Another thing the 360 does not have is a loop former. It has a tension bar that connects to spring arms on either side. Even pressure all the way across.
If I am not mistaken, it is the same as the 260, a metal tube attached to plastic arms that are attached to a metal axle. If HP no longer ships the plastic loop former, that is a shame because it is necessary for narrow media i.e. 24", 30", 36", 42" and 54".
