Kiosk Design Considerations

Designing Your Own Media Dispensing System

Designing Your Own Media Dispensing System

Properly dispensing the media to the printer is critical to the operation of the printer and

quality print. The media, roll or fan-fold, needs to flow smooth and free with minimal drag or

binding. Ideally it should have a clean and cool location for dispensing and storing media.

Loading or dispensing media to the printer should not have interference or access restrictions

with the kiosk enclosure or internal components.

• The media entering the printer should be aligned to the center of the printer.

• The printer and roll media should be level to prevent drag on the side of the roll and

damage to the receipt edges. This can cause jams and printer stalls in the worst case

conditions.

• The media should never touch or rest on cabling, kiosk walls and components,

exhaust fans (dust and heat), heat sinks, etc.

• The media should be easy to reach and see inside the kiosk. Do not force the operator

to bend or extend their arms too far into the kiosk to load media or service the printer.

• Optional Media Storage — Media stored in the kiosk should have a dark cool area

separate from the rest of the kiosk enclosure that can be closed off from the heat of the

kiosk components, moisture, and cleaning chemical vapors used near the kiosk.

Designing a Roll Support

The design elements needed for a good media roll support are:

• Simple design with no loose parts that can get misplaced, installed incorrectly, or

require special techniques that can, when done incorrectly or carelessly, have the

operator drop the media in the kiosk.

• Minimal drag. Do not use wires, cables or bars as a roll holder - all of these cause the

roll to stop and start and rock back and forth. Narrow radius roll supports case these

behaviors to a lesser extent. Some media vendors use roll cores made of fiberboard

that can have seams. The KR403 Roll Support accessory minimizes the media contact

area (only makes contact with the outside edges) and a large enough radius to smooth

over seams. The larger the roll (more mass), the greater the effect it has on drag.

• Leave plenty of access room to load media when designing the area for your roll

support. Leave additional clearance for the roll swinging on the support and hands

that hold the media to load it.

Designing Media Guides

The media guides need to have a minimum radius of 10 mm. The surface should be smooth

and not touch the edges of the media (causes drag or edge damage). The media should only

touch radius surface and not the edge of the radius for all roll sizes that may be used (full or

nearly empty). See the Wall Mount Roll Holder on page 88 and the Universal Roll Holder

on page 83 side views to illustrate roll size and contact with a media guide.
