consecutively during high voltage (charge/development) output.

H/W error

• Output contact setting fault

• Controller connector set fault

• Ground fault of output high voltage path

• Surface/air clearance insufficient (arc discharge)

• Controller harness disconnection, short-circuit

• PCU setting fault

• Control board _IOB error (related signal error)

• HVP_CB error

Load error

• Grounding fault of charging output, short-circuit with other outputs

• Surface/air clearance insufficient in charging output path (including

distance from other outputs)

• Abnormal deterioration of drum, and over current due to pinholes

• Drum vs charge roller gap error (PCU error).

• Over current due to drum surface condensation

• Grounding fault of developing output, short-circuit with other outputs

• Surface/air clearance insufficient in developing output path

(including distance from other outputs)

• Other

• Turn the main power OFF/ON.

• Reset or replace the harness of high voltage power supply feed path

• Reset or replace the harness between IOB-HVP_CB

• Reset or replace the PCU
