You cannot print color.
Make sure the Color Correction menu item is not set to Black & White.
Make sure the color print units are completely installed in the printer.
Go to
“Transfer belt up down check” on page 2-93
.
Transparencies curl excessively.
Make sure you’re using the recommended Lexmark transparencies. Also
be sure the paper delivery is set to the rear exit.
The printer seems slow to print.
If you set the Paper Type to Transparency or Card Stock, the printer
increases the fuser temperature and slows printing to improve the print
quality. After printing on these media, the printer requires additional time
to cool the fuser after you select another Paper Type setting (such as
Plain Paper or Letterhead).
If Printer Usage is set to Maximum Yield, the printer calibrates the print
head timing. The printer performs this same calibration each time you
turn the printer on and each time you open and close the top cover.
Depending on the types of jobs you print, these adjustments may
significantly slow print time.
If the belt is in the up position for color printing, the printer prints at 30
ppm only.
If the printer is in quick print mode, the printer prints at 17ppm until the
printer is fully warmed up.
You cannot remove paper
jammed in the fuser.
Open the fuser rollers by operating the fuser pressure relief lever. If you
cannot remove the jam, replace the fuser. The jam access panel can also
be opened. After letting the fuser cool, unscrew the two thumbscrew and
open the access panel.
You cannot clear the paper jam
message.
To clear the paper jam messages, you must remove all paper from the
printer paper path. Check both inside the printer as well as the paper
source you were using. Open and close the front cover, and press
Go

the message does not clear, go to
