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. Image editing software often comes with filters to apply special effects and helps you manipulate the colors and tones of images to improve the display. New from GCN Computing steps closer to the network’s edge. Most workgroup scanners offer optical resolution ranges of to dpi. Most are flatbed scanners that have scanning heads sealed in a glass compartment. The units listed provide at least ppm or faster text output, with optical resolutions of to dots per inch. The unit boasts a powerful scanning mechanism, and its standard document feeder holds sheets of paper.

Fifty- and page document feeders are common; more expensive scanners often hold more, but Canon’s DR and DRC scanpaartner the prize in this category with capacities of pages each. In workgroups and small departments, forms processing, records management and document imaging are a few of the uses for an in-house scanner.
OCR software, it is not a question of one or the other but of both. Original documents are passed either manually or via an automatic feeder over the top of the glass, with the scanning heads passing beneath to capture the image.

But this shouldn’t deter you if you’re looking for quality and performance. Sign up for our newsletter. 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. What is your primary job function? 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: Thus, dpi results in very fast scans, while moving up to or dpi produces slower scans but sharper images.
Miles of Scsu, Hawaii, writes about communications and computers. Fujitsu’s ScanPartner 15C can scan up to 15 color pages per minute at dpi resolution and can handle paper in sizes up to 8. Maximum paper size in inches.

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 fcpaa used with inexpensive personal or small-office scanners. The unit boasts a powerful scanning mechanism, and its standard document feeder holds sheets of paper. Most scanning projects require resolutions lower than dots per inch.
Automatic document feeder capacity in sheets.
An automatic document feeder, 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 ssi scanning heads and passed on to the host computer. Scanners work faster at lower resolutions. In many cases, using a low-cost scapnartner PC color scanner or a dedicated image or photo scanner may take up the slack when color is required. Most workgroup scanners offer optical resolution ranges of to dpi.
Most scanners are built around similar technology, but their features and performance levels often vary. Image editing software often comes with filters to apply special effects and helps you manipulate the colors and tones of images to improve the display.
Maximum resolution in dots per inch. Most are flatbed scanners that have scanning heads sealed in a glass compartment. 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.

At the other end of the scale, Eastman Kodak Co. 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. Check out scanners designed for a workgroup’s no-frills imaging needs By J.
Select primary job function. The and are simplex models, meaning they provide single-sided scanning. OCR software bundled with a document scanner turns an image file into an editable text file via its OCR capability. The ppm throughput of these color simplex units is attainable only when scanning text pages at dpi.
