ing, transfer charging, developing)
output is faulty.
• Composite power supply PCB
(faulty)
• DC controller PCB (faulty)
• Wiring (faulty; short circuit, open
circuit)
A BD error has occurred.
• Laser unit (faulty)

• Laser driver PCB (faulty)
• Image processor PCB (faulty)
The laser scanner motor fails to
lock.
• Laser scanner motor (M3;
faulty)
• Laser scanner driver PCB
(faulty)
• DC controller PCB (faulty)

3. OPERATIONS AND TIMING
Description
• The difference between the high-voltage
control signal and the actual high-voltage
output is more than a specific value.
• Any of the primary charging roller, transfer
charging roller, and developing bias has
an output error.
• The BD signal is not generated within 2
sec after the laser has been turned on.
• The BD signal cycle has a discrepancy.
• A specific speed is not reached after the
laser scanner motor drive signal has been
generated.
• The speed deviates after it has reached a
specific speed.
• The communication data is not updated
for 8 sec or more.
• The check sum of the communication data
is different for three times in a row.
• The scanner does not return to home
position after it has started to move.
• Activation of the lamp has been detected
during standby.
• Deactivation of the lamp has been detect-
ed during copying.
• An error has been detected in the commu-
nication between the DC controller PCB
an the image processing PCB.
