Chapter 77-44F-7-1197.10.17.3 When Replacing the Potential Sensor/PotentialControl PCB 0011-8746iR7105 / iR7095 / iR7086The machine remains powered after the main power switch is turned off aslong as the power plug is connected to the power outlet. Be sure to discon-nect the power plug from the power outlet.1) Turn off the power.2) Remove the developing assembly, and slide out the process unit.3) Disconnect the connector [1] of the potential sensor.F-7-1204) Remove the 2 screws [1], and detach the potential sensor support plate [2].F-7-1215) Put back the developing assembly and the process unit.6) Connect the connector [1] of the potential sensor.F-7-1227) Fit the potential checker electrode (FY9-3041) [2] to the potential sensor[1].F-7-123When fitting the checker electrode to the potential sensor, make sure that themagnet of the checker electrode will not come into contact with the potentialsensor cover.8) Connect the cable [1] of the potential sensor checker electrode to theframe assembly (GND) [2] of the machine.Never bring the clip into contact with the sensor cover. Be sure to fit it fullyaway from the sensor window.F-7-1249) Fit the door switch actuator to the door switch assembly [1] and the lasershutter assembly [2].10) Turn on the powor.11) Execute the following service mode items:COPIER > FUNCTION > DPC > OFST12) Record the value of on the service sheet.13) Turn off the main power switch.14) Detach the potential sensor checker electrode.15) Put back the potential sensor support plate.16) Turn on the power.7.10.18 Dust-Collecting Roller7.10.18.1 Removing the Dust-Collecting Roller 0010-8885iR7105 / iR7095 / iR70861) Remove the pre-transfer charging assembly.2) Remove the two screws [1], and detach the motor cover [2].[3][2][1][1][1][2][1][1][1][2][1][2]
