Colors missing
See chapter 2, “Printing” of the user’s guide for information on
optimizing color output.
If colors are missing, make sure that any newly installed toner
and developer cartridges are properly installed, with the sealing
tapes removed. Review the steps in “Replacing a Toner Car-
tridge” and “Replacing a Developer Cartridge” in chapter 3,
“Maintenance.”

Light Image (Entire Page)
Increase the print density for any color(s) used on the page (“Print
Density Problems” on page 14 for details).
Remove each toner cartridge for a color used on that page, and
shake it as you do before installing a new cartridge. Then, rein-
stall the cartridge.
Install a new toner cartridge if necessary. (See “Replacing a
Toner Cartridge” in chapter 3, “Maintenance,” for details.)

Light Image on the Left or Right Side of the Page (all colors)
Make sure the printer is level. (By “level” we mean the surface the
printer’s on should be so flat–1° of slant or less–that you can lay a
round pencil down on it and it doesn’t roll in any direction.)
n
Dark Image (Entire Page)
Decrease the print density for any color(s) used on the page (see
“Print Density Problems” on page 14).
Install a new cartridge if necessary. (See “Replacing a Toner Car-
tridge” in chapter 3, “Maintenance,” for details.) The old cartridge
may be defective, releasing too much toner.

Blurry Images, Scratches, or Missing Dots
Make sure the media is in good shape and meets all the specifi-
cations in chapter 2, “Printing.”
Make sure the paper path is clean. See chapter 3, “Maintenance,”
for details on cleaning the charger unit, various rollers, and
plates.
