A. Broken main charger wire.
B. Leaking main charger housing.
C. The connector terminals of the
high-voltage transformer PCB
make poor contact.
D. Defective main PCB.
E. Defective engine PCB.
F. Defective high-voltage

2. Exposure lamp fails to light.
A. The connector terminals of the
exposure lamp make poor
contact.
B. Defective inverter PCB.
C. Defective scanner control PCB.
Replace the wire.
Clean the main charger wire and shield grid.
Reinsert the connector. Also check for
continuity within the connector cable. If none,
repair or replace the cable.
Check if CN2-B58 on the main PCB goes low
when maintenance item U100 is run. If not,
replace the main PCB.
Check if CN9-14 on the engine PCB goes low
when CN2-B58 on the main PCB goes low
while maintenance item U100 is run. If not,
replace the engine PCB.
Check if main charging takes place when
CN1-1 on the high-voltage transformer PCB
goes low while maintenance item U100 is
run. If not, replace the high-voltage
transformer PCB.
Reinsert the connector. Also check for
continuity within the connector cable. If none,
repair or replace the cable.
Check if the exposure lamp lights when
CN1-5 and 1-6 on the inverter PCB go low
while maintenance item U061 is run. If not,
replace the inverter PCB.
Check if CN2-12 on the scanner control PCB
goes low when maintenance item U061 is
run. If not, replace the scanner control PCB.
