Other printing problems

Problem
Your job did not print or incorrect
characters printed.
You cannot print color.
You cannot print the menu
settings page.
You cannot print using the
LocalTalk port.
Paper does not feed properly.
The printer seems slow to print.
Action
Make sure Ready (or Power Saver) appears on the first line of the operator
panel display before you send a job to print. Press Go to return the printer to
the ready state.
If Ready Hex appears on the operator panel display, you must exit Hex Trace
mode before you can print your job. To exit Hex Trace mode, reset the printer
or turn the printer off and back on.
Make sure the printer is not displaying a Toner Empty message. If it is, you
cannot print until you replace the specified toner cartridge.
If you're using a parallel interface, make sure you're using an IEEE
1284-compliant parallel cable. We recommend Lexmark part number
1329605 (10 ft) or 1427498 (20 ft) for the standard parallel port.
If you're using a Lexmark internal or external network adapter, verify it is set
up properly and the network cable is securely connected. Refer to the
documentation that came with your adapter, or the network documentation
on the drivers CD for more information.
Make sure the Color Correction menu item is not set to Black and White.
Make sure you're using a color printer driver.
Make sure color printing is selected from the printer driver.
Make sure the selected paper source holds A4, letter, or legal size paper.
Make sure the Paper Type setting for the selected source is Plain Paper.
Make sure neither LocalTalk Port nor LocalTalk Buffer is set to Disabled in
the LocalTalk Menu.
Verify the printer is set up correctly in the Macintosh Chooser.
Make sure you're using recommended media. If you are using 16 lb paper,
make sure it has been placed in tray 1 only. Do not use 16 lb paper with the
duplex unit.
Make sure the adjustable guides in the paper tray are adjusted properly for
the media you loaded.
Make sure the stack of media does not exceed the maximum stack height
indicated on the tray.
If Photo Enhance is On, it may take longer to print some complex jobs or jobs
formatted for larger paper. You can set Photo Enhance to Off and select the
600 dpi setting if you need the job to print faster. See
more information.
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
information.
