  • Code: 184
  • Description: CIS transmission error
    When the CIS is powered on, the ADF detects one of the following abnormal conditions on the CIS unit:
    • The SOUT signal does not go high within 1 s after power on.
    • The SOUT signal goes high within 1 s after power on, but the SBU ID cannot be read after 3 attempts.
  • Causes: • CIS unit defective
    • Harness between the CIS, ADF is disconnected
  • Code: 202
  • Description: Polygon mirror motor error 1: Timeout at ON
    The polygon mirror motor unit did not enter "Ready" status within 20 sec. after the motor was turned on, or within 20 sec. after the speed of rotation was changed.
  • Causes: • The polygon mirror motor PCB connector is loose, broken, or defective
    • Polygon mirror motor PCB defective
    • Polygon mirror motor defective
    • IPU defective
  • Code: 203
  • Description: Polygon mirror motor error 2: Timeout at OFF
    The polygon mirror motor did not leave "Ready" within 3 sec. after the motor was switched off. (The XSCRDY signal did not go HIGH (inactive) within 3 sec.)
  • Causes:

    • The polygon mirror motor PCB connector is loose, broken, or defective
    • Polygon mirror motor PCB defective
    • Polygon mirror motor defective
    • IPU defective

  • Code: 204
  • Description: Polygon mirror motor error 3: XSCRDY signal error
    The polygon mirror motor "Ready" signal went inactive (HIGH) while the motor was operating at normal speed, even though the motor was neither switched off nor was there a request for a change in speed.
  • Causes: • Electrical oise interference on the line with the motor signals
    • Polygon mirror motor PCB connector loose, broken, defective
    • Polygon mirror motor PCB defective
    • Polygon mirror motor defective
  • Code: 205
  • Description: Polygon mirror motor error 4: Unstable timeout
    The "Ready" signal (XSCRDY) was detected as unstable for more than 20 sec. while the polygon mirror motor was operating at normal speed.
  • Causes: • Electrical noise on the line with the motor signals
    • Polygon mirror motor PCB connector loose, broken, defective
    • Polygon mirror motor PCB defective
    • IPU defective
  • Code: 220
  • Description: Laser synchronization detection error
    The 1st laser synchronization detection unit could not detect the line synchronization signal (DETP0) within 500 ms while the polygon mirror motor was operating at normal speed. Note: The unit polls for the signal every 50 ms. This SC is issued after the 10th attempt fails to detect the signal.
  • Causes: • Laser synchronization board connector loose, broken, defective
    • Laser synchronization detection board is not installed correctly (out of alignment)
    • Laser synchronization board defective • IPU defective
  • Code: 300
  • Description: Charge corona output error
    The feedback voltage from the charge corona unit is detected too high 9 times
  • Causes: • Charge corona power pack defective
    • Charge corona harness disconnected
    • Poor charge corona unit connection
  • Code: 303
  • Description: Charge corona grid leak
    When the high voltage is output to the corona grid, feedback voltage exceeds the prescribed value 9 times.
  • Causes: • Charge corona power pack defective
    • Charge corona harness disconnected • Poor charge corona unit connection
  • Code: 304
  • Description: Charge grid circuit open
    When high voltage goes to the corona grid, feedback voltage is more than the set value 9 times. This feedback voltage is used to update PWM for output control.
  • Causes: • Charge corona unit defective or disconnected
    • Charge corona harness defective
    • Charge corona power pack is defective.
  • Code: 305
  • Description: Charge corona wire cleaner error 1
    The charge cleaner pad does not arrive at the home position:
    • Motor locked within 4 s after switching on, or does not lock within 30 s.
    • Motor locked within 10 s after reversing, or does not lock within 30 s.
  • Causes: • Charge corona wire cleaner motor defective
    • Motor driver defective
