PAPER EMPTY SENSOR
Paper empty sensor (PE1) is mounted on the upper part of the multi paper feed tray and it
detects paper empty on the multi paper tray.
When there is paper on the tray, the actuator stands up and the sensor is turned OFF.
When paper on the tray went out, the actuator falls into the hole of the tray and the sensor is
turned ON.
2.1.2.1 Second Paper Feed Unit (Option)
MECHANISM
!
Since the second paper feed unit does not have driven motor, driving power for
feeding paper and carrying paper (driving force from M1) is transmitted to the
second paper feed unit from the printer via the connecting gear. Paper feed method
is the same as for multi paper feed tray.
!
As separation method, the separation pad method is used for the multi paper feed
tray, but the separator claw is used for the second paper feed unit.
!
The separator claw is the method that uses elasticity between the separator
installed at the paper fed cassette and the paper.
Only one sheet of paper is fed by one paper feed operation.
!
The paper feed solenoid (SL21) is controlled from the printer side via the relay
board (PWB-A) of the second paper feed unit.
