Query: Double-feed a big problem

This machine has tremendous trouble with feeding. One third of the time I get a double feed which means that I have to rescan the whole stack. Also, when you scan certain paper sizes (ie my Verizon bills) it crops the sides (where the dollar amounts are) since the bills are of a size that is one of the pre-determined sizes. Of course, I could measure the size of the bill and imput it manually, but that would be a tremendous hassle if I have to measure every paper and imput its size (why not just make the scan area a little bigger (ie letter size). It is not that user friedly and you really lack flexibility by not having a twain driver. The speed is good and the two sided scanning a plus. Resolution is poor and the machine overall seems to be overpriced for its cheap construction.
