You are using an incompatible parallel
cable
If you are using a parallel interface, make sure you
are using an IEEE 1284-compliant parallel cable. We
recommend Lexmark part number 1329605 (10 ft) or
1427498 (20 ft) for the standard parallel port.
The printer is in Hex Trace mode.
If Ready Hex appears on the display, you must exit
Hex Trace mode before you can print your job. Turn
the printer off and back on to exit Hex Trace mode.

The job is too complex
Reduce the complexity of the print job by eliminating
the number and size of fonts, the number and
complexity of images, and the number of pages in

Solving option problems

If an option does not operate correctly after it is
installed or if it quits working:
• Turn the printer off, wait for about 10 seconds,
and turn the printer on. If this does not fix the
problem, unplug the printer, and check the
connection between the option and printer.
•
Print the menu settings page and check to see
if the option is listed in the Installed Options list.
If the option is not listed, reinstall it. See the
User's Guide for more information.

application you are using.
If the suggested corrective action does not fix the
problem, call your service representative.
