<Paper Stack Lifting>
D When the Paper Descent Key (UN5/6) is pressed*
into the copier, it energizes the Lift-Up Motor (M13/14) and the motor starts turning
forward.
D The rotation of the motor is transmitted via a gear train to the worm gear and the
Paper Lifting Arm mounted on the same shaft, raising the Paper Lifting Plate. This
raises the paper stack.
D When the top of the paper stack is pressed against the Paper Take-Up Roll and the
paper stack is further raised, the light blocking plate of the Paper Take-Up Roll Assy
blocks the Lift-Up Sensor (PC65/66). This deenergizes the Lift-Up Motor and the
paper stack raising motion is completed.
D As the paper is consumed and the top level of the paper stack lowers, the Lift-Up
Sensor is unblocked. Then, the Lift-Up Motor is energized again to raise the paper
stack until the Lift-Up Sensor is blocked again. This means that a constant pressure
is maintained between the paper and the Paper Take-Up Roll regardless of the
amount of paper still available for use.
*1: The Lift-Up Motor is energized at the following timings, in addition to the press of the
Paper Descent Key (UN5/6).
D Turning ON the Power Switch
D Opening and closing the door
D Operating the panel
D Detecting a sheet of paper on the Multi Bypass Table
