Definition
Symptom Possible Cause
401 B
Transfer roller leak error (positive electrode)
• The feedback voltage of the
transfer roller has been more than
the certain voltage for 200msec.
(Open detecting condition)
•
The feedback voltage of the
transfer roller has been insufficient
for 200msec. (Leak detecting
condition)
This error doesn’t happen when the front
door (the inter lock) opens.
• Defective harness connected to HVP
• Defective the MD
402 B
Transfer roller leak error (negative electrode)
The feedback voltage of the transfer
roller has been more than the certain
voltage (more than 4.5V) for 200msec.
This error doesn’t happen when the front
door (the inter lock) opens.
• Defective the MD
•
Defective harness connected to the
HVP
411 B
Separation high-voltage error
The maximum rate of PWM duty (50%)
occurs ten times in series (20msec x 10)
This error doesn’t happen when the front
door (the inter lock) opens.
• Defective the MD, HVP Connection
harness.
440 B
Transfer electric plus current error
Detecting "0" (Abnormal) ten times in
series (200ms) while monitoring "HVP: T
+: Output error detection signal" every
20m seconds.
