• 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 (see "Roll Support – P1014124" on page 68). 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 – P1014123" on page 75
and the "Universal Roll Holder – P1014125" on page 70 side views to illustrate roll size
and contact with a media guide.
Designing for Fan-Fold Media
Fan-fold media creates unique challenges. It has square edges that can get caught and
the stack can fall into other components and cabling.
Make a tray to hold the fan-fold media unless it is being pulled straight up. Always test and
observe with the actual media. Fan-fold media can un-fold erratically and act differently at
the beginning and end of the stack.
Design a tray a little higher than the height of a full stack of media. Fan-fold media tray
should keep the media stacked and never allow the media to be pulled into the kiosk.
When using a media guide, the guide should ideally be twice the distance of the length of
the media stack away from the media guide and aligned to the center of the stack. This
allows the media to completely unfold and minimizes the chances of having it bind in other
components or printing multiple receipt or tickets.
