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.

An automatic document fcps, preferably built-in, allows smooth transfer of the original to the body of the scanner, where the data on the paper can be read by the scanning heads and passed on to the host computer. Actual optical resolution is a function of a scanner’s charge-coupled device or contact image sensor.
OCR software bundled with a document scanner turns an image file into an editable text file via its OCR capability. Color scanning requires many more pixels than grayscale scanning, slows down the processing and takes up much more disk space per file than monochrome scanning.
The prices of the 38 workgroup scanners listed reflect their features and capabilities. If you scan a full-page color image, the process will be slowed to 1 page or less per minute.

Most scanners are built around similar technology, but their features and performance levels often vary. Most workgroup scanners offer optical resolution ranges of to dpi. Others, such as Hewlett-Packard Co.
Automatic document feeder capacity in sxanpartner. At the other end of the scale, Eastman Kodak Co. Virtually all workgroup scanners come with a built-in or optional automatic document feeder and specialized software for cropping or redesigning photos or graphics, and optical character recognition software for text editing.
Thus, dpi results in very fast scans, while moving up to or dpi produces slower scans but sharper images. Monochrome scanners are fine for most workgroup uses. Miles of Pahoa, Hawaii, writes about communications and computers. Many users need to be able to move hard copy, photos or graphics onto a PC or workstation hard drive so it can be stored, edited or otherwise manipulated for later use.
OCR software, it is not a question of one or the other but of both. As for image editing vs. This buying guide features scanners that meet the document processing requirements of typical workgroups and small departments. 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.

Although many vendors still make the choice within models, more products such as Canon’s DR and DRC are packaged with user-selectable simplex and duplex modes.
The ppm throughput of these color simplex units is attainable only when scanning text pages at dpi. What is your primary job function? The higher you go, the slower the scan. 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. Most scanning projects require resolutions lower than dots per inch. You can use one to scan sequential pages of different sizes, but the risk of jamming and other mechanical failure is high.
Easy to set up and use with a PC or Macintosh, they operate at maximum speeds of only several pages per minute and are too lightweight for workgroup use, except in a pinch.

Scanparhner come with a sheet document feeder. 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: It’s useful to have both in a document scanner, but OCR software is essential in a workgroup scanner.
