3100cn printing on vellum/translucent paper

I am trying to print colored text on a sheet of "vellum", plastic really, or translucent paper (43lbs.), letter-sized.  The only paper setting using the Manual Paper Feed (MPF) that will recognize and try to print is "Transparency".  When I chose that option, the paper feeds, but then stops, and I receive an error message to open the back of the printer and remove the sheet.  I have tried all other paper (plain 1, plain 2, cover 1, cover 2, label, coated 1, coated 2, etc.), and in all cases, the response is "Load XXX".  I have printed on this very brand and color of translucent paper in the past with color laser printers without problem, so I believe it can be done, but I have not had any success at all trying to print on my 3100cn with this paper or its lighter version.  Is it the paper?  Is it my printer?  I was under the impression that the Dell 3100cn could print on "vellum" or translucent paper.  Am I wrong?

If you know how to configure the Dell 3100cn to print on this type of paper, please reply as soon as possible.  Any and all advice is sincerely appreciated!
