Summary: i borrowed the scanner from a friend before purchasing one myself. as of june 10, 2014, there are no drivers for windows 8 or 8.1. you can, however, use windows 7 drivers. i don't know how the software works since after i installed the drivers, i used acrobat pro 10.1.10. it scanned five pages, double-sided, in 15 seconds. single-sided will take the same amount of time. i liked how it doesn't have to re-feed to scan the other side.
Summary: THE PROBLEM Apparently, this is a known problem that I found out about after having the scanner for a short period of time. You won't know about the problem until you get the error message: "No page in scanner, add page to the scanner?" You can try anything you want, the issue is that a single sheet of paper doesn't WEIGH enough to trigger the scanner. Therefore, you cannot scan a single sheet of paper. THE SOLUTION The solution? Also online.
Summary: Sheet feed works about 5% of the time. Multiple sheets in the input work about 1% of the time. I like the software; but to get sheets to feed is immensely difficult. Will it get any easier? Sheet seems to need to be pushed into the feeder; or the feeder front door must be opened allowing the feed sheet to drop about 1/4 inch or maybe 3/8 into the scanner. I have been able to make very good quality scans but only with great determination.
Summary: I have several DR-2010C and DR2030C. This machine is compatible and like the other Canons of this style, good workhorses for a medical practice that uses them a lot. I started a number of years ago with $3000 Canons (that look a lot like this) but found this. 21 scanners later, I am still pleased. What's good: - works well with network or individual (best) - high speed - single sheet or several pages at a time.
