1.  Remove the upper paper guide [A] of the lift cover.

  2. Remove the bracket [A].
  3. Disconnect the harness of the separation sensor [A] and Skew correction sensor [B].
  4. Remove the harness [A] from the upper paper guide.
    Discard the removed harness. Do not keep it.
  5. Prepare the supplied long harness [A], and then connect it to the double-feed sensor (receiver) [B], and connect to the sensors removed in step 3.
    Since both separation sensor and skew correction sensor connectors are 3 pins, they are identified by color (black and white). Connect as shown below.

  6. Install the double-feed sensor (receiver) [A] to the upper paper guide.
    Fit the bracket to the positioning projection and then screw it.
  7. Route the harness as shown below and let it through the hook.
    Also, adjust the length so that the binding part [A] comes to the position just before the hook.
  8. Attach the supplied small clamp [A] to the bracket removed in step 2.
  9. Reattach the bracket [A] to the upper paper guide.Pass the harness of the double-feed sensor (receiver) through the clamp.
  10.  Pass the harness of the double-feed sensor (receiver) through the clamp.
    Make sure that the bearings [B] of the bracket [A] is fixed to the guide.
  11. Reattach the sensor bracket [A].
    Let the harness through the hook and adjust the length so that the binding part [B] comes to the position just before the hook.
  12. Confirm the routing of the harness.
    Whether the harness and the ground wire of the double-feed sensor are on the front side of rib [A].
    Whether the position of the bind parts are correct.
    Whether the harness goes through a hook.
  13. Clean the area [A] on side of rib with alcohol.

     
  14. Prepare the supplied plastic sheet [A], and fit the groove (red circle below) to the bracket as shown below.
  15. Push the plastic sheet to all the way in the unit it stops.
  16.  Align the plastic sheet to the top (red line) of the rib, then peel off the double-sided tape [B] on the back of the plastic sheet and affix it to the side of the rib.
  17.  Attach the upper paper guide [A].
    Confirm that there is no entrapment of the harness at the position [B].
