Job did not print or incorrect

characters printed (continued).

If you are using a print spooler, verify the spooler is not stalled.

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

.

Unexpected page breaks

appear.

Increase the Print Timeout value in the

Setup Menu

.

Transparencies jam.

If you just turned the printer on or the printer has been idle for a period of

time, print on paper before trying to print on transparencies.

Disabling Power Saver may also prevent transparencies from jamming

after the printer has been idle.

Paper is jammed in the fuser.

Rotate the fuser pressure release lever down and remove the jammed

paper. See

Clearing paper jams

for more information.

Part of the printed page was

clipped or is cut off.

Make sure you have the correct size paper in the paper tray and the paper

size is set correctly for the paper in the tray.

Printer is connected to the

USB port, but will not print.

Make sure you are using Windows 98, Windows 2000, Windows Me, or

another USB-capable operating system supported by your manufacturer.

Paper does not feed properly.

Make sure you are using recommended media. Do not use 16 lb paper or

paper greater than 32 lb 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.
