7-5 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, media jams, or poor take-up. 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.
Was loaded media allowed to stand for some
time?
Media may shrink or wrinkle if it is heated for an ex-
tended time. When printing ends, switch off the sub
power or remove the media.
Are the media clamps mounted?
When you're performing printing, be sure to attach
the media clamps.
Was the media loaded while the heating
devices were hot?
Loading media after the heating devices have warmed
up causes the temperature of the media to rise sud-
denly, which may cause the media to shrink or wrinkle
during printing. Before loading media, switch off the
sub power and allow the devices to cool.
Is the temperature of heating devices too
high?
Set the temperature to suitable values for the type
of media.

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.
