Solving Problems with Printing Quality 183
The print or
color density
is uneven. One or more of the
toner cartridges may
be defective or low. Remove the toner cartridges and
check them for damage. If one is dam-
aged, replace it.
The printer is not
level. Place the printer on a flat, hard, level
surface.
Irregular
print or mot-
tled image
appears. The media is moist
from humidity. Adjust the humidity in the media stor-
age area.
Remove the moist media and replace it
with new, dry media.
Unsupported media
(wrong size, thick-
ness, type, etc.) is
being used. Use KONICA MINOLTA-approved
media. See “Media Specifications” on
page 86.
One or more of the
imaging units may be
defective. Remove the imaging units and check for
damage. If it is damaged, replace it.
There is
insufficient
fusing or the
image
comes off
when
rubbed. The media is moist
from humidity. Remove the moist media and replace it
with new, dry media.
Unsupported media
(wrong size, thick-
ness, type, etc.) is
being used. Use KONICA MINOLTA-approved
media. See “Media Specifications” on
page 86.
Media type is set
incorrectly. When printing envelopes, labels, post-
cards, thick stock, or transparencies,
specify the appropriate media type in
the printer driver.
The levers on the
fuser unit are set to
the position for
envelopes. Before printing on media other than
envelopes, be sure to return the levers
on the fuser unit to the setting for plain
paper.
