Correct the color deviation of the CIS after replacing the ADF unit or CIS unit. 

  1. Perform the registration adjustment of the ADF (back side). (ADF Side-to-Side and Leading Edge Registration)
  2. Print an ACC test pattern.
    [User Tools] icon > [Machine Features] > [Maintenance] > [Auto Color Calibration] > [Copier Function] > [Start] > [Start Printing]
  3. Press [Stop].
    An error screen will be displayed if [Start Scanning] is pressed.
  4. Turn over the ACC test pattern [A] and set it on the ADF. (Set the arrow position of the test pattern in accordance with the arrow position of the photograph below.)
  5. Exit the User Tools mode, and then enter the SP mode.
  6. Execute SP4-958-001 (Read/Restore Std: Rear: Read New Chart).

  7. When the correction is completed successfully, [A] is displayed.

    If it failed, [B] will be displayed. Repeat steps 4 to 6.

The causes of the failure may be as follows.

  • The test pattern was not set correctly.
  • A jam occurred at the time of reading.
  • The ACC test pattern is abnormal (e.g. a pattern is missing).
  • The reading position has deviated (4mm or more) due to skewing for example.
