No, I am sorry but that is not any help. I already understood all that. I am loading ordinary business Com-10 envelopes in Tray 1 exactly as specified. I am printing from Microsoft Access and I have properly set the paper type and printer properties to Com-10.
The printer churns and fails to pick up the top envelope of the stack. I think it gave some sort of message ("jam in tray 1", I think).
In various places the HP documentation has said to load the envelope manually. How do you do that?
Why won't it pick up the envelope from the tray?
