It’s useful to have both in a document scanner, but OCR software is essential in a workgroup scanner.

Scanners work faster at lower resolutions. The SCSI-2 interfaces coming with virtually all the scanners listed are necessary to handle high-bandwidth graphics and document management tasks faster than the parallel interfaces used with inexpensive personal or small-office scanners.

Actual optical resolution is a function of a scanner’s charge-coupled device or contact image sensor. A CCD includes a lens, light source and chip set, along with an analog-to-digital converter for translating the data gathered into digital information. The unit boasts a powerful scanning mechanism, and its standard document feeder holds sheets of paper.

If output speed is your first concern, a monochrome scanner is fine for most workgroup requirements. Depending on simplex or duplex operating modes and paper requirements’typically 8.


Feeder time Epson America Inc. A workgroup scanner must also come with components robust enough to guarantee a mean-time-between-failure rating in the thousands or hundreds of thousands of hours.

In many cases, using a low-cost desktop PC color scanner or a dedicated image or photo scanner may take up the slack when color is required.

The ppm throughput of these color simplex units is attainable only when scanning text pages at dpi. Miles of Pahoa, Hawaii, writes about communications and computers. Scanners with automatic document feeders can handle documents from small 3-by-5 cards to by tabloid pages in various paper textures. Low-cost sheetfed scanners use a series of rollers to move the paper past the imaging elements, just as fax machines do.

These units are optimized for scanning black-and-white text pages clearly at fast speeds, not the fine line and color details produced by image scanners. Thus, dpi results in very fast scans, while moving up to or dpi produces slower scans but sharper images.

A good MTBF rating backed up with a warranty is one of your best insurance policies against Murphy’s Law, which, for scanners, dictates that a unit will fail at 4: Most workgroup scanners offer optical resolution ranges of to dpi. Others, such as Hewlett-Packard Co. As for image editing vs.
