Media Mounting Considerations
The KR203 printer uses direct thermal media which is chemically treated to react to heat.
The printer has several basic requirements for dispensing the media to the printer from a
roll or fan-fold media which 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. A media guide is a required accessory for printing
(see "Media Guide" on page 34).
• 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. Refer to "Media Input Aperture" on page 32 for clearance
requirements.
• 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 born
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
(see "Large Media Roll Adapter – P1026858" on page 60). 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 produce a distorted print (e.g. compressed
print, short receipts, etc.), motor stalls, and jamming if media dispensing to the
printer if the media transition is not smooth and easy for the printer.
