Solutions
Remove the imaging units one at a time, and check
for damage. If it is damaged, replace it.
Select the proper setting in the printer driver to switch
from transparencies to plain paper.
Adjust the humidity for media storage. Remove the
moist media and replace it with new, dry media.
Load the correct media in the printer.
Remove the media from the tray and check for static
electricity. Fan plain paper or other media (but not
transparencies), and replace it in the tray.
Remove the media, tap it to straighten it out, return it
into the tray, and realign the media guides.
