14.7.22 Checking the Photointerrupters
0008-8573
/ iR8070
The machine's photointerrupters may be checked by a conventional
meter or its service mode:
a. Using a Meter
1) Set the meter range to 30 VDC.
2) Connect the - probe of the meter to GND of the DC controller PCB.
3) Connect the + probe of the meter to the terminals (DC controller
PCB) indicated in the following table.
4) Make checks as instructed.
b. Using Service Mode
1) Start service mode (COPIER>I/O), and check the appropriate
address.
Turning on/off a sensor can start the machine's motor or the like. Take
full care.
