After replacing the DADF/scanner assembly, adjust the contact image sensor (CIS) for the front and back.

Because of differences in each individual DADF/scanner assembly, go into the SP mode, and enter the values on the barcode on the assembly to adjust the difference in the color balance between front and back.

Be sure to perform this adjustment each time you replace the DADF/scanner assembly.

  1. Check the barcode.

     

    • The barcode values are, from the left, red (3), green (3), blue (3), gray (2), 0, 0, 0, 0.


  2. Enter the Maintenance Mode Menu.
  3. Press [Scanner Service Setting].


  4. Press [Image Adjust].
