How to Use Media Edge Protectors

Introduction
Some media tend to have dust and fiber that clings to the edge of the media roll. When released
near the RMO (Roll Media Option) unit platen, these particles can find their way into the printhead
nozzles and cause dropouts that reduce image quality and produce banding.
When to do
When you use roll media that has fibers on the edge of the roll, use the media edge protectors to
stop this material from entering the active print area where the carriage moves across the platen.
The edge protectors are disposable and are intended to extend the time between printhead
cleanings when fibrous media is used.
NOTE
If you use media that is known to have to have "fuzzy" edges you can sometimes minimize the
problem by cutting or burning the debris off.
Required tools
A package of edge detectors is included in the Accessory kit that ships with the RMO unit. If you
run out, you can purchase it as a consumable item (see you local sales representative).
Procedure
NOTE
There are both left and right edge protectors and they are both labeled (a left protector has the
height adjustor, the arc and the indent on the right side, while the right protector is reversed).
1. Bend the bottom edge of the protector along the first crease (located above the label with the part
number) to approx 90 degrees.
2.
Bend the other two creases slightly so that they have a V shape when viewed, as illustrated in the
side view figure below.

3.
Bend the height adjustor (small triangle in the top corner of the edge protector) slightly and then
straighten it again. This results in a slight bend (no more than a media thickness), that allows the
media edge to move more freely under the protector.
