Causes: The Fuser Motor Output Detection Signal (HEATM_LD) continues to be "H" for 3 seconds or longer when the Fuser Motor is rotating.
Remedy: Wires 1 Is the wire between Fuser Motor and PW12420 PCB connected properly? No Connect it properly. DC Power Supply (DCP1) or Fuse 2 Confirm that the machine is turned on, and then check the voltage of the orange line (J220-4). Is it 24V? No Replace the DC Power Supply if there is no problem with the wires. Confirm that the machine is turned off, and then check whether or not each Fuse is broken. Is any Fuse broken? Yes Replace the Fuse. Fuser Motor (M2) 3 Check the operation of Fuser Motor in the Device Operation Mode of the Service Mode. Device Code : 01 (Fuser Motor) Does the Fuser Motor operate correctly? No Replace the Fuser Motor.
Code: E-012
Description: Developer Press Motor Error
Causes: The Developer Press Sensor Signal (PRESS_S) does not change to "L" within 30 seconds after turning on.
Remedy: Wires 1 Are the wires among Developer Press Sensor (PH4), PW12420 PCB, Driver PCB B (PW6654) and Developer Press Motor (M4) connected properly? No Connect them properly. Developer Press Motor (M4) Driver PCB B (PW6654) 2 Turn off the machine, and then turn it on again. Is the Developer Unit moved to the Drum side? No Replace the Developer Press Motor or Driver PCB B. Developer Press Sensor (PH4) 3 Select the Signal Code “104” (Developer Press Sensor) in the Signal Status Mode, and then turn on the machine again. Does the status change from “H” to “L” after turning on? No Replace the Developer Press Sensor. Fuse 4 Does the fuse (F3) have a proper conductivity? No Replace the fuse (F3).
Code: E-020
Description: Counter Error
Causes: The Counter Connection Detection Signal (COUNT_OPN) continues to be "L" for 1 second or longer after turning on.
Remedy: Wires 1 Is the wire between Counter and PW12420 PCB connected properly? No Connect it properly. DC Power Supply (DCP1) or Fuse 2 Confirm that the machine is turned on, and then check the voltage of the orange line (J220-5). Is it 24V? No Replace the DC Power Supply if there is no problem with the wires. Turn off the machine. Does the fuse (F1) have a proper conductivity? No Replace the fuse (F1). Counter 3 Check the operation of Counter in the Device Operation Mode of the Service Mode. Device Code : 26 (Counter) Does the Counter operate correctly? No Replace the Counter.
Code: E-031
Description: Image Corona Output Error
Causes: The Image Corona Output Detection Signal (IM_LD) continues to be "L" for 1 second or longer when the Image Corona is ON.
Remedy: Wires 1 Are wires among Image Corona, HV Power Supply PCB and PW12420 PCB connected properly? No Connect them properly. Image Corona 2 Is the Image Corona dirty? Yes Clean each Corona Wire, Grid Plate and housing. Is the Corona Wire broken? Yes Replace the Corona Wire. 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-032
Description: Separation Corona Output Error
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 PW12420 PCB connected properly? No Connect them properly. Image Corona 2 Is the Image Corona dirty? Yes Clean each Corona Wire, Grid Plate and housing. Is the Corona Wire broken? Yes Replace the Corona Wire. 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-033
