First try printing a few pages to try and clean the drum unit. If the problem is not solved after printing a few pages, the drum unit may have glue from a label stuck on the drum surface.

      Keep the Cancel and Back buttons pressed down until "DRUM CLEANING" is displayed on the LCD.

      The paper will feed into the printer to start the drum cleaning.
    7. When "DRUM CLEANING / COMPLETED" is displayed on the LCD, press the Cancel button.

      We recommend this cleaning operation once a month to keep the best quality.
