Solving printing problems
If the suggested corrective action does not fix the problem, call your service representative.
Problem Action
Job did not print or incorrect
characters printed.
Make sure Ready appears on the operator panel before you send a job to
print. Press
Go to return to Ready.
Make sure print media is loaded. Press Go to return to Ready.
Verify the printer is using the correct printer language.
Verify you are using the correct printer driver.
Make sure the parallel, serial, ethernet, or USB cable is firmly plugged in at
the back of the printer. Make sure you are using the correct cable. Use IEEE
1284-compliant parallel cable. We recommend Lexmark part number
1329605 (10 ft) or 1427498 (20 ft). If you use RS-232 Serial, verify that a null
modem cable is used.
If the printer is connected through a switch box, try a direct connection.
Verify the correct paper size is selected through the operator panel, in the
printer driver, or in the software application.
Make sure PCL SmartSwitch and PS SmartSwitch are set to On.
Job did not print or incorrect
characters printed (continued).
If you are using a print spooler, verify the spooler is not stalled.
If you print across a network or on a Macintosh computer, see Solving
network printing problems.
Check the printer interface from the Setup Menu.
Determine which host interface you are using. Print a menu settings page to
verify the current interface settings are correct. See Printing the menu
settings page.
If you are using a serial interface:
• Make sure Honor DSR is set to Off.
• Check the protocol, baud, parity, and data bit settings. The settings on the
printer and on the host computer should match.
Printer seems to print slowly. Make sure you select the appropriate Paper Type setting before sending a job
to print.
If the Paper Type is set to Transparency, the printer adjusts the fuser
temperature and slows printing to improve the print quality. After printing on
this media, the printer requires additional time to warm the fuser after you
select another Paper Type setting (such as Plain Paper or Letterhead).
Reduce the complexity of your print job. Eliminating the number and size of
fonts, the number and complexity of images, and the number of pages in a job
may increase print speed.
Set Page Protect Off from the Setup Menu. See Page Protect for more
information.
