Solution
[Symptom A] [Symptom B]
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.
