KIP 7570

• Code: E-0322h, E-802
• Description: Abnormal output of Process 1 Separation Charger
• Causes: The Separation Corona Output Detection Signal (AC_LD) continues to be “L” for 1 second or longer when the Separation Corona is ON.
• Remedy: Wires 1 Are wires among Image Corona, HV Power Supply PCB and PW14420 PCB connected properly? No Connect them properly.
  Image Corona 2 Is the Image Corona dirty? Yes Clean each Corona Wire, Grid Plate and housing.
  Cleaning Roller 3 Does the bias terminal plate touch to Cleaning Roller shaft properly? No Remove and reapply conductive grease to Cleaning Roller shaft. Relocate the bias terminal plates properly. Is grease applied enough? No Remove and reapply conductive grease to Cleaning Roller shaft.
  Transfer Corona 4 Is the Transfer Corona dirty? Yes Clean each Corona Wire and housing. Is the Corona Wire broken? Yes Replace the Corona Wire.
  Separation Corona 5 Is the Separation Corona dirty? Yes Clean each Corona Wire and housing. Is the Corona Wire broken? Yes Replace the Corona Wire.
  HV Power Supply 6 Can you fix the problem if you replace the HV Power Supply? Yes OK

• Code: E-0323h, E-803
• Description: Abnormal output of Process 1 Developer Bias
• Causes: Due to abnormality of Developer, Cleaning Roller or HV Power Supply PCB, Bias Output Detection Signal (BIAS_LD) continues to be “L” for 1 second or longer when a specified bias is supplied to the corresponding Developer Unit components.
• Remedy: Wires 1 Are wires among Developer Unit, HV Power Supply PCB and PW14420 PCB connected properly? No Connect them properly.
  Developer Unit 2 Is the toner spill out from the Developer Unit? (Or is there any similar problem?) Yes Clean each Corona Wire, Grid Plate and housing. Is the high voltage of Regulation Roller leaking? (The resistance between the central part of Regulation Roller and the Ground is 5 mega ohm or smaller if leaking.) Yes Replace the Regulation Roller.
  Cleaning Roller 3 Is Copper Plate pressed to the shaft of Cleaning Roller for secure contact? No Deform the Copper Plate a little by hand so that it surely presses the shaft. Remove old conductive grease and apply new one. Is there enough conductive grease? No Remove old conductive grease and apply new one.
  HV Power Supply 4 Can you fix the problem if you replace the HV Power Supply? Yes OK

• Code: E-0330h, E-816
• Description: Process 1 LED Printhead 1 Error
• Causes: FPGA fails in transferring an adjustment data to the left block of LED Head after turning on the printer.
• Remedy: Wires 1 Are the wires between LED Head and PW14420 PCB connected properly? No Connect them properly.
  LED Head 2 Can you fix the problem if you replace LED Head? Yes OK
  PW14420 PCB 3 Can you fix the problem if you replace PW14420 PCB? Yes OK

• Code: E-0331h, E-817
• Description: Process 1 LED Printhead 2 Error
• Causes: FPGA fails in transferring an adjustment data to the central block of LED Head after turning on the printer.
• Remedy: Wires 1 Are the wires between LED Head and PW14420 PCB connected properly? No Connect them properly.
  LED Head 2 Can you fix the problem if you replace LED Head? Yes OK
  PW14420 PCB 3 Can you fix the problem if you replace PW14420 PCB? Yes OK

• Code: E-0332h, E-818
• Description: Process 1 LED Printhead 3 Error
• Causes: FPGA fails in transferring an adjustment data to the right block of LED Head after turning on the printer.
• Remedy: Wires 1 Are the wires between LED Head and PW14420 PCB connected properly? No Connect them properly.
  LED Head 2 Can you fix the problem if you replace LED Head? Yes OK
  PW14420 PCB 3 Can you fix the problem if you replace PW14420 PCB? Yes OK

• Code: E-0335h, E-821
• Description: Process 1 Density Sensor Error
• Causes: The default output of Density Sensor reaches less than 0.1V or more than 1.3V.
• Remedy: Wires 1 Is the wire between Toner Density Sensor and PW14420 PCB connected properly? No Connect it properly.
  Density Sensor (PH11) 2 Can you fix the problem if you replace Density Sensor? No Replace PW14420 with a new one.
