Code: 380-31
Description: Potential sensor calibration error (cut off) During drum potential sensor calibration, the drum potential sensor output voltage did not meet specification when test voltages (–100V, –800V) are applied to the drum.
Causes: • Potential sensor defective • Potential sensor harness disconnected • Potential sensor connector defective or disconnected • IOB defective • OPC connector defective • Development power pack defective

Code: 380-41
Description: Potential sensor calibration error (VD) During drum potential sensor calibration when adjusting the drum potential (VD), the drum potential sensor detects VD higher than VG (grid voltage). -or- When adjusting VD (drum surface potential of black areas after exposure), even after 5 adjustments of VG (charge corona grid potential), VD could not be set in the target range (–800±20+ VL + 130V)
Causes: • Potential sensor defective • Potential sensor harness disconnected • Potential sensor connector defective or disconnected • IOB defective • OPC connector defective • Development power pack defective • Charge corona unit worn out, dirty

Code: 380-51
Description: Potential sensor calibration (VL) During drum potential sensor calibration, when VL is adjusted, the pattern surface potential VL pattern is not within range 0V to -400V. (VL is the potential after exposing a white pattern.)
Causes: • Potential sensor defective • Potential sensor harness disconnected • Potential sensor connector defective or disconnected • IOB defective • OPC connector defective • Charge corona power pack defective • Development power pack defective

Code: 396-01
Description: Main motor error The main motor lock signal remains low for 2 seconds while the main motor is on.
Causes: • Drive mechanism overloaded • Motor driver board defective

Code: 410-00
Description: Quenching lamp error At the completion of auto process control initialization, the potential of the drum surface detected by the potential sensor is more than -400V, the prescribed value.
Causes: • Quenching lamp defective • Quenching lamp harness disconnected • Quenching lamp connector loose, defective

Code: 440-01
Description: Transfer output abnormal (voltage leak detected) When the transfer is output, the feedback voltage remains higher than 4V for 60 ms.
Causes: • Transfer power pack defective • Transfer current terminal, transfer power pack disconnected, damaged connector

Code: 440-02
Description: Transfer output abnormal release detection When the transfer is output, there is hardly any feedback voltage within 60 ms even with application of 24% PWM.
Causes: • Transfer power pack defective • Transfer unit harness disconnected • Transfer connector loose, defective

Code: 495-00
Description: Toner recycling unit error Encoder pulse does not change for 3 s after the main motor switches on.
Causes: • Waste toner transport has stopped due to motor overload • Toner end sensor detective, disconnected
