18.3.3 Bypass paper lifting motion control
• It turns the bypass paper pick-up solenoid ON when the bypass 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 bypass paper pick-up solenoid will be ON again. The
paper lifting cam will then rotate to move the paper lifting plate down to the waiting posi-
tion.
• 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.
• When the paper jam occurs, the paper lifting plate will move down to the waiting position.
• 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 lift-up position sensor.
