Media Jams and the Paper Path

Media-based Problems

1. Check that the correct type of media is being used; Supported Paper
Weights, Page Sizes and Print Area on page 1-27 for the correct media
types and weights. The customer should be using a quality laser printer
paper. The printer may have trouble picking slick-finish paper.
2. Only Phaser 7700 series transparency film should be used in this printer.
3. Inspect the paper for bent, torn, or folded corners.
4. Ensure that the correct media type is set in the front panel.
5. Ensure that the paper guides are set correctly.
6. Ensure that the media is a supported type for the tray picked from. Tray 1
supports paper, transparencies, and thin cover/index paper. Trays 2-4
support paper only. The MPT supports all types.

Multiple-sheet Pick

1. Ensure that the paper is in good condition and appropriate for a laser
printer; quality office laser printer paper works best.
2. Ensure that the printer is printing within its environmental specifications by
using the built-in service diagnostics temperature test.
3. Ensure that the paper is correctly loaded in the tray and the tray has not
been over filled.
4. Try loading paper from a fresh ream. Flip the paper over.
5. Clean the pick rollers with a clean, dry, lint-free wipe.
6. Replace the paper pick rollers.
7. Check the tray's retard roller for damage.
8. Replace the paper tray.

Mis-pick

1. Check that the correct type of media is being used.
2. Try loading paper from a fresh ream. Flip the paper over.
3. Clean the pick rollers with a clean, dry, lint-free wipe.
4. Troubleshoot the pick roller assembly.

Skewed Image

The image area is twisted or is not parallel with the sides of the page but the
printer neither jams nor displays an error code.
1. Ensure that the paper guides are set correctly.
2. Check that the correct type of media is being used.
3. Ensure that the tray has not been over filled. (Skewed images are a
common defect when the MPT is filled too high.)
