I bought a used large capacity paper feeder for my hp Laserjet 4

The paper falls about 1/2" short of hitting the first feed roller
inside the printer. I've cleaned all the rollers in the large
capacity feeder and it's made absolutely no difference. The pickup
roller looks good (better than the one for the regular paper try which
never jams). I've tried new paper, tried it half full and completely
full. It still almost always jams. Anyone have any ideas?

Andy,

Get yourself a can of WD40, and a paper towel. Spray some
WD40 onto the towel to form a wet spot. Rub the wet spot
all over the pickup roller until it is completely shiny.

Turn on your printer and it will feed perfectly for the
next few years.

Hey, Chuck, thanks for the great tip! I have been buying Moe's Magic
Printer Roller Reconditioner and it can't be healthy stuff to inhale...
some kind of rubber solvent I guess. BTW, I highly recommend Moe's
fixyourownprinter.com to the OP and anyone else. He is an extremely
knowledgeable and helpful guy and his site has a wealth of information.
