I'm having an interesting problem. On several of my pages, the majority of the pieces will cut out just fine. However, as it gets closer to the end of the sheet that's not being fed in, it seems as though the knife will travel a little too far. So, far large pieces, the end that's being fed into the cutter will be ok, but the other end will have an extra small bit of paper left on it. Is this normal? I could understand it if the whole piece was slightly off, but not that one end.
