Basic Media Mounting Considerations
The KR403 printer has a few basic requirements for dispensing the media to the printer
from a roll or fan-fold media. The KR403 printer exclusively uses direct thermal media and
it is chemically treated to react to heat. Some of these basic considerations include:
• Align Printer with Media – The center line of the media roll or fan-fold stack should
align with the center of the printer to provide the best image quality and keep the
media un-damaged. Always use a media guide when printing!
• Media Only Contacts Media Mounting and Printer in Kiosk – The media should not
touch cables, other kiosk components, or surfaces other than media guides or the fan-
fold media tray.
• Do Not Blow Air on Media – Air should be pulled out of the media area of the kiosk to
keep dust (shortens printhead life and affects print quality), aerosol bourn chemicals
(such as cleaning solutions like ammonia) and exhaust heat from other kiosk
components and power supplies.
• Direct Sunlight, Incandescent or Infrared Lighting or Heat Sources – These light
sources can come from kiosk vents and other kiosk components. Incandescent light
bulbs and heat sinks are examples of heat sources that shouldn’t be near the printer,
media or media storage areas.
• Media Dispensing Must Be Smooth and Easy – Roll media must be able to turn
with little or no drag, and allow the printer to smoothly pull media without jerking and
stopping. Larger, heavier media rolls are more susceptible to these issues. Minimize
roll to roll holder contact and avoid sharp contact surfaces. Fan-fold media must have
sufficient room to unfold and not bind on media guide surfaces or at the perforations or
sides. The printer can get distorted print (e.g. compressed print, short receipts, etc.),
motor stalls, and jamming if media dispensing to the printer is not smooth and easy for
the printer.
