Solving print quality problems
Solution
Marks occur repeatedly only in one color and
multiple times on a page:
Replace the item if the defects occur every
35 mm (1.38 in.) for the toner cartridges.
Marks occur down the page repeatedly in all
colors:
Replace the item if the defects occur every:
• 35 mm (1.38 in.) or 95 mm (3.74 in.) for
the photodeveloper cartridge
• 95 mm (3.74 in.) or 128 mm (5.04 in.) for
the fuser
Turn the printer off. Remove and reinstall the
photodeveloper cartridge. Turn the printer on.
Replace the color toner cartridge causing the line.
If you still have the problem, replace the fuser and
the photodeveloper cartridge.
Clean any spilled toner you see in the printer
housing near the printhead using a soft, clean lint-
free cloth.
See Cleaning the printhead lens on page 52.
