Check for continuity across the coil. If none, replace the original
feed motor.
Reinsert the connector. Also check for continuity within the
connector cable. If none, remedy or replace the cable.
Check for continuity across the coil and connector terminals of
the original feed motor. If present, replace the DF driver PCB.
Check for continuity across the coil. If none, replace the original
conveying motor.
Reinsert the connector. Also check for continuity within the
connector cable. If none, remedy or replace the cable.
Check for continuity across the coil and connector terminals of
the original conveying motor. If present, replace the DF driver
PCB.
Reinsert the connector. Also check for continuity within the
connector cable. If none, remedy or replace the cable.
Check for continuity across the contacts of DF safety switch 1. If
none when the switch is on, replace DF safety switch 1.
With 5 V DC present at CN5-8 on the DF driver PCB, check if
CN5-3 on the DF driver PCB remains high when the actuator on
the machine front side of the original size detection PCB is turned
on and off. If it does, replace the original size detection PCB.
Remove any found.
With 5 V DC present at CN5-8 on the DF driver PCB, check if
CN5-3 on the DF driver PCB remains low when the actuator on
the machine front side of the original size detection PCB is turned
on and off. If it does, replace the original size detection PCB.
Remove any found.
With 5 V DC present at CN5-8 on the DF driver PCB, check if
CN5-1 on the DF driver PCB remains low when the DF timing
switch is turned on and off. If it does, replace the DF timing
switch.
