Media Path Cleaning
Use a cleaning swab and/or a lint free cloth to remove debris, dust or crust that has built-up on
the holders, guides and media path surfaces. Lightly moisten the swab or cloth with
99% solution
medical-grade alcohol. For hard to clean areas,
use extra alcohol on a cleaning swab to soak the
debris to break up any adhesive that may have accumulated on surfaces in the media
compartment.
Do not clean the printhead, movable sensor, or platen as part of this process.
1. Pull the two (2) Release Arms out to release the Ribbon Drive Transport. The arms are
located on the left and right sides of the printer. The Ribbon Drive Transport and Printhead
Actuator Arm will now be loose.
2. Swing the Printhead Actuator Arm up until it touches the printer’s top cover. Hold the
Printhead Actuator Arm in this position for access to the area below the printhead, see the
next graphic.
