I have only had this scanner running for about 6 days, but I'm very pleased with it so far.
I'm not using it for a business, but to scan about 32 linear feet of material that I have acquired from various archives over the years in order to downsize, and get rid of 4 or more filing cabinets.
The sheet feeder is a boon, and has coped well even with different sizes of paper in the same batch. It has also scanned very light paper, from the Sunday Times colour supplement, without jamming. Scanning to image pdf is at about 20 pages per minute at 300dpi, and it scans double-sided pages in a single pass (making 40 images per minute possible).
I found loading the software a bit tricky, but may have auto-run disabled.
The accuracy of the 'pure' pdf in OCR depends on the quality of the original. It can be virtually 100 % accurate.
I'm glad I bought this model.
