 For the correspondence between the cables, FFCs and the connectors on the Main Board, see “ Main Board Unit (2) (p65)”.

 When routing the Scanner Motor cable (CN2), ADF PE Sensor cable (CN18), ADF Encoder cable (CN19), ADF Document Sensor cable (CN22), ADF

Motor cable (CN24), ADF grounding wire and scanner grounding wire, follow the procedure below.

1. Insert all cables into the hole of the Housing Upper, and then route them under the rib A.

2. Secure the ADF grounding wire and scanner grounding wire together on the position shown above with the screw.

3. Route the Scanner Motor cable (CN2), ADF PE Sensor cable (CN18), ADF Encoder cable (CN19), ADF Document Sensor cable (CN22) and ADF Motor

cable (CN24) through the hook of the Frame Base Assy and route them inside the rib B (x8), and then connect them to the connectors on the Main Board.

4. Put the ferrite core A of the ADF Motor cable into the position shown above.

5. Insert the excess portions of the Scanner Motor cable, ADF PE Sensor cable, ADF Encoder cable, ADF Document Sensor cable and ADF Motor cable

into the space between the Housing Upper and Main Board.

6. Secure the Scanner Motor cable, ADF PE Sensor cable, ADF Encoder cable, ADF Document Sensor cable, ADF Motor cable, ADF grounding wire and

scanner grounding wire on the positions shown above with acetate tape.

 When routing the Scanner FFC, follow the procedure below.

1. Insert it into the hole B of the Housing Upper, and route under the rib A of the Housing Upper.

2. Route the Scanner FFC through the ferrite core B and insert the ferrite core B into the inside of the rib C of the Housing Upper, and then secure it with double-sided tape.

3. Secure the Scanner FFC on the position shown above with double-side tape, and then connect the FFC to the connector (CN41) on the Main Board.

 When routing the Paper Stopper Lever Sensor 2nd cable and grounding wire A, follow the procedure below.

1. Route the Paper Stopper Lever Sensor 2nd cable and grounding wire A through the groove 1 (x3) of the Paper Guide Stopper Assy 2nd and through the

hook A, and then insert them into the hole on the bottom of the 2nd Bin Base Assy.

(See Fig. 2.)

2. Pull out the Paper Stopper Lever Sensor 2nd cable and grounding wire A from the hole on the upper side of the 2nd Bin Base Assy, and route them as

follows.

(See Fig. 3.)

• Grounding wire A Route it through the hook B and hook C of the 2nd Bin Base Assy.

• Paper Stopper Lever Sensor 2nd cable Route it through the hook B of the 2nd Bin Base Assy, and then make one turn around the hook C.

3. Install the Frame Pickup Assy to the 2nd Bin Base Assy, and secure the grounding wire A to the Frame Pickup Assy with the screw (x1).

(See Fig. 4.)

 Route the Pickup Motor cable, Pickup Encoder FFC and grounding wire B as follows. (See Fig. 4.)

• Pickup Motor cable Route it through the hook C and groove 2, and put the ferrite core of it into the position shown above. Then, route the cable

through the groove 3 and route it through the hook C once again.

• Pickup Encoder FFC Secure it on the position shown above with double-sided tape.

• Grounding wire B Secure it on the Frame Pickup Assy with the screw, and route it through the hook C.

 Insert the Paper Stopper Lever Sensor 2nd cable, Pickup Motor cable, Pickup Encoder FFC and grounding wire B into the hole on the bottom of the Frame

Base Assy, and pull them out from the upper side of the Frame Base Assy.

(See Fig. 1, Fig. 5.)
