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.

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.
