CHAPTER 6 SELF DIAGNOSIS
6-41
E590
0001
The puncher does not return to home position when the puncher motor is
driven for 250 msec.
0002
The clock from the puncher motor clock sensor is disrupted for 60 msec or
more when the puncher motor is driven.
Main cause
The puncher home position sensor (PI1P) is faulty. The puncher motor
(M1P) is faulty. The puncher motor clock sensor (PI3P) is faulty. The
puncher driver PCB is faulty.
E592
In the course of sensor output automatic adjustment, the light-receiving
voltage is 2.5 V or less even when the light-emitting voltage is set to 4.4 V.
In the course of output automatic adjustment, the light-receiving voltage is
2.5 V or more even when the light-emitting voltage is set to 0 V.
In the course of sensor output automatic adjustment, the light-emitting volt-
age is set to 4.4 V or more.
0001 to 0005 Horizontal registration sensor
0006
