6. Replace the toner supply unit.
7. Replace the ITB unit.
SC381-01
Error Name
Potential Sensor Output High Error (K)
Pattern
D
Error Condition
The voltage detected by the potential sensor during the reading of a non-image area on the drum is too
high.
Major Cause
 Potential sensor (SEN5) is dirty (foreign objects, such as toner, entering the probe window).
 Potential sensor is defective.
Solution
1. Check if the potential sensor (SEN5) is dirty.
Use a blower brush to clean the potential sensor (SEN5).
Turn the main power of the machine OFF and then ON, and then perform process control.
2. Replace the potential sensor (SEN5).
SC382-01
Error Name

Pattern
D
Error Condition
The voltage detected by the potential sensor during reading of a non-image area on the drum is too low.
Major Cause
 Potential sensor (SEN5) is not connected properly.
 Potential sensor is defective.
 Potential sensor (SEN5) harness is damaged.
