High Voltage Power Source: Paper Transfer : 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.
  • BCU error (signal error)
  • HVPS defective

Load error

  • Transfer roller's impedance increases.
  • Transfer unit is not set properly.
  • Cycle the main power off/on.
  • Reconnect or replace the harness of the HVPS (power pack).
  • Reconnect or replace the harness between the BCU and the HVPS.
  • Reset or replace the transfer unit.
  • Check if the contact and separation movement of the transfer unit works correctly.
  • Replace the HVPS.
  • Replace the BCU.

When the machine does not detect the high/low signal for a specified time after the transfer roller contact motor has been turned on.

  • Motor overload, Motor defective
  • Connector disconnected
  • Harness broken
  • Interlock mechanism is defective.
  • Cycle the main power off/on
  • Check if the contact and separation movement of the transfer unit works correctly.
  • Replace the transfer roller contact motor.
