Try to get new drivers from hp.com

There is a recall fix on this printer if it has specific feed problems like pulling in multiple sheets etc. Might be related. You can contact HP and they'll send you a DIY fix kit to replace the rubber that pulls the sheet in and onto the rollers.

See that top on which to place paper faxing is a green button should be positioned (to the right or left) in position with several sheets drawn as an indicator. I guess yours is positioned on a single paper which means it does not separate anything you ask.
Good luck to configuration

This is most likely a paper problem, the paper is basically sticking to the next sheet, Ensure the paper is stored in a cool dry place helps, dont load the paper with more than what you need for a couple of days and when loading the paper flick the pages to allow air between the pages
If this dosnt work try a different brand of paper

check the feeed rollers ateh seperation roller the one that seperates the pages is worn.. it has proberly worn the tread and if its sn=mooth or worn it wont stop multi feed

Put paper in a gallon sized storage bag; turned fan onto printer. (problem appears to have been the humidity level)

Try fanning your paper several times. Take that nice neat pile of paper in your hands and wiggle it so that your thumb fans through the edge of the whole stack. Do this on both edges so that the stack of paper is slightly less perfect. You can also gently fold the whole stack slightly in both directions. Do this every time you add fresh paper. It should only take a few seconds.

I'm having a similiar problem. Can't consistantly feed one sheet at time. If i load several sheets it pulls all through, etc
