High Voltage Power Source: Charge: Output Error

The machine detects the error detection signal “L (unexpected)” 10 times for 200 msec consecutively when monitoring the error signal every 20 msec during outputting the PWM signal.

Hardware error

  • Input / Output connector is disconnected.
  • Input / Output harness is short-circuited.
  • Surface/air clearance insufficient (arc discharge)
  • BCU error (signal error)
  • HVPS defective

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)
  • Unexpected deterioration of drum and over current due to pinholes gap error between the drum and charge roller (PCU error).
  • Over current due to drum surface condensation
  • PCU is disconnected.
  • Cycle the main power off/on.
  • Replace the HVPS.
  • Replace the harness of the HVPS.
  • Replace the harness of the PCU.

ID Sensor Calibration Error

Regular reflection optical output voltage of the ID sensor: Vsg_reg cannot be adjusted to within target range.

Upper limit (SP3-320-013: initial value 4.5V)

Lower limit (SP3-320-014: initial value 3.5V)

  • ID sensor connector missing/connection fault
  • ID sensor detection window dirt
  • ID sensor malfunction
  • Check the ID sensor connector. If it is not connected, reconnect it.
  • Check for dirt on the ID sensor detection window. If the detection window is dirty, clean by the predetermined method (do not wipe it dry).
