What I think you're saying is that bigger/more robust planers will use a roller that has "teeth" to pull the lumber in. These teeth marks are then removed by the cutting action in most cases, UNLESS you're taking a very light cut... in which case you would need to handle those teeth marks via sanding / card scraping etc.
Do I have that about right?
Bob -- Not trying to jump in line, but that is essentially correct. Industrial planers typically come up with serrated steel infeed rollers which can leave impressions when the cut is very slight (like less than a 32nd). So called lunchbox planers usually have rubber infeed rollers that don't have that issue. You can sometimes spec rubber infeed rollers on the larger planers.
