Printing Envelopes on Konica Minolta Digital Press, Update on new Paper Cutter

Testing out the ability of the toner based digital press to print envelopes. I like offset and inkjet, but all I have is toner. I'd be interested to see how other digital presses like the Xerox, Canon and Ricoh do with envelopes. I was impressed, the c3070 only jammed once and it was my fault, I loaded too many envelopes in the feeder. The C3070 was printing at about 3600 envelopes and hour and the C1060 will do 1800 an hour.
I am very impressed with the efficiency of a programmable paper cutter. Will take a bit of practice, and I keep reaching for buttons at the wrong place, but I will learn. Thanks for watching!
