Here are a couple of articles on loading and printing envelopes. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-821-2797.

Our agency has 3 of these type of printers and whenever we try to print envelopes, it keeps jamming. I even tried using envelopes with less thickness and it still happens. Any suggestions on how to correct this?
