1. Remove the DF rear cover. (DF rear cover)
  2. Disconnect the FFC.

  3. Remove the harness box [A].

  4. Release the FFC [A] from the harness guide.

  5. Remove the scanner rear right cover [A] while pressing down strongly with your thumb on the blue circle area.

  6. Remove the screw of the scanner rear cover.

  8. Remove the screw and pull out the FFC [A].

Attaching the Sponge and Ferrite Cores When Replacing the FFC on the SPDF

To replace the FFC, it is necessary to attach the sponges [A], [B] and ferrite cores [C].

Attach them as follows.

 

  1. Attach the sponge [A] along the edge of the mylar [B] on the FFC.
    [C]: 1mm
    [D]: Attach it within the width of the FFC.

  2. Attach the sponge.

    Align the edge of the sponge [A] with the positioning line [B] on the FFC and attach the sponge.

    [C]: 0 to 1 mm
    [D]: Attach it within the width of the FFC.

  3. Attach the spacer sponges within the parts framed in red [A] on the ferrite cores.

  4.  Pass the FFC through the ferrite cores [A].

  5. Align the edge of the sponge with the positioning line [B] on the printed side of the FFC.

    [C]: 0 to 1 mm

    [D]: Attach it within the width of the FFC.

 

If you forget to attach the sponge, the following problems may occur:

  • The proximity of the analog signals produces crosstalk so that, depending on the document, vertical streaks may appear on the scanned image.
  • Radio interference may be caused by contact with the metal plate.
