2-4 Phaser 3140/3155/3160 Printer Service Manual
Theory of Operation
Paper Tray
In the Paper Tray, paper is separated by the Holder Pad mounted to the center of
the tray. Both the side guide and the rear guide can be adjusted for various paper
sizes. The Paper Empty Sensor detects when the Paper Tray needs to be loaded
with paper.
Tray Holder Pad
Individual sheets are separated by the Tray Holder Pad in the Paper Tray. When
paper feeds into the printer, it passes over the Tray Holder Pad Assembly which
uses a spring loaded friction pad to separate the sheets of paper.
Manual Feeder
The manual feeder is used to hold non-standard or custom paper sizes and special
media (envelopes, transparencies, etc.). The manual feeder can hold 1 sheet of
paper or 1 envelope.
