8.6.2 Lifter Limiter (right/left deck) Control Circuit
0015-4555
iR5065 / iR 5055 / iR5075 / / /
When the CPU on the DC controller PCB generates the motor drive signal, the lifter motor in response starts to rotate to move the lifter. When the deck reaches the
lifter sensor, the deck lifter detection signal arrives at the CPU, causing the CPU to stop the deck lifter drive motor.
The machine is equipped with a deck limit sensor to make sure that the lifter will not go awry. When the surface of paper reaches the deck limit sensor, the limit
signal arrives at the DC controller PCB to cut off the drive signal, thereby stopping the limit motor.
The following block diagram shows the control circuit:
