  2. Tap AP-640_Panel_Icon_MENU.
  3. Tap Media Settings - Other Media Settings - Multi Sensor Adjustment.
  4. Tap Execute.
  5. Perform the operations shown below according to the Adjustment Result.
    • If Successful is displayed on the operation panel, proceed to the next procedure.
    • If Failed is displayed on the operation panel, the following causes are possible, so take countermeasures and redo the correction.
      Cause Countermeasures

      The lighting in the room where the printer is installed or vicinity of the printer is too bright.

      Adjust the lighting in the room.
      Correction failed for some reason. Redo the correction.
      Crop marks cannot be recognized on the media being used. Change the media type.
      There is ink on the multi sensor because, for example, the media strikes it immediately after printing. Contact your authorized Roland DG Corporation dealer.
