There are two paper trays and a by-pass feed table [A].
The first [B] and second [C] paper trays each hold 250 sheets. The by-pass
feed table can hold 1, 10, or 100 sheets of paper, depending on the paper
size.
The semicircular feed rollers [D] drive the top sheet of paper from the tray to
the registration rollers [E] through the relay rollers [F].
The tray has two corner separators (see [F] in the diagram in the "Paper Lift
Mechanism" section), which allow only one sheet to feed at a time. The
corner separators, along with the tray's springs, also serve to set the height
of the paper stack.
When the tray is closed after the paper is loaded, the paper size actuator
located at the front right of the tray pushes against the paper size sensor.
This informs the cpu what paper size is loaded in the tray and that the tray is
in place.
There is a relay sensor [G] located between the relay rollers. This sensor is
used for paper jam detection.
