Canon DR-4010C review

Price when reviewed

No other manufacturer offers a wider range of business document scanners than Canon, and its DR-4010C raises the bar in its class for scan speed and paper-handing capabilities. This compact unit offers a remarkable 42ppm scan speed for both mono and colour and can handle media up to 1m in length. It also incorporates a straight-through paper path for heavy media weighing up to 480gsm.

Canon DR-4010C review

The input tray, which handles 100 sheets, can be folded into the main unit when not in use, and the scanner and paper roller mechanisms are all housed in a single unit. The DR-4010C has the same three-line CMOS sensor used in Canon’s higher-end models, which aims to improve quality by simultaneously reading each RGB colour, and has a shading mechanism to protect the sensor from paper dust.

For testing, we loaded the software and drivers on a Supermicro 3.2GHz Pentium D workstation running Windows XP SP2 and then connected the scanner using the supplied USB cable. It was identified without any problems. Canon bundles the ISIS/TWAIN-compatible CapturePerfect 3 software, which provides a big bundle of tools including options for batch scanning directly to a file, printer or email. A presentation option scans the loaded documents and presents a full-screen window with the first page displayed. The Backspace and Enter keys are used to move through the pages, and a right-click menu offers options to zoom in and out, rotate the current page and display thumbnails to one side.

With batch scanning to a file, you can choose PDF, TIFF, JPEG or BMP formats, and our testing matched Canon’s claimed speeds. With either 300dpi or 600dpi mono modes selected, scanning 42 pages of bank statements to a PDF took precisely one minute. At 600dpi, the PDF file size was approximately twice that of the 300dpi version. When you finish, you can either save each page as a separate file or save them all into a single file. Scanning directly to mail is simple enough, as you just choose this option with the documents loaded. You select PDF, TIFF or BMP formats and the scanner scans each page, creates a file or files and opens your mail client with a new message containing them as attachments.

Output quality is impressive and we could see a distinct improvement with text at 600dpi. CapturePerfect’s text-enhancement modes are a bit hit and miss: although text quality was improved, it scattered an unsightly mess of dots and smears on the image. However, scanning colour photographs at 600dpi with 24-bit colour selected produced remarkably good results, with absolutely no banding evident. The scanner also has an automatic colour-detection mode, which we found worked perfectly, so doing away with the need to separate documents out prior to scanning.

Canon’s latest desktop scanner is undoubtedly a speed merchant and the bundled software offers a lot of very useful features. Output quality is good for both mono and colour and, although the price is high, any businesses serious about scanning physical documents will soon recoup the costs.
