(1) No image
(entirely white).
Causes
1. No original present.
2. No main charging.
3. No transfer charging.
4. All blank lamps on.
5. Developing section not driven.
1. No original present.
2. No main charging.
A. Broken main charger
wire.
B. Leaking main charger
housing.
C. The connector ter-
minals of the high-
voltage transformer
PCB make poor
contact.
D. Defective main PCB.
E. Defective high-voltage
transformer PCB.
3. No transfer charging.
A. Broken transfer
charger wire.
B. Leaking transfer
charger housing.
C. The connector termi-
nals of the high-
voltage transformer
PCB make poor
contact.
D. Defective main PCB.
E. Defective high-voltage
transformer PCB.
Place an original in the correct position.
Replace the wire.
Clean the main charger housing.
Check for continuity across the terminals. If none, replace
them.
Run simulation 32 and check if CN1-21 on the main PCB
goes low; or check if the correct control voltage is applied
to CN1-25. If not, replace the main PCB.
If main charging does not take place during simulation 32
after the main PCB has been found to be normal, replace
the high-voltage transformer PCB.
Replace the wire.
Clean the transfer charger housing.
Check for continuity across the terminals. If none, replace
them.
Run simulation 31 and check if CN1-22 on the main PCB
goes low; or check if the correct control voltage is applied
to CN1-26. If not, replace the main PCB.
If transfer charging does not take place during simulation
31 after the main PCB has been found to be normal,
replace the high-voltage transformer PCB.
Causes
Check procedures/corrective measures
