Thank you Damfino for your reply. Before we purchased the unit we were told and Xantes advertisments stated that it would print on about any stock, canvas, magnetic, etc. One of our big concerns was the price of the unit and only being able to purchase supplies, toner, drums etc, thru Xante, but when we were told it would print on all these other papers, well, it looked like a great fit for our company. We have ran 100# gloss cover, 120# C1S, magnetic 12x18,80# Cover and envelopes. Remember, this is a brand new machine, and neither we or the service tech can get the image to fuse correctly, or the colors to be solid. I am very curious if this machine will actually print on all the stock advertised by Xante. You are 100# correct when you say it will print beautifully on a #10 Reg. Bond envelope. We ran several 1000 thru it and they looked great. I was very impressed. I would like to know if there are other printers having similiar problems with this unit. If I could just run #10 Bond envelopes thru this all day Im sure it would be fine, but in order for it to pay for itself, it has to be more versatile.
