For the correspondence between the cables, FFCs and the connectors on the Main Board, see
When routing the Scanner motor cable (CN32), ADF document sensor cable (CN72), ADF encoder sensor cable (CN73), Paper Support Encoder Sensor
cable (CN76), follow the procedure below.
• Insert the cables from the hole A on the Housing Upper and route them through the hook B, rib A (x2), and rib B (x3) on the Frame Base 1st, then route
them inside the rib C and connect them to their connectors on the Main Board.
• Set the ferrite core A of the Scanner Motor cable as shown above.
Route the ADF motor cable (CN33), ADF PE sensor cable (CN71), ADF Plunger cable (CN77), and Scanner Open Sensor cable (CN74) as shown below.
• Insert the cables from the hole A on the Housing Upper and route them through the hook A and the slit on the Frame Base 1st, then connect them to their
connectors on the Main Board.
• Set the ferrite core B of the ADF Motor cable as shown above.
Insert the Grounding Wires (x3) from the hole A on the Housing Upper, and secure them at the position shown above with the screw.
Route the Scanner FFC as follows.
1. Insert it into the hole B of the Housing Upper, and route under the rib D of the Housing Upper.
1. Thread the Scanner FFC through the ferrite core C, and secure the ferrite core C to the position shown above with double-sided tape.
2. Secure the Scanner FFC on the position shown above with double-side tape, and then connect the FFC to the connector (CN70) on the Main Board.
Put the excess portion of the cables after routing into the space between the Housing Upper and Main Board.
