5-5 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.
Is the feed dancer roller level?
If it is not level, the media may become crooked or wrinkle.
Reload the media using the media gauge.
Is media loaded correctly?
Make sure the media is passed through the guide roller and
dancer rollers correctly.
Is the positioning of the loaded media displaced to
the left or right?
Smooth feed is not possible when the positioning of the
loaded media is displaced to the left or right. Reload the
media using the media gauge.
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.
Was the media loaded while the media heating sys-
tem is hot?
Loading media after the media heating system has 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 the media heating system too
high?
Set the temperature to suitable values for the type of media.
p 48 "Settings of the media heating system"
Is the roll media sagging?
Sagging of the roll can cause wrinkling or warping. When
loading media measuring 1,880 mm (74 in.) or more in
width, install the reinforcement pipe. Also, when storing
media, place it so that it will not sag under its own weight.
p 33 "How to Load 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.
Is the feed dancer roller level?
If it is not level, the media may become crooked or wrinkle.
Adjust the position of the balance weights to match the
width of the media.
Is media loaded correctly?
Make sure the media is passed through the guide roller and
dancer rollers correctly.
Is the positioning of the loaded media displaced to
the left or right?
Smooth feed is not possible when the positioning of the
loaded media is displaced to the left or right. Reload the
media using the media gauge.

Media Feed Is Not Smooth

Do the media or the dancer rollers strike some other
object?
Make sure the media and the dancer rollers do not touch
anything else. This may affect printing, even when feed ap-
pears 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.
