Note, this is really tough with plastic feed rollers and no bed rollers.

Speaking of which, that is one thing that the planer
can do too...I have had good luck with flattening slightly
cupped boards by putting the cup down on the planer bed, and
taking a number of light cuts until I have a nice, flat surface.
Then, I can flip it over, and, run it through and take off the
"horns" on the concave side of the cup. Of course, this does
not help with twisted boards, but, I have shooting sticks and
hand planes to deal with that. The trick is to take a light
enough cut that the feed rollers do NOT flatten out the cup,
but, simply pull the wood through the blades. It goes
surprisingly quickly and works well.
