I am using a Xerox Altalink C8145. I have my envelopes ready to go in Drawer 5 and have progammed the printer and my computer for the envelopes. I am printing our office return address on the envelopes, so I am having to open the flap and turn the envelopes around in order to get it to print from a PDF file. In the beginning, I was able to print 17 envelopes this way. And then the copier started jamming and I haven't been able to get it to stop. I have restarted the printer. Deleted and reentered jobs. Put in fewer envelopes and nothing works. It continues to jam at Area A2. Below is a picture of what it is doing. It isn't clear, in the picture, but the flap appears to be what is causing the jam.
Hello G.Dawson,
When printer envelopes the flap should be closed not open, this could be why its jamming. Please view this article on how to load envelopes.
