Using the Canon ImageFORMULA DR-C125 is very straightforward. You load one or more sheets into the feed hopper and start a scan by selecting it in software, via Twain or application scanner support, or by pressing the one-touch button on the scanner’s front panel.
Canon quotes the scan speed at 15ppm or 30ipm, if you're scanning a duplex document. The scanner has twin scan heads so only requires a single pass to capture both sides of each page. Our 10 duplex page (20 side) test took 42 seconds, so very close to the claimed speed. A single page at 200ppi, a suitable resolution for archival, took five seconds.
Scanning at 300ppi and applying OCR to a single greyscale page scan took 16s and a 15 x 10cm 24-bit colour photo scan at 600ppi took 14s. All the speed results are very reasonable for a scanner in this price bracket and you should be able to use it on a daily basis at high throughputs, without much waiting.
Scan quality is also good for the tasks the scanner is aimed at. Our black-and-white text page at 200ppi was perfectly readable and for archiving large quantities of paper-based documents would provide more than adequate quality for visual recognition on-screen.
OCR at 300ppi also proved to be very good, with only a couple of recognition queries in technical areas of documents, or when using more obscure fonts. OmniPage is renowned as one of the best OCR tools available and even if you use the OCR engine built into PaperPort, you're still getting good recognition quality.
Colour print scanning produced good quality images at the scanner's top resolution of 600ppi. Our test images were perhaps a little dark by default, but this can be easily tweaked within the supporting software.
Sheetfeed scanners with duplex scan heads don't come cheap, and Canon's ImageFORMULA DR-C125 is no exception, but it does the business and builds in its J-path paperfeed, so providing a very small desktop footprint. Speed and scan quality aren't sacrificed in this design and the software bundle is both comprehensive and well integrated. All in all, it's a well-designed desktop scanner for any office which has a quantity of paper documents needing regular conversion to their electronic equivalents.
