PAPER FEED

2.2 PAPER FEED

Power On

When paper is placed on the tray, the paper set sensor [A] in the tray actuates and
switches on the bottom plate lift motor [B]. The top of the stack raises the pick-up
roller unit until the actuator on this unit actuates the pick-up roller position sensor
[C] and switches the motor off.

Paper Separation and Feed

The pick-up roller [D] picks up the original, and the feed belt [E] feeds the sheet to
the grip roller. The separation roller [F] reverses if more than one sheet is fed

Bottom Tray Lift

As sheets feed from the top of the stack:
• The pick-up roller unit descends until the actuator on the pick-up roller unit drops
out of the pick-up roller position sensor [C].
• The bottom plate lift motor switches on to raise the stack until the actuator enters
the pick-up roller unit position sensor again and switches the motor off.
• This repeats until the end of the job or until paper runs out.

Paper Near-end

Near-end is detected when the actuator [G] on the bottom plate enters the near-
end sensor [H].

Paper End

After the last sheet feeds the paper set sensor [A] goes off and signals paper out.
