Chapter 1616-916.2.2 Detail in E602 0011-1102iR7105 / iR7095 / iR7086XX= "00"0001 The version of the language file on the HDD and that of bootable do notmatch.Update the version of the language file (Language), or installthe appropriate file.0002 The language file on the HDD is too large.0003 There is no language to which a switchover is made as described in the Configfile on theHDD.0004 An attempt to switch over to the language described in the Config file on theHDD fails.1000 The connected boot ROM is not one designed for the model in question. Replace the boot ROM.2000 An illegal engine ID has been detected. Reinstall the system software.E746 An unsupported optional board has been detected.0003 The option board that has been detected is one deigned for a different model. Replace it with one for the model in question.E748 Main controller PCB error4910 Indicates that a different model of the main controller PCB is detected.(The main controller PCB differs for 105-sheet model (iR7105) and 95-sheetmodel/86-sheet model (iR7095 / iR7086).)Replace to the appropriate main controller PCBE749 Restart in accordance with a change of the product configuration0001 A boot ROM designed for a different model has been fitted in place (as wheninstallingan PDL option).There is no need for remedial action. Nevertheless, the factwill remain as part of theerror history.E800 The auto power-off circuit has an error.An open circuit has been detected for 3 sec or more in the auto power-offcircuit.Turn off and then on the power. Disconnect and then connectJ505 of the DC controller PCB.Disconnect and then connect J1719 of the relay PCB. Replacethe relay PCB. Replace theDC controller PCB.E804 The rotation of the following is faulty: power supply cooling fan 1, power supply cooling fan2, controller cooling fan.0001 The fan stop signal has been detected for 5 sec or more after the power supplycooling fan 1has gone on.Disconnect and then connect J505 of the DC controller PCB.Replace the power supplycooling fan 1. Replace the DC controller PCB.0002 The fan stop signal has been detected for 5 sec or more after the power supplycooling fan 2has gone on.Disconnect and then connect J505 of the DC controller PCB.Replace the power supplycooling fan 2. Replace the DC controller PCB.0004 The fan stop signal of the controller cooling fan has been detectedcontinuously for 16 sec.Disconnect and then connect J1028 of the main controllerPCB. Replace the controllercooling fan. Replace the main controller PCB.E805 The fixing heat discharge fan rotation is faulty.0002 The fan stop signal has been detected for 5 sec or more after the fixing heatdischarge fanhas gone on.Disconnect and then connect J503 of the DC controller PCB.Replace the fixing heatdischarge fan. Replace the DC controller PCB.E820 The drum fan rotation is faulty.0000 The fan stop signal has been detected for 5 sec or more after the drum fan hasgone on.Disconnect and then connect J512 of the DC controller PCB.Replace the drum fan. Replace the DC controller PCB.E823 The pre-transfer charging assembly fan rotation is faulty.0000 The fan stop signal has been detected for 5 sec or more after the pre-transferchargingassembly fan has gone on.Disconnect and then connect J504 of the DC controller PCB.Replace the pre-transfercharging assembly fan. Replace the DC controller PCB.E840 An HP detection error has occurred in relation to the fixing inlet sensor (fixing wrap jamdetection).0000 The home position is not detected when he sensor is moved up/down (i.e., thesensorhas not gone on).Disconnect and then connect J508, J552, and J553 of the DCcontroller PCB. Disconnectand then connect J4001 and J4002 of the fixing inlet sensorascent/descent motor driverPCB; as necessary, replace the fixing inlet sensor ascent/descent motor. Replace the fixinginlet sensor ascent/descent motor driver PCB.0001 The home position is not detected when the sensor is moved up/down (i.e., thesensorhas not gone off).E850 There is a fault in the double-feeding detection unit.0000 The double-feeding sensor (reception) fails to attain an ultrasonic signal of aspecificlevel.Remove paper lint form the surface of the double-feedingsensor (reception). Remount thedouble-feeding sensor (transmission, reception). Disconnectand then connect J509 andJ550 of the DC controller PCB. Replace the double-feedingsensor (transmission, reception).Replace the double-feeding sensor PCB (transmission,reception).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).
