DRUM HOME POSITION DETECTION

2.4 DRUM HOME POSITION DETECTION
[A]
LEDs are added to inform the operator when the drum is at the exact home
position and can be pulled out. The drum home position is monitored by the drum
home position sensor [A], which is newly added for the actuator disk [B] on the
pressure cylinder.
Green LED [C] turns on when the drum is at the home position.
Red LED [D] warns that the drum is not at the home position.
NOTE: If the red LED lights when the machine is in standby mode, the drum is not
at the home position and the front door must be closed to reset the drum
position.
