Remedy: Wires 1 Is the wire between Counter and PW12420 PCB connected properly? No Connect it properly. 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. DC Power Supply (DCP1) or Fuse 2 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

Remedy: Wires 1 Are wires among Image Corona, HV Power Supply PCB and PW12420 PCB connected properly? No Connect them properly. Is the Image Corona dirty? Yes Clean each Corona Wire, Grid Plate and housing. Image Corona 2 Is the Corona Wire broken? Yes Replace the Corona Wire. 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. Cleaning Roller 3 Is grease applied enough? No Remove and reapply conductive grease to Cleaning Roller shaft. Is the Transfer Corona dirty? Yes Clean each Corona Wire and housing. Transfer Corona 4 Is the Corona Wire broken? Yes Replace the Corona Wire. Is the Separation Corona dirty? Yes Clean each Corona Wire and housing. Separation Corona 5 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 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. Is the Image Corona dirty? Yes Clean each Corona Wire, Grid Plate and housing. Image Corona 2 Is the Corona Wire broken? Yes Replace the Corona Wire. 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. Cleaning Roller 3 Is grease applied enough? No Remove and reapply conductive grease to Cleaning Roller shaft. Is the Transfer Corona dirty? Yes Clean each Corona Wire and housing. Transfer Corona 4 Is the Corona Wire broken? Yes Replace the Corona Wire. Is the Separation Corona dirty? Yes Clean each Corona Wire and housing. Separation Corona 5 Is the Corona Wire broken? Yes Replace the Corona Wire.
