Causes: When the Auto SP Control fails in adjusting the surface potential to within the acceptable range.
Remedy: Harness 1 Is the harness connected to Surface Potential Sensor (SPS1) and Main Control PCB? No Connect it. Image Corona Or Drum 2 Set the Auto SP Control to OFF, turn off/on the KIP9000, and take printing. Is any abnormal image printed, such as “too dark”, “with dark background” and “too light”? No 1. Reinstall the Image Corona correctly. 2. Replace the Drum. Surface Potential Sensor (SPS1) 3 Can the error be fixed by replacing the Surface Potential Sensor? Yes OK (Set the Auto SP Control back to ON, and turn off/on the KIP9000.) Main Control PCB (PW11520) 4 Can the error be fixed by replacing the Main Control PCB? Yes OK (Set the Auto SP Control back to ON, and turn off/on the KIP9000.)
Code: E-27
Description: Density Sensor Error
Causes: When the initialization of Density Sensor could not be achieved successfully during Density Lock process.
Remedy: Harness 1 Is the harness connected to the Density Sensor? No Connect it. Density Sensor Or LED Head 2 Is the Density Sensor or LED Head dirty with toner? No Clean them. Density Sensor (PH44) 3 Can the error be fixed by replacing the Density Sensor? Yes OK Main Control PCB (PW11520) 4 Can the error be fixed by replacing the Main Control PCB? Yes OK
Code: E-28
Description: Density Control Error
Causes: When the Auto Density Control fails in adjusting the density to within the acceptable range.
Remedy: Harness 1 Is the harness connected to Density Sensor and Main Control PCB? No Connect it. Density Sensor Or LED Head 2 Is the Density Sensor or LED Head dirty with toner? No Clean them. Density Sensor (PH44) 3 Can the error be fixed by replacing the Density Sensor? Yes OK Main Control PCB (PW11520) 4 Can the error be fixed by replacing the Main Control PCB? Yes OK
Code: E-30
Description: Developer Disconnection Error
Causes: When the connector in Process Unit is disconnected.
Remedy: Harness 1 Is the connector J84 connected? (Is another end of this cable connected to Main Control PCB?)) No Connect it. Main Control PCB (PW11520) 4 Can the error be fixed by replacing the Main Control PCB? Yes OK
Code: E-43
Description: RFID (IC Tag) Error
Causes: When the FRID PCB is defective
Remedy: Harness 1 Is the harness connected to each RFID PCB and Main Control PCB? No Connect it. RFID IC Tag Reader & WriterPCB 3 Can the error be fixed by replacing the RFID PCB? Yes OK Main Control PCB (PW11520) 4 Can the error be fixed by replacing the Main Control PCB? Yes OK
Code: E-49
Description: Developer Positioning Motor Error
Causes: Home position of Developer Unit can not be detected although 60 seconds has passed since the Developer Positioning Motor had started the positioning operation.
Remedy: Harness 1 Is the harness connected to the Developer Positioning Motor? No Connect it. Developer Positioning Motor (M4) 2 Can the Developer Positioning Motor (signal code : 68) be operated properly in the Function Checking Mode of Service Mode? No Replace the Developer Positioning Motor. Yes Reinstall Developer Unit Position Sensor, Sensor Disc and Cam correctly. DC Driver PCB (PW7755) 3 Can the error be fixed by replacing the DC Driver PCB? Yes OK Developer Unit Position Sensor (PH25) 4 Check the input signal from the Developer Unit Position Sensor (signal code 2b) in the Input/Output Checking Mode of Service Mode. Is the status “L” when the Developer Unit is at the Home Position and “H” when the unit is not at the Home Position? No Replace the Developer Unit Position Sensor. Main Control PCB (PW11520) 5 Can the error be fixed by replacing the Main Control PCB? Yes OK
