PAPER LIFTING MOTION CONTROL
†
It turns the MP tray Pick-Up Solenoid (SL2) ON when the MP tray paper
feed is started. The Lifting Cam will rotate to move the Paper Lifting plate
up to the feeding position.
†
When the printing is finished, the MP tray Pick-Up Solenoid (SL2) will be
ON again. The Paper Lifting Cam will then rotate to move the Paper
Lifting plate down to the waiting position.
†
The Paper Lifting plate will stay at the feeding position while the job is
being executed. It will move down to the waiting position when the job is
finished and no following printing is demanded.
†
If a paper misfeed occurs, the Paper Lifting Plate is lowered to its standby
position during pre-drive performed after the misfed sheet of paper has
been cleared and the door has been closed.
†
The position of the Paper Lifting Plate is detected by the detection plate
which is mounted coaxially with the Paper Lifting Plate, and also by the
MP tray Lift-Up Sensor (PC14).
