used.

feeding mechanism.

specifications.
• A recent paper jam may have
contaminated the paper path. Print several
sheets of paper through the printer to help
clear the paper path.

need replacing.

Solution Problem
Smeared Image If the page is easily smeared:
• Clean the inside of the printer.
• Check the paper type and quality.
• The toner may be unevenly distributed
inside the Toner Cartridge. Remove the
Toner Cartridge and redistribute the toner.
• Check the Toner Cartridge for damage.
White Streak If a vertical white streak appears on the page:
• The toner supply may be low. You may be
able to temporarily extend the Toner
Cartridge life by redistributing the toner.
• The Toner Cartridge may be defective.
Remove the cartridge and check for
damage.
• Replace the Toner Cartridge if it is worn or
has reached the end of its expected life.
• If the whole page is light, the print solution
setting is too light or Toner Save Mode
may be on. Adjust the print resolution and
Toner Save Mode with the printer
properties.
• A combination of faded and smeared
defects may indicate that the Toner
Cartridge needs cleaning.
Black Lines
If black or white vertical streaks appear on
the page:
• Try wiping inside the Toner Cartridge area
and laser scanner unit lens. See page 63.
• The photosensitive drum inside the Toner
Cartridge has probably been scratched.
Install new Toner Cartridge.
• The Toner Cartridge may be defective.
Remove the cartridge and check for
damage.
