, causing stray toner
defects.
The fuser roller is dirty.
Print 5 to 10 pages to clean the fuser roller.
Banding
Problem
Solution
Dark and light bands appear in large areas of
halftone areas.
If the problem persists, the imaging drum may
be past its useful life. Print a configuration
page to verify the remaining life of the imaging
drum. Replace the imaging drum if necessary.
Consumable items may be beyond their useful
life.
Print a configuration page to verify the
remaining life of the consumable item. Replace
any consumable items that are past their rated
life.
Certain halftone patterns exaggerate banding. Try a different halftone pattern.
