Query: Don't get this model if you do a lot of scanning

I am thinking of returning my unit, here is why. The scanner is very slow. My old Canon MP 730 scanned about 3 times faster. I scan a lot of documents to PDF. I called Canon tech support and they were very nice but could not help me improve the scanner speed. The tech support rep did confirm that the MP780 was slower than the older MP 730. Canon really went backwards by having their new model be about 3 times slower than their previous model. I was hoping thr MP 780 would be a better version of the MP 730 but it is not. Someone at Canon made a very poor decision regarding the scanner for the MP 780.
