Service Manual
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 the "Transfer Belt Up/Down Service Check" on
page 2-89.
Make sure you're using the recommended Lexmark
transparencies. Also be sure the paper delivery is set to
the rear exit.
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.
Open the fuser rollers by operating the fuser pressure
relief lever. If you cannot remove the jam, replace the
fuser.
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.
