If any one could help me out with my printing problem, I would really appreciate it. From the quality of the posts, I can see that there are some smart people here, and I hope my question isn't stupid. If you have a question, ask someone smarter than you, right? I am trying to print colored text on a sheet of "vellum", plastic really, or translucent paper (43lbs.), letter-sized, on a Dell 3100cn color laser printer. 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 and 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!
