The media guide stop position may need further adjustment if, after printing or after using the
button to advance several labels:
the media does not track down the center (moves from side to side), or
the sides of the media (liner, tag, paper, etc.) are frayed or damaged when exiting the printer
If additional adjustment does not correct the problem, route the media over the two roll-holding pins on the media guide.
You can also provide additional support for thin media by placing an empty roll core—of the same width as the fanfold media stack—between the roll holders.
