Zebra recommends that you clean the printhead when you load a new roll of media.
  1. Rub the cleaning pen across the dark area of the printhead. Clean from the middle to the outside, to move adhesive transferred from the edges of media out and away from the media path.
  2. Wait one minute before you close the printer to allow the wet areas to dry fully.
