Troubleshooting 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 64 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 Supported print media on page 35. 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 sunlight, is interfering with communication. • No objects are placed between the two infrared ports. Internal print server • Make sure the internal print server (also called an internal network adapter or INA) is securely connected to the printer system board. • Make sure you are using the correct cable, that it is securely connected, and the network software is correctly set up. See the drivers CD that shipped with your printer for more details. High capacity feeder See Solving 2000-sheet drawer problems on page 98. (2000-sheet drawer) Printer memory Make sure printer memory is securely connected to the printer system board. USB/Parallel interface • Make sure the USB/parallel interface card is securely connected to the printer system board. • Make sure you are using the correct cable and that it is securely connected.
