Exit Module Malfunction

Exit Module Elevator Inoperative
1. Is there Scanner Power Supply working properly? Lift the DADF and observe the scanner
lamps. If the lamps are on and the scanhead moves, the Scanner Power Supply is supply-

Media Path and Transport Problems

For paper path and media-based problems, first check for displayed error codes. If a code is
displayed, see Error Message Troubleshooting for the appropriate troubleshooting procedure. If
no code is displayed, use the following procedures to isolate the problem.
Initial Actions
• Check that the correct type of media is being used, for information on the correct media
type and sizes refer to the Paper Tips page.
• Ensure the system is operating under the right environmental conditions.
• Ensure the correct weight of paper is being used.
• Ensure that envelopes are of an acceptable size and oriented with the flap up for Tray 1
and the flap down for Trays 2, 3, and 4
• Ensure that the correct media is in the correct media tray. The paper guides indicate to the
system the size of media being used. Ensure the media guides are set correctly.
• Inspect the paper for bent, torn or folded corners.
• Check to ensure no small pieces of paper are in the paper path.
• Run the Service Diagnostics Paper Path Status test to test all path sensors.
• Try printing from a fresh, unopened ream of paper.
