Chapter 77-43F-7-113Points to Note When MountingWhen mounting the separation claw holder, be sure that the separation clawholder spring is butted against the drum cleaner case. Further, check to makesure that the rack of the separation claw 3 drive assembly is engaged with thegroove in the separation claw holder.F-7-1147.10.17 Potential Sensor7.10.17.1 Removing the Potential Sensor Unit 0010-8881iR7105 / iR7095 / iR70861) Open the front cover.2) Remove the process unit.3) Push in the fixing/feeding assembly.4) Remove the cable guide [1].- 1 screw [2]5) Slide out the dust-blocking glass [3] to detach.6) Remove the potential sensor unit [4].- 1 connector [5]- 1 screw [6]F-7-115It is rather difficult to slide out the potential sensor unit in horizontal direc-tion. As shown, push it down before sliding it out to facilitate the work.F-7-1167) Remove the 2 screws [1], and detach the potential sensor cover [2]; then,detach thepotential sensor [3].F-7-117Be sure to replace the potential sensor at the same time as the potential con-troller PCB.When mounting it, fit the protrusion on the rear of the potential sensor stayin the hole of the side plate found at the rear of the machine; then, match iton the side plate found at the front to screw it in place.7.10.17.2 Removing the Potential Control PCB 0011-7609iR7105 / iR7095 / iR70861) Remove the primary charging assembly cover.2) Remove the process unit cover.3) Remove the double-feed detection PCB (receiving) if found.4) Remove the 2 screws [1], and disconnect the 2 connectors [2]; then, detachthe pre-transfer charging assembly fan [3].F-7-1185) Disconnect the 3 connectors [1], and remove the screw [2]; then, detachthe potential control PCB [3].[1][2]Separation claw holderRack[1][2][3][4][5][6][1][2][3][1] [3][2]
