5-4 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
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.
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 and
remove the media.
Was the media loaded while the print heater was hot?
Loading media after the print heater has warmed up causes
the temperature of the media to rise suddenly, which may
cause the media to shrink or wrinkle during printing. Be-
fore loading media, switch off the sub power and allow the
platen to cool.
Is the temperature of the print heater or dryer too high?
Set the temperature to suitable values for the type of media.

The Media 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 object?
Make sure the media and the shafts do not touch anything
else. This may affect printing, 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.
