1. Remove the DF unit. (Document Feeder)
  2. Remove the scanner front cover. (Scanner Front Cover)
  3. Remove the scanner top cover. (Scanner Top Cover (Left Scale, Top Scale, Exposure Glass, Sheet-through Glass))
  4. Remove the front CIS in the scanner unit. (CIS in the Scanner (Original Front Side CIS))
  5. Press the pulley, and then remove the timing belt [A] by bending it.

  6. Remove the double-sided adhesive tape [A] on the FFC, and then remove the FFC from the carriage.

  7. Remove the double-sided adhesive tapes [A] and [B] from the scanner base.

  8. Disconnect the FFC [A] from the machine’s rear.

Attaching the Sponge and Ferrite Cores When Replacing the FFC on the Scanner Unit

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

Attach them as follows.

 

  1. Pass the FFC through the ferrite cores [A].
  2. Attach the sponge along the line [a] on the FFC.

[C]: 1mm
[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.

Attach the double-sided adhesive tape here.
