Digital BW, The Print

Has anyone used this paper in either a 2400 or 1800? It is the
thickest paper I've ever seen and jammed my 1800 even when the 1800
was set to 'thick' paper.
 When I compared the thickness to the VFA, the Max appears at  least
50% thicker! I am doubting Crane's quality control as they list the
thickness at 21. (The VFA is 19) The paper is a LOT thicker than the VFA.

 I was afraid to then try it in the 2400.
