I have an HP officejet V40 purchased in 2001. I have attempted to print envelopes as I did with my very old hp laserjet, and I get the address and return address in the wrong places. I tried again and now have a paper jam. The diagram to resolve this problem that was shown on my computer does not match my printer. It has only a tiny "door" about 3"x 5" on the top side thru which the paper jam cannot be reached even with needle-nosed pliers. Actually, only about 1/2 inch is showing. I tried to open this "box" from every angle, even turned it upside down to find an opening where I can release the paper jam to no avail. There aren't any screws to open anything, and prying doesn't help. I received this printer/fax/scanner from a good friend when he bought a new computer that didn't fit. I have no manual which I would like to have to prevent this kind of disaster - which it is to me!
