When, on the platen,
the contacting point
between a media
edge and the media
edge guard is near a
platen’s vacuum
hole, the printer may
suck the ejected ink
partially between the
media and the
media edge guard.
As a result, vertical
banding may
appear.
Shift the media so that the contacting point between the media edge
and the media edge guard on the platen does not come close to the
vacuum hole.
