Exit jams
An exit jam occurs when the media has not been detecting exiting the printer
when it should have.
1.
Ensure the media being used is in good shape, with not torn or ragged
edges that could jam in the paper path.
2. Inspect the paper path for obstructions.
3. Check the alignment of the fuser to the lower roller guide. Refer to the
Chapter 9 topic “Lower roller guide alignment” on page 9-9.
4. Ensure the exit motor and exit rollers operate correctly. Clean the exit
rollers. Ensure the teeth on the exit motor gear are correctly meshing
and are not broken.
5.
Check that the exit sensor is working correctly.
Printing and print quality problems
Paper edges are rippled or wrinkled
1. If possible, you should feed the paper into the printer with the paper's
grain parallel to the paper path (the direction the paper travels while it
is fed through the printer). Most papers are labeled either
short-grained or long-grained. In short-grained paper the grain is
parallel to the short axis of the paper and the paper should be loaded
in the landscape orientation. Conversely, in long-grained paper the
grain is parallel to the long axis of the paper.
Large spots or blobs on the print
1.
If the spots are circular, there is probably a blob of ink on the bail
rollers or the bottom rollers. Clean the rollers.
2. Ink on the drum will often soil the back of a print.
3. If the spots have long trailing smears look for contamination on the
back tension blade. Clean the blade.
