Check for continuity across the coil. If none,
replace the ozone exhaust fan motor.
Check for continuity across the connector
terminals. If none, replace them.
Run simulation 10 and check if CN11-13 on
the main PCB goes low (about 12 V at half
speed). If not, replace the main PCB.
Check for continuity across the coil. If none,
replace the paper feed solenoid.
Check for continuity across the connector
terminals. If none, replace them.
Run simulation 12 and check if CN2-4 on the
main PCB goes low. If not, replace the main
PCB.
Check for continuity across the coil. If none,
replace the bypass solenoid.
Check for continuity across the connector
terminals. If none, replace them.
Run simulation 12 and check if CN2-2 on the
main PCB goes low. If not, replace the main
PCB.
Check for continuity across the coil. If none,
replace the registration solenoid.
Check for continuity across the connector
terminals. If none, replace them.
Run simulation 12 and check if CN14-2 on
the main PCB goes low. If not, replace the
main PCB.
