By-Pass Tray
6.12.3 BY-PASS PAPER SEPARATION
When the by-pass paper end sensor [A] sensor detects paper and the machine gets a
by-pass printing job, the by-pass solenoid [B] drops the by-pass pick-up roller [C] onto the
top of the paper stack on the by-pass tray. After that, the by-pass pick-up roller moves one
sheet of paper to the feed roller.
This machine uses an FRR (Feed and Reverse Roller) system for feeding paper.
There is friction between the by-pass feed roller [E] and separation roller [D]. This friction
separates the top sheet of paper from the stack.
6.12.4 BY-PASS PAPER SIZE DETECTION
There are two paper side plates [A] on the by-pass tray. These connect with the paper size
sensor [B] through a rack-and-pinion mechanism.
