This section discusses potential print quality problems, what
causes them, and how to resolve them.
Background is Smeared
Toner can spread where it does not belong when there is too
little toner or when the Belt Cartridge is worn out.
Solutions
•
Check the Toner Module of the color that is smearing.
Replace it if it is too low.
•
Replace the Belt Cartridge if it is worn or has reached the
end of its expected life (about 12 months).
Image Edges are Missing or Peeling
If edges of images are not sharply defined, are peeling, or are
missing, there may not be enough toner or the Belt Cartridge
may be warped.
Solutions
•
Check the Toner Module of the color that is effected.
Redistribute the toner or replace the Toner Module if it is
too low.
•
Replace the Belt Cartridge if it is warped or has reached
the end of its expected life (about 12 months).
Horizontal Jitter
Toner distribution appears uneven horizontally across the
page.
Solution
•
Call a service representative to check the printer.
Horizontal Ribbing
Light print appears in a ribbed pattern at the left or right side
of the page. This may be caused by a tilt in the surface
supporting the printer, or by too little toner.
Solutions
•
Check the table the printer is on. It should not be tilted
more than 1.5%.
•
Check the Toner Modules. Replace any that are too low.
Image Shows Banding, Shadows, or Shifting
This occurs when the image wrinkles, shifts, or color mis-
registers.
Solution
•
Call a service representative to check the printer.
White Line
If a vertical line appears in a specific color area, there may be
paper, dust, or some particle stuck to that color’s Developer
Roller or Toner Module Blade.
Solutions
•
Check the Toner Module of the color that is misprinting.
•
Call a service representative.
Vertical Streaks
A vertical band runs the entire length of the paper.
Solution
•
Clean the Charge Wire at the end of the Belt Cartridge.
•
Call a service representative to check the printer.
Vertical White Band
A white band appears vertically in the print image.
Solution
•
Make sure the Toner Modules have toner.
•
Clean the Laser Lens. See page 84 for procedure.
•
If problem persists call a service representative.
