The Media Becomes Soiled or Damaged When Printed

Do the print heads contact the media?
The print-head height may be too low. Also, if the media is not loaded and set up correctly, it may wrinkle or
come loose and strike the print heads.
 P. 122, "Adjusting the Print-Head Height to Match Media Thickness"
 P. 155, "Media Feed is Not Smooth"
Are the print heads dirty?
The following may cause ink to drip on the media during printing.
 Buildup of fibrous dust (lint) around the print heads.
 Ink transferred to the print heads due to rubbing against the media.
If this happens, perform the manual cleaning. We recommend carrying out periodic cleaning of the print heads.
 P. 97, "Maintenance that Should Be Performed More Than Once a Month"
 Too Low Humidity.
Use this machine in the environment of 35 to 80 %RH (non condensation).
Are the pinch rollers, media clamps, grit rollers, or the rubber covers on the front of the
machine or on the front cover 2 dirty?
Periodically clean them.
 P. 93, "Cleaning"
Are the pinch rollers positioned correctly on top of the rigid media?
Adjust the position of the media so that the pinch rollers are completely on top of the media. If the pinch rollers
are not completely on top of the media, the media will still pass through the machine, however, depending
on the characteristics of the media, an imprint from the pinch rollers may be left behind or the media may
be dented.
