Description
Process control self-check
successfully completed.
Vt maximum or minimum
error is detected.
Not enough data can be
sampled.
When the K5 is more than
the value of
SP3-362-003 or less
than the value of
SP3-362-004, the error
54 is displayed.
Possible Causes/Action
-
• Defective development unit
Vt maximum error and an image is faint:
1. Replace the toner hopper unit.
Vt maximum error and an image is O.K:
1. Replace the development unit.
2. Replace the BCU board.
Vt minimum error:
1. Replace the development unit.
2. Replace the BCU board.
• Solid image is not sufficient density:
1. Retry the process control.
2. Replace the ID sensors.
3. Replace the BCU board.
• Solid image is O.K.
1. Replace the ID sensors.
2. Replace the BCU board.
• ID sensor is dirty:
1. Clean the ID sensors.
