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 roll media sagging?
Sagging of the roll can cause wrinkling or warping. When
loading media, install the reinforcement pipe. Also, when
storing media, place it so that it will not sag under its own
weight.

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

Do the media or the media flanges 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.
