The Enhanced Capabilities Port is the most capable flavour of parallel port. This scanner offers both a flatbed scan and a built-in 25 pages automatic document feeder ADF. So why should you spend the extra? It allows printers and other peripherals that support the standard to send information back to the computer while the computer’s sending data avisio them.

The paper tray also helps to protect the unit from dust. The Enhanced Parallel Port is faster than the old-fashioned one-way ports, which managed only 40 to 50 kilobyte per second transfer speeds and could only send data to peripherals, not receive. Adjusting the “gamma” of an image or of an image acquisition device gives you a way of brightening or 620c without losing as much detail as a straight brightness adjustment.

This “colour gamut” increase is invisible to the naked eye, but it means the scanner can use only a portion of the colours it detects and still maintain full detail.

If ADF option is also checked, only scanners with both features will be found. Of course, I couldn’t do any 3D object scans, including the usual shiny-coin test, with the C, and it’s this that represents a sheetfed scanner’s major disadvantage – if you want to scan solid objects, or out of magazines or books, a sheetfed scanner’s no use to you at all.


A Duplex Scanner Suited for Document and Cards Thanks to the advanced straight paper path and image processing technology, mixed batches of documents with varies sizes and weights can be scanned, appropriately cropped, deskewed, and ready to use.

Testing In operation, the C hums and clicks as it feeds the paper, which was slightly annoying. A preview scan takes 12 seconds. Nobody’s going to be doing high art scans on the C, and cleaner whites may help OCR accuracy a bit.

Equipped with new and improved rollers, it can take virtually any A8 to A3 size mixed documents you throw at it. Most cheap colour scanners are 24 bit; they digitise each of the red, green and blue aivsion with eight bit resolution, making a total of 24 bits per output pixel.

The only annoying thing about OCR scanning was that the standard TWAIN driver popped up and had to be manually set to dpi black and white before the scan proceeded. Xerox’s elderly TextBridge Classic OCR program is also easy to install and use, though elderly; the text it outputs, provided your original document was clearly printed and pretty straight, is likely to require not too much editing.

Includes 1 Year more T he slim designed AD can be easily carried and can fit on most desks without taking up a lot of space. When used as a flatbed scanner it will scan an A4 8. The smiley face on the left is an 11 by 11 pixel image, blown up to 55 by The C scan, done at dpi, captures significantly more detail than the dpi C version click for the full-size image. But don’t scannet fooled into thinking that the apparently perfect white scan means this scanner’s the equal of far more expensive professional models.

Can’t beat that price!

It’s barely more expensive than the C was when I reviewed it, csanner its image quality is noticeably better, it supports a very high maximum resolution, scanner it takes up barely more space. Deskewing, sharpening, auto-crop, blank page removal, page separation, dynamic thresholding, noise removal, auto colour detection speed drops to 40ppm. It’s superficially similar to the C – a bit longer, a bit taller, but with the same 8. You must have JavaScript enabled in your browser to utilize the functionality of this website.

There’s a passthrough port on the back of the scanner for your printer; the scanner has to be turned on for the printer to work, and you can’t use both simultaneously.
