Correcting the Reading Sensor

Depending on the characteristics of the media, such as reflectivity and colors, the machine may not be able to read the crop marks. In such cases, correct the sensor for reading crop marks. If you are not cutting with crop marks, operation is not affected even if a failure is displayed.
Procedure
  1. Set up the media.
  2. Tap AP-640_Panel_Icon_MENU.
  3. Tap Media Settings - Other Media Settings - Multi Sensor Adjustment.
  4. Tap Execute.
    The Adjustment Result screen appears.
    • Successful:

      Tap AP-640_Panel_Icon_HOME to go back to the original screen.

    • Failed:

      Check the following items.

      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 due to the characteristics (reflectivity and colors) of the media. To cut with crop marks, change the media.
      There is ink on the multi sensor because, for example, the media strikes it immediately after printing. Contact your authorized Roland DG Corporation dealer.
