Chapter 1616-50001 An open circuit of the counter signal has been detected. Disconnect and then connect J1022 of the main controllerPCB. Replace the copy datacontroller/NE controller. Replace the main controller PCB.E043 The rotation of the pickup motor of the side paper deck is faulty.0000 The side paper deck pickup motor has gone on, but the PLL lock signal is notdetected for 2sec or more (1st detection).MEMO:For the 2nd and subsequent detection, the machine will indicate "E043" on thescreenoffering a choice of sources of paper.Disconnect and then connect J101 and J106 of the side paperdeck driver PCB. Replace thepickup motor. Replace the side paper deck driver PCB.Replace the DC controller PCB.E051 The horizontal registration HP detection has an error.0001 After the start of horizontal registration HP detection, the HP sensor is not offwithin 5 sec(i.e., not leaving home position).MEMO:If an error is detected in the course of horizontal registration HP detection atpower-on, themachine will indicate the presence of a jam.At the start of horizontal registration detection in the courseof printing, the horizontalregistration detection operation for downstream paper doesnot end within 5 sec.0002 After the start of horizontal registration HP detection, the home position is notdetectedwithin 5 sec.MEMO:If an error is detected in the course of horizontal registration HP detection atpower-on, themachine will indicate the presence of a jam.0003 Replace the horizontal registration HP sensor. Replace the horizontalregistration motor.Replace the stackless transport driver PCB. Replace the DC controller PCB.E065 The high-voltage output has a fault. (primary charging assembly)0000 A fault (leak) is detected when high voltage is supplied to the primarycharging assembly.Remove and then mount the primary charging assembly.Check for soiling. Disconnect andthen connect T601, J723, and J731 of the HV-DC PCB.Replace the HV-DC PCB.E067 The high-voltage output has a fault.0000 A fault is detected at the same time in 2 of the following: primary high voltage,pre-transferhigh voltage, transfer high voltage, separation high voltage.Remove and mount the primary charging assembly. Removeand mount the pre-transfercharging assembly. Remove and mount the transfer/separation charging assembly.Disconnect and then connect J721, J723, J731, and J734 ofthe HV-DC PCB. Replace theHV-DC PCB. Replace the HV-AC PCB.E068 The high-voltage output has a fault. (separation charging assembly)0000 A fault (leak) has been detected while the separation charging assembly isbeing suppliedwith high voltage.Remove and mount the transfer/separation chargingassembly. Disconnect and then connectJ7233 and J734 of the HV-DC PCB. Disconnect and thenconnect J741 and J742 of theHV-AC PCB. Replace the HV-AC PCB. Replace the transfer/separation charging assembly.Replace the pre-transfer charging assembly.E069 The transfer high voltage has an error.0000 A fault (leak) has been detected while the transfer charging assembly is beingsupplied withhigh voltage.Remove and mount the transfer/separation chargingassembly. Check for soiling.Disconnect and then connect T701 and J723 of the HV-DCPCB. Replace the HV-DC PCB.Replace the pre-transfer charging assembly.E102 A read error has occurred in relation to the laser scanner unit EEPROM data.0001 The correction data cannot be read from the EEPROM of the laser scannerunit.Disconnect and then connect the connector of the video PCB.Disconnect and then connectthe DC controller PCB. Replace the laser scanner unit.E110 The laser scanner motor rotation has a fault.0000 After the laser scanner motor has gone on, the PLL lock signal of the motor isnot detectedfor 15 sec or more.Check to see if all covers have been attached to the primarycharging assembly. Disconnectand then connect J764 of the laser scanner motor drive PCB(in the laser scanner unit).Disconnect and then connect J1401 of the video PCB.Disconnect and then connect J506 ofthe DC controller PCB. Replace the laser scanner unit.Replace the video PCB. Replace theDC controller PCB.E111 The laser scanner motor cooling fan rotation has a fault.0000 After the laser scanner motor cooling fan has gone on, the fan stop signal isdetected for 5sec or more.Disconnect and then connect J503 of the DC controller PCB.Replace the laser scannermotor cooling fan. Replace the DC controller PCB.E121 A fault exists in the rotation of the following: laser scanner unit cooling fan, reader heatdischarge fan 1, reader heat discharge fan 2.Code Description Remedial action*: model equipped with DADF-Q1 (outside Japan, iR7105/7095; inside Japan: iR7105/7095/7086).**: model equipped with DADF-M1 (outside Japan: iR7086).
