Digital BW, The Print

I've searched previous threads on this topic and have tried all the
tips, like applying slight pressure on the paper edge, curling the
paper slightly, and not applying _too_ much pressure either, for that
matter.

Am using 5x7 paper, tried having just one or sheets in the feeder, up
to a dozen, but no matter what I do the paper just feeds right on
through and I get a 'paper not loaded correctly' message.

I've run out of things to try. May have to get a different model Epson.

PS: In fact, sometimes the paper feeds right through without my
nudging it at all, not even touching the paper. Oh, and I've also
tried the heavyweight paper setting in the print menu.
