I found on some jointer/planers that this problem, is the way its designed. you can adjust the two feeds close but not close enough. what your supposed to do is push the wood thru one side with pressure on top and side(right hand), then when it touches blade slowly but steadily switch pressure part on the outfeed side. when you think anout it you are cutting an L shaped notch(until the end) so you dont want the side to be exactly parallel. table top jointers are tricky to use.
