3.12.3 Media Mounting Considerations
The printer uses direct thermal media which is chemically treated to react to heat.
The printer has several basic requirements for running the media to the printer from a roll or
fan-fold media which include:
The printer uses direct thermal media which has been chemically treated to react to heat.
The printer has some basic requirements for the media to run successfully through the
printer.
• The centerline of the media roll or fan-fold stack should align with the center of the printer’s
paper path to provide the best tracking of the media and reduce media damage. A media
guide is required for printing accurately and consistently.
• Do not blow air onto the media.
Air should be pulled from the kiosk to keep out dust (which
shortens print head life and affects print quality) and chemicals (such as cleaning solutions
like ammonia or bleach). Air flow within the kiosk should not pull exhaust heat from other
kiosk components and power supplies across the media or printer.
• Avoid direct sunlight, incandescent or infrared lighting or heat sources. These light sources
can come from openings in the kiosk and other kiosk components. Incandescent light bulbs,
sun light and heat sinks are examples of heat sources that shouldn’t be near the printer or
media.
• The media path must be smooth and not cause excessive drag. It should be clear of
cables, other kiosk components, or surfaces other than media guides, supply holders or the
fan-fold media tray. Roll media must be able to turn with minimal resistance and allow the
printer to smoothly pull media without jerking or snagging. Minimize friction with the roll
holder contact and avoid sharp corners in the media path. Larger, heavier media rolls are
