Service Manual

 

When paper is placed on the tray, the 1st paper set sensor in the
tray actuates and switches on the 1st tray lift motor. The pick-up
roller unit drops and the top of the stack in the tray pushes up the
pick-up roller unit until its actuator actuates the 1st bottom plate
position sensor [A] and switches the motor 1st tray lift motor off.
The 1st pick-up roller HP sensor [B] controls the operation of the
1st pick-up motor [C]. The 1st pick-up motor is off when the actua-
tor is up and there is no paper in the tray. This is the pick-up roller
home position. When the actuator de-actuates the sensor after the
tray lifts, this switches on the 1st pick-up roller motor. At the end of
the job, the actuator descends with the bottom plate and switches
the motor off.
The pick-up roller [D] picks up the sheet, and the feed belt [E] feeds
the sheet to the paper feed roller [F]. The separation roller [G]
reverses if more than one sheet is fed.
This is a standard FFR device
The paper feed sensor [H] detects the timing of the feed and sig-
nals a jam if the paper does not arrive or if the paper stops.
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 1st bottom plate position sensor [A].
This activates the 1st tray lift motor.
