Learn how to resolve a jammed print head on the mailstation and mailstation2.
Products affected: mailstation™, mailstation2™


Your print head jams and does not move into the printing position.


  • A piece of black Mylar inside the machine is dislodged and blocking the printer.
  • The clear plastic piece that covers the white cable on the lid is not in the proper position.
  • The envelope sensor is not in the proper position.


  1. Check to see if the black Mylar piece inside of the meter (shown in the following picture) is blocking the print head. This piece can become dislodged or broken and block the print head path. If it is, remove it from the meter. To remove, press down on the center of the Mylar and pull up and out of the meter.
