Error Codes List page 3

  • Code: 2553
  • Description: Abnormally low toner density detected magenta TCR sensor
    When sampling data is determined in TC ratio calculation control, TCR sensor output is lower than a predetermined value for a predetermined number of times in a row even though there is toner in the toner cartridge.
  • Causes: • Imaging unit/C,M,Y,K • Toner supply motor/YM (M5) • Toner supply motor/CK (M6) • Printer control board (PRCB)
  • Remedy: 1 Perform image troubleshooting procedure if image density is low. - - 2 Reinstall the imaging unit - - 3 Check the connector between imaging unit-PRCB CN18, CN19 for proper connection and correct as necessary. - - 4 M5, M6 operation check PRCB CN22-1 to 4 (M5) PRCB CN22-5 to 8 (M6) 7-I 7-K 5 Replace the imaging unit - - 6 PRCB F5 conduction check - - 7 Replace PRCB
  • Code: 2554
  • Description: Abnormally high toner density detected magenta TCR sensor
    TC ratio in the imaging unit, which is determined by toner replenishing amount control mechanism, is a predetermined value or more for a given number of times consecutively
  • Causes: • Imaging unit/C,M,Y,K • Printer control board (PRCB)
  • Remedy: 1 Reinstall imaging unit - - 2 Check the connector between imaging unit-PRCB CN18, CN19 for proper connection and correct as necessary. - - 3 Replace the imaging unit - - 4 Replace PRCB
  • Code: 2555
  • Description: Abnormally low toner density detected yellow TCR sensor
    When sampling data is determined in TC ratio calculation control, TCR sensor output is lower than a predetermined value for a predetermined number of times in a row even though there is toner in the toner cartridge.
  • Causes: • Imaging unit/C,M,Y,K • Toner supply motor/YM (M5) • Toner supply motor/CK (M6) • Printer control board (PRCB)
  • Remedy: 1 Perform image troubleshooting procedure if image density is low. - - 2 Reinstall the imaging unit - - 3 Check the connector between imaging unit-PRCB CN18, CN19 for proper connection and correct as necessary. - - 4 M5, M6 operation check PRCB CN22-1 to 4 (M5) PRCB CN22-5 to 8 (M6) 7-I 7-K 5 Replace the imaging unit - - 6 PRCB F5 conduction check - - 7 Replace PRCB
  • Code: 2556
  • Description: Abnormally high toner density detected yellow TCR sensor
    TC ratio in the imaging unit, which is determined by toner replenishing amount control mechanism, is a predetermined value or more for a given number of times consecutively
  • Causes: • Imaging unit/C,M,Y,K • Printer control board (PRCB)
  • Remedy: 1 Reinstall imaging unit - - 2 Check the connector between imaging unit-PRCB CN18, CN19 for proper connection and correct as necessary. - - 3 Replace the imaging unit - - 4 Replace PRCB
  • Code: 2557
  • Description: Abnormally low toner density detected black TCR sensor
    When sampling data is determined in TC ratio calculation control, TCR sensor output is lower than a predetermined value for a predetermined number of times in a row even though there is toner in the toner cartridge.
