9-14 Paper Feeding Problems
Is the proper paper loaded?
Load proper paper in the cassette or multi-purpose feeder. (See Chapter 2,
"Paper Handling.")
Select <TRANSPARENCY> in <PAPER TYPE> in <COMMON SETTINGS> of
the Menu. (See "Specifying the Paper Type," on p. 5-4.)
Is the proper paper loaded?
Check that the size, thickness and type of the paper you are using. (See "Print
Media Requirements," on p. 2-1.)
Is the proper paper loaded correctly?
Be sure to fan the paper stack before loading it in the cassette. This keeps the
sheets of paper from sticking together.
Is the output tray free of obstructions?
Do not place the delivered paper back on the output tray. (See "Face Down
Paper Output Area," on p. 2-17.)
Do not place objects other than paper on the output tray. (See "Face Down
Paper Output Area," on p. 2-17.)
Is the machine installed in a proper location?
Check that the machine is installed in the proper location. (For information
about specifications of the machine, see "Specifications," on p. 11-1. For safety
warnings and cautions, see "Installation," on p. xiv.)
Are the envelopes loaded correctly?
Make sure the envelopes are loaded correctly. (See "Loading Envelopes in the
Cassette," on p. 2-7, or "Loading an Envelope in the Multi-Purpose Feeder," on
p. 2-13.) Do not load more than 20 envelopes in the cassette. Load an envelope
one by one in the multi-purpose feeder.
Is the proper envelope loaded?
Load the recommended envelopes (COM10, MONARCH, DL, or ISO-C5) in the
cassette or multi-purpose feeder. (See "Loading Envelopes in the Cassette," on
p. 2-7, or "Loading an Envelope in the Multi-Purpose Feeder," on p. 2-13.)
