Description: Development bias abnormal Type: 2 - Description - The main control board notifies the SCU that the development bias output from the high-voltage power pack does not reach the target due to such causes as a leak or power pack failure. - Detection Timing - During output of the development bias
Causes: • High voltage power supply • Leak locations SP-Log: 7-402-3
Code: SC361
Description: Revolver HP sensor abnormal - Stays off Type: 2 - Description - The main control board notifies the SCU when the revolver home position sensor does not go on even though the revolver was sent to the home position during the revolver homing process. - Detection Timing - During the development revolver homing process
Causes: • Revolver unit • Revolver HP sensor SP-Log: 7-402-3
Code: SC362
Description: Revolver HP sensor abnormal - Stays on Type: 2 - Description - The main control board notifies the SCU when the revolver home sensor does not go off even though the revolver was moved from the home position to an appropriate color. - Detection Timing - During copying
Causes: • Revolver unit • Revolver HP sensor SP-Log: 7-402-3
Code: SC363
Description: Revolver setting error Type: 2 - Description - The cartridge detector detects that there is no cartridge when the revolver stops rotating. - Detection Timing - When the revolver stops rotating at the black development position
Description: Drum potential sensor calibration error Type: 5 - Description - During calibration, the drum is floated (disconnected from ground) and biases of dc -200 V and dc -800 V are applied. The main control board notifies the SCU when the potential sensor output value for either bias is not within a predetermined tolerance. - Detection Timing - During the forced process control self check or the initial process control self check
Causes: • Drum potential sensor • Main control board SP-Log: 7-402-3
Code: SC382
Description: VD adjustment error (charging failure - the target is not reached within 40 trials) Type: 5 - Description - The main control board notifies the SCU when VD does not come within ±5 V of the target after 40 trials in the VD check mode during the potential control process. - Detection Timing - During the process control self check
Causes: • High voltage power supply • Main control board SP-Log: 7-402-3
