Summary: Update: OK. It appears that Canon finally got their act together at least a little bit and one can now download new drivers that work with Yosemite and Mavericks. I was able to download here: http://www.usa.canon.com/cusa/support/office/imageformula_scanners/imageformula_dr_c125/imageformula_dr_c125_document_scanner#DriversAndSoftware I upgraded them to three stars.
Summary: Let me start with what I consider the most important point: I HAVE YET TO EXPERIENCE ONE JAM OR MULTIPLE FEED. For years I've been putting off scanning the contents of binders I have collected. They are old. The stacks of binders are 5 feet tall, I'd guess several thousand pages. And the paper was not in good shape. I received the Canon DR-C125 yesterday afternoon and began scanning. It scanned this giant pile of paper with no jams or misfeeds!
Summary: This is the first scanner that I have ever owned. I purchased for my business to help alleviate some of the paperwork that we have to keep around the office. Its easy to use and works great. What else could you ask for?
Summary: I would rate this scanner highly for the simple reason it allowed me to install a Twain driver ONLY and then ran clean and smooth. I would knock off a star because the setup guide didn't say anything about removing a plastic shipping clip that blocked the pick rollers until I figured it out. (The clip was bright orange and it did say remove orange TAPE).
Summary: we have scanned piles and piles of old documents ... allowing us to purge bin after bin of files. it really is amazing how well it works ... a press of a button and page after page flies through this scanner. and it is pretty small with clean lines. we simply store it away in the closet and pull it out whenever we have the need to scan. fast set up. fast operation. easy to use. we love it!
Summary: I use a very expensive scanner at work and this Canon one processes things faster than that one. The only negative I can say is it is a bit cumbersome in it's filing of the scan after it has scanned it. A few extra steps needed to make sure the document ends up where I want it. But all in all I would absolutely recommend it to friends.
Summary: I wanted a scanner that I could feed much larger stacks of paper through, and scan in duplex with the click of a mouse. I scanned a lot of docs closing out a family estate and I never even once fed this thing a stack of paper that it could not handle. The "U" paper path was really nice as well. Only a when I occasionally scanned some considerably thicker documents did I switch to the straight through paper path, which also worked perfectly.
Summary: At first I had some problems and most of the software is of no value - wish it were better. However, the "Scan Direct" program is easy and simple to use and this will serve most of my purposes. The machine is fast, easy to file after scanning and I really like the 'paper catcher' - though I usually grab them as they come through. All in all I love the machine and would recommend it. Just hope Canon offers some updated and easier software for more advanced use.
Summary: I use this scanner daily. Call me old school, but I was amazed by the speed of scanning (both sides) and the amount of pages I can scan at one time. I would have given it 5 stars if the software they provided offered a scanning option of black and white.
