6.1 OVERVIEW

There are two paper trays and a by-pass feed table [A].
The upper [B] and lower [C] paper trays each hold 250 sheets. The by-pass
feed table can hold 1, 10, or 80 sheets of paper, depending on the paper type.
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 the paper size sensor. This
informs the cpu what paper size is loaded in the tray and that the tray is in
place.
The by-pass feed table uses a feed roller and friction pad system to feed the
top sheet of paper to the registration rollers.
In humid environments, copy paper may crease as it comes out of the fusing
unit. The optional tray heaters [G] are available as service parts to keep copy
paper dry. It can be installed for both paper trays.
