The bypass tray can hold 500 sheets of standard weight paper.
The bypass tray uses the standard FRR (Feed and Reverse Roller) feed system
with a pick-up roller, feed roller, and separation (reverse) roller. ! Handling
Paper> Paper Feed Methods> Forward and Reverse Roller (FRR)
When the job starts, the feed clutch [A] switches on and rotates the pick-up roller
[B]. At the same time, the pick-up solenoid [C] switches on and lowers the pick-up
roller. The lift motor switches on to raise the stack until the top of the stack reaches
the correct feed level and the paper pushes the pick-up roller and actuator [D]
down, deactivating the lift sensor [E], which stops the lift motor.
The rotating pick-up roller picks up and feeds the first sheet to the feed roller [F]
and separation roller [G]. When the feed sensor [H] detects the leading edge of the
sheet, the pick-up solenoid raises the pick-up roller and the feed roller feeds the
sheet.
NOTE: Unlike the separation rollers in the LCT, the separation roller [G] always
remains in contact with the feed roller above.
When the pick-up roller [B] lowers far enough to deactivate the lift sensor [E], the
lift motor switches on to raise the bottom plate until the actuator moves out of the
slot of the lift sensor again and switches off the lift motor. This movement is
repeated to maintain the correct height of the stack for paper feed.
