Action
• Make sure the toner cartridge assembly is
installed properly.

damaged and is firmly plugged into the
connector on the back of the printer.

– If you cannot print a menu settings page,
contact the next level of support.
– If you can print a menu settings page, the
problem is one of the following:
• Computer
• Software program
• Cable
• (USB only) failed ASIC or controller card.
Replace card.
Note: Test by unplugging USB and
replugging it with the printer on. If the
computer indicates "unknown device,"
replace the card.
If you are using a 3,000 or 6,000 page toner
cartridge and the Toner Low alarm is set to on,
the printer stops printing until you replace the
toner cartridge.
Download the correct Lexmark setup utility from
the Lexmark Web site at www.lexmark.com to
change the Toner Low alarm.
Make sure the printer cover is closed.
• Make sure the toner cartridge is installed
correctly.
• Install a new toner cartridge.
• Don't overfill Tray 1 or the optional Tray 2 (see
media capacities in the media types and sizes
table in the User's Reference).

the edges of the media.
