6-5 Media Wrinkles or Shrinks, or Feed Is Unstable

A variety of problems can occur if the media
feed is not smooth. This can cause such
problems as poor printing quality, contact
with the media by the print heads, misaligned
positioning, or media jams. Take action as
follows.

Media Wrinkles or Shrinks

Is the media loaded and set up straight and
securely?
Feed is not smooth when the media is not straight or
is tensioned unevenly on the left and right. Reload
the media.
Are the media clamps mounted?
When you're performing printing, be sure to attach
the media clamps.

Media Feed Is Not Straight

Is the media loaded and set up straight and
securely?
Feed is not smooth when the media is not straight or
is tensioned unevenly on the left and right. Reload
the media.

Media Feed Is Not Smooth

Do the media or the shafts strike some other
object?
Make sure the media and the shafts do not touch
anything else. This may affect output, even when
feed appears to be smooth.
Is the media too thick?
Media that is too thick may not only cause unstable
feed, but may scrape the print heads, resulting in
malfunction. Never use such media.
Are the grit rollers dirty?
Check to make sure the grit rollers are free of buildup
of foreign material such as media scraps.
