Does the media have ripples/surface
irregularities or lift up?
If you are using roll media, use a smooth section of the media for
initial feeding. You can also improve this problem by attaching the
NITOFLON
®
tape provided on the platen.
Attach the tape, taking care not to block the vacuum
hole.
For more information, refer to the description on transporting media
on the platen. https://mimaki.com/download/inkjet.html
