The ultra-portable Canon CanoScan N670U offers one-touch capture, fast performance, and excellent image quality for its competitive price. There's no difference between the two models under the hood, but the pricier version has a sleek metallic lid instead of the N670U's dark blue one.
Canon has updated its ultra-portable CanoScan N650U with the N670U, adding useful new features and improving performance. The N670U also offers above-average image quality for its class and comes with a useful software package. Its competitive price should make it even more appealing to home, student, and small-business users. However, if you care more about beauty than bargains, take a look at the pricier CanoScan N676U--it's the same scanner with a snazzier lid.
Roughly the size and weight of an extra-wide laptop, this 600dpi scanner is powered directly from its USB connection, so you can hit the road without toting a bulky power brick. Velcro tabs keep the flatbed's cover snugly in place, and the scanner head locks for transport with a slide switch, letting you just tuck it under your arm and go.
If you can't clear a 25.7x38.4-cm desktop space for the 3.6-cm-thick scanner, you can set it on its side in a snap-on stand to scan in a vertical position. Upright, the scanner leans at a slight angle to let you rest single sheets on the scan bed. In practice, vertical scanning doesn't save very much space, since you still need to clear roughly 20.3 cm of desktop to open the scanner lid. You'll want to scan books and thick documents with the scanner lying flat to take advantage of the lid's clever hinge, which opens a full two and half centimeters to accommodate bulky originals.

7We tested the N670U's fraternal twin, the N676U, and found it a snap to install. Link the scanner to your computer with the included USB cable, and Windows finds it automatically. Spend a few minutes installing the bundled OCR, photo editing, and album software, and you're all set to scan and organize both documents and images. The photo-album program can even write to a CD-R disc. The scanner isn't built for high volume or film scanning, however, and there are no transparency adapter or automatic document feeder add-ons for it.
If you eschew the three front-panel single-touch buttons, the ScanGear Toolbox's user-configurable icons can direct a scan to your printer, email, a file, your choice of image editors, or the OCR software. A full-featured ScanGear Twain interface offers complete control over scans in both simple and advanced modes from within image editors such as Photoshop or PhotoStudio. The multi-photo mode, which captures and crops multiple images from a single scan, is particularly useful.
In our lab tests of the N676U, which is identical to the N670U under the lid, the scanner turned in above-average results for its class when it came to image quality. Skin tones looked natural, and colour balance was good. The scanner has an outstanding ability to capture the brightest whites and deepest blacks. However, it fell down on tonal separation in shadow areas, failing to capture the distinction between several shades of dark grey. We also noted slight misregistration and a small amount of colour noise. Still, our images looked smooth and well balanced on the whole. The scanner is an ace at sharp text capture, outpacing many of its peers. It also stays ahead of the pack in terms of scan speed, with both colour and monochrome originals.
True portability, useful features, and good performance make the CanoScan N670U an attractive package for those with basic scanning needs, limited desk space, and a desire to use a scanner with multiple computers.
