  • Code: C4001
  • Description: Faulty HSYNC
    - The SOS sensor does not detect a rising edge of SOS within a given period of time after the polygon motor has started turning and a laser output has been started.
    - The SOS sensor detects no rising edges of SOS while VIA (image area control) is ON.
  • Remedy: 1 Turn OFF and ON the power switch. 2 Check the connector between PH unit- PRCB CN1, CN2 for proper connection and correct as necessary. 3 Change PH unit. 4 Change PRCB.
  • Code: C4101
  • Description: Polygon motor malfunction
    - A HIGH polygon motor lock signal is not detected within a given period of time that begins 0.5 sec. after the polygon motor has started turning.
    - A LOW polygon motor lock signal is not detected for a continuous given period of time while the rotation of the polygon motor remains stabilized.
  • Remedy: 1 Turn OFF and ON the power switch. 2 Check the connector between PH unit- PRCB CN1, CN2 for proper connection and correct as necessary. 3 Change PH unit. 4 Change PRCB.
