A single colour is not
uniform or many vertical
streaks (both light and
dark) of slightly differ-
ent density and non-
uniform colour.
The toner is almost depleted.
Replace the colour toner
developer.
Half tone area has areas
of weak colour.
Paper doesn’t match the
environmental conditions, or
it has too much moisture.
Try fresh paper, or another
type of paper.
Store media in the original,
dust-free package in the
same environmental condi-
tions as the printer.
A single colour appears
faded.
The colour density is set
incorrectly in the printer
panel.
Check the density setting by
printing the Colour Calibra-
tion Page in the Colour
Calibration menu from the
printer panel. Compare the
settings with the colour
density samples on the Colour
Calibration Reference and, if
necessary, adjust the density
from the printer panel. Refer
to Setting the Colour Density
on page 31.
The toner is almost depleted.
Replace the colour toner
developer soon (depending on
the complexity of your prints,
you can continue to print up
to 100 more pages).
