7-22 Troubleshooting
Solution
The cut sheet feeder may be incorrectly
installed on the printer. Remove and
reinstall the cut sheet feeder making
sure that the mounting notches are
properly mated with the pins on the
printer. Refer to 5-3.
The cut sheet feeder may be out of
paper. Load more paper in the cut sheet
feeder's bin.
The paper set levers of the cut sheet
feeder may not be pushed back. After
loading a stack of paper in the cut sheet
feeder, make sure to push the paper set
levers back. Refer to 5-6.
The two small levers on the paper
guides may not be set correctly. When
printing envelopes, push down on the
two small levers until they lock into
position.
The left and right paper guides may be
placed too close together and are
preventing the paper from feeding
smoothly. Adjust the position of the
paper guides so that the paper can move
up and down freely. Refer to 5-6.
