Cleaning the Printhead – ZD421 Ribbon Cartridge Printers

Zebra recommends that you clean the printhead when you load a new roll of media.
  1. Pull the two release arms out to release the ribbon drive transport. For instructions on how to access the printhead, see Accessing the Printhead of the ZD421 Ribbon Cartridge Printer.
  2. Lift the printhead actuator arm up to access the printhead.
  3. Rub the cleaning pen across the dark area of the printhead. Make sure you clean from the middle to the outside. This moves adhesive transferred from the outer edges of media away from and outside the media path.
  4. Wait one minute for the surface of the printhead to dry.
  5. Release the printhead actuator arm, then push the ribbon drive transport into the printhead actuator arm.
    The release arms snap into place, relinking the ribbon drive transport to the top cover and the printhead actuator arm.
