  8. Remove the fan motor [A] from the bracket [B].
  9. Remove the spring plate [B] and the resistor harness [C] from the bracket [A].
  10. Assemble the fan motor [A] and bracket [B] (for Finisher SR4110) (accessory #10).
  11. Remove the knob screw [C] and snap ring [B] from the upper cover [A] removed from the cooling fan unit in step 1.
  12. Remove the air shield [B] from the upper cover [A].
  13. Remove the bracket [B] from the air shield [A].
  14. Assemble the air shield [A] and Upper Cover (for Finisher SR4110) [B] (accessory #12) with the snap ring and knob screw removed in step 11.
  15. Attach the spring plate [B] removed in step 9 to the Lower Cover (for Finisher SR4110) (accessory #11) [A].
  16. Prepare the following parts:
    • Rocker switches [A] and [B]
    • Harness removed in step 9 [C]
    • Lower cover of Finisher SR4110 [D]

  17. Route the harnesses through the openings [D], and attach the rocker switches [B] and [C] to the lower cover of Finisher SR4110 [A].

    • Attach the rocker switch [B] so that the white dot is to the side indicated with the arrow in the photo below.
    • Attach the rocker switch [C] so that the side connected with the harness corresponds to the direction of the arrow shown in the photo below.

  18. Insert the resistor harness [A] into the spring plate [B].
  19. Connect the connectors [A] and [B].
  20. Connect the 2 connectors [A] to the rocker switch [B].
  21. Remove the clamp [B] from the bracket [A] removed in step 7. Then attach the clamp [B] to the hole [C] in the lower cover of Finisher SR4110.
  22. Remove the jogger unit cover [A] from Finisher SR4110.
  23. Mount the fan motor unit on Finisher SR4110 by aligning the hooks [A] and [B] with the cutouts [C] and [D].

  24. Attach the lower cover [A] assembled in step 21 by inserting the tabs [B] and [C] into the grooves [D] and [E] located under the cooling fan unit.

    • Grooves [D] and [E] refer to the wider groove (towards the upstream direction from the unit).

  25. Connect the connectors [A] and [B].
  26. Fix the harness [A] from the interface unit mounted on the copier in Preparing the Main Machine.
    (Ground wire [B], bracket [C], and connector [D])
  27. Clamp the harness.
  28. Mount the upper cover [A] assembled in step 14 on the cooling fan unit.

  29. Bind the harness of the interface unit [A] and clamp it with Locking Wire Saddle CKN-13 [B] (accessory #4).

    • Depending on the number of options installed between the copier and Finisher SR4110, 3 pcs of Locking Wire Saddle CKN-13 might be needed to clamp the harness.
