Tips for avoiding paper jams
By selecting the correct media types, most paper jams can be avoided.
When a paper jam occurs, follow the steps outlined on page 9.1.
• Follow the procedures on page 5.5. Ensure that the adjustable guides
are positioned correctly.
• Do not overload the tray. Ensure that the paper level is below the
paper capacity mark on the inside wall of the tray.
• Do not remove paper from the tray while your printer is printing.
• Flex, fan, and straighten paper before loading.
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in a tray.
• Use only recommended print media. See page 5.1.
• Ensure that the recommended print side of print media is facing down
in the tray, or facing up in the multi-purpose tray.
Troubleshooting checklist
If the printer is not working properly, consult the following checklist. If the
printer does not pass a step, follow the corresponding suggested
solutions.
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 9.6.
Print a demo page
to verify that the
printer is feeding
paper correctly. See
page 2.8. • 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 9.6.
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
interrupted during printing, see page 9.9.
