Troubleshooting checklist
If the printer is not working properly, consult the following checklist. If the
printer does not pass a step, follow the corresponding troubleshooting
suggestions.
Condition Suggested solutions
Make sure that the
Status LED on the
control panel lights
green and Ready is
shown on the
display.
• If the Status LED is off, check the power
cord connection. Check the power switch.
Check the power source by plugging the
power cord into another outlet.
• If the Status LED lights red, check the
display message. See page 9.7.
Print a demo page
to verify that the
printer is feeding
paper correctly. See
page 2.6.
• If a demo page does not print, check the
paper supply in the tray.
• If the paper jams in the printer, see
page 9.1.
• If an error message appears on the
display, see page 9.7.
Check the demo
page to see if it
printed correctly.
If there is a print quality problem, see
page 9.11.
Print a short
document from a
software application
to verify that the
computer and
printer are
connected and are
communicating
correctly.
• If the page does not print, check the cable
connection between the printer and the
computer.
• Check the print queue or print spooler to
see if the printer has been paused.
• Check the software application to ensure
that you are using the proper printer driver
and communication port. If the page is
