      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.
      The media being used cannot be recognized. Change the media type.
      There is ink on the multi sensor because, for example, the media strikes it immediately after printing. Contact your authorized dealer.
