Paper Jams in Optional 500-Sheet Lower Cassette
Service Note Number:
the 500-sheet optional lower cassette is a leading cause of paper jams.
Either no-picks or multi-picks will occur, resulting in 13 and/or 41 errors.
Follow these instructions to adjust the cassette:
1 Fill the cassette completely full of paper of all the same weight (do
not overfill). Make sure the paper is flush against the rear paper
guide and that it rests under the front left corner tab.
2 Push down and release the front edge of the paper in the cassette
until it bounces. If the cassette is adjusted correctly, the purple-
colored indicator will stop in the very center of the indicator window.
If you need to adjust it, rotate the knob and try "bouncing" the paper
once again. Repeat these steps until the purple indicator stops in
the center of the window.
