The unit boasts a powerful scanning mechanism, and its standard document feeder holds sheets of paper. Automatic document feeder capacity in sheets. Many scanner manufacturers advertise resolutions of 1, dpi or higher, without mentioning that these are interpolated resolutions that use software and hardware algorithms to fill in the blanks between pixels to make image and text outlines appear clearer and sharper. Most workgroup scanners offer optical resolution ranges of to dpi. 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.

Most scanners are built around similar technology, but their features and performance levels often vary.
Select primary job function. The higher you go, the slower the scan.
A workgroup scanner must also come with fpca robust enough to guarantee a mean-time-between-failure rating in the thousands or hundreds of thousands of hours.
Universal Serial Bus connectors are popular industrywide, but SCSI-2, along with an occasional RSC video connection, will continue to hold sway among workgroup scanners for some time to come. At the other end of the scale, Eastman Kodak Co.

If output speed is your first concern, a monochrome scanner is fine for most workgroup requirements. Feeder time Epson America Inc.
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.
Most are flatbed scanners that have scanning heads sealed in a glass compartment. It’s useful to have both in a document scanner, but OCR software is essential in a workgroup scanner. It should come as no surprise that, given the relatively high prices, there are only a few genuine workgroup scanners available from less than a dozen manufacturers.
You need to hunt them down from value-added suppliers or on manufacturers’ Web sites. OCR software, it is not a question of one or the other but of both. Thus, dpi results in very fast scans, while moving up to or dpi produces slower scans but sharper images. Scanners with automatic document feeders can handle documents from small 3-by-5 cards to by tabloid pages in various paper textures.
Check out scanners designed for a workgroup’s no-frills imaging needs By J. Low-cost sheetfed scanners use a series of rollers to move the paper past the imaging elements, just as fax machines do.
Miles of Pahoa, Hawaii, writes about communications and computers. 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. Most scanning projects require resolutions lower than dots per inch.
Preliminary Testing of Ricoh IS450 (HS2P)
Automatic document feeder capacity in sheets. These units are optimized for scanning black-and-white text pages clearly at fast scanparner, not the fine line and color details produced by image scanners.
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.
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. 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. OCR software bundled with a document scanner turns an image file into an editable text file via its OCR capability.
Monochrome scanners are fine for most workgroup uses. Maximum resolution in dots per inch. Color scanning requires many more ffpa than grayscale scanning, slows down the processing and takes up much more disk space per file than monochrome scanning.
The ppm throughput of these color simplex units is attainable only when scanning text pages at dpi.
The unit boasts a powerful scanning mechanism, and its standard document feeder holds sheets of paper. Maximum paper size in inches. A good MTBF rating backed up with a warranty is one of your best insurance policies 15cc Murphy’s Law, which, for scanners, dictates that a unit will fail at 4: 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.
Fifty- and page document feeders are common; more expensive scanners often hold more, but Canon’s DR and DRC win the prize in this category with capacities of pages each.
