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, mis-
aligned positioning, media jams, or poor take-up. Take ac-
tion 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
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 extended
time. When printing ends, switch off the sub power or re-
move 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 suddenly, which
may cause the media to shrink or wrinkle during printing.
Before loading media, switch off the sub power and allow
them to cool.
Is the temperature of heating device 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
tensioned unevenly on the left and right. Reload the media.

Media Feed Is Not Smooth

Does the media or the shafts strike some other ob-
ject?
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.
