It largely depends on the length of the board. You have two rollers in the planer holding the board flat on the table but until the board gets under both rollers there is a chance of snipe. It usually doesn't do it on short boards but longer boards you have gravity causing the board to raise a little off the table. You can help eliminate that by holding up on the board going into the planer and out. If it still snipes you may have other issues. If your planer has rollers on the bottom they may need to be adjusted down.
