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
Printing the menu settings page on page 60
for more information.
• Make sure the option is selected in the software application you are using.
For Macintosh computer users: Make sure the printer is set up in Chooser.
The following table lists printer options and suggested corrective actions for related problems. If the
suggested corrective action does not fix the problem, call your service representative.
Option Action
Drawers • Make sure the connection between drawers and the printer is secure.
• Make sure the print media is loaded correctly.
Duplex unit Make sure the connection between the duplex unit and the printer is secure. If the
duplex unit is listed on the menu settings page, but print media jams when it
enters or exits the duplex unit, the printer and duplex unit may not be properly
aligned.
Finisher • Make sure the connection between the finisher and the printer is secure. If the
finisher is listed on the menu settings page, but print media jams when it exits
the printer and enters the finisher, it may not be properly installed. Reinstall the
finisher.
• Make sure you are using a print media size compatible with your optional
output bins. See Media sizes and support .
Flash memory Make sure flash memory is securely connected to the printer system board.
Hard disk with
adapter Make sure the hard disk is securely connected to the printer system board.
Infrared adapter If infrared communication stops or does not occur, make sure:
• The distance between the two infrared ports is 1 meter
(39 in.) or less. If communication does not occur between ports, move the ports
closer together.
• Both ports are stable.
• The computer and the printer are on a level surface.
• The angle of communication between the two infrared ports is within 15
degrees of either side of an imaginary line drawn between the two infrared
ports.
• No bright light, such as direct sun light, is interfering with communication.
• No objects are placed between the two infrared ports.
