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 and are simplex models, meaning they provide single-sided scanning. A Scsl includes a lens, light source and chip set, along with an analog-to-digital converter for translating the data gathered into digital information.
Most workgroup scanners offer optical resolution ranges of to dpi. Scanners with automatic document feeders can handle documents from small 3-by-5 cards to by tabloid pages in various paper textures.
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.

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. If you scan svsi full-page color image, the process will be slowed to 1 page or less per minute. Most are flatbed scanners that have scanning heads sealed in a glass compartment. Feeder time Epson America Inc. 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.
An automatic document feeder, preferably built-in, allows smooth transfer of the original to the body of the scanner, where scwnpartner data on the paper can be read by the scanning heads and passed on to the host computer.
The ppm throughput of these color simplex units is attainable only when scanning text pages at dpi. Select primary job function. Maximum paper size in inches. This buying guide features scanners that meet the document processing requirements of typical workgroups and small departments.
Scanners work faster at lower resolutions. What is your primary job function?
Fujitsu ScanPartner 15C Specifications
These units are optimized for scanning black-and-white text pages clearly scanpartnerr fast speeds, not the fine line and color details produced by image scanners. 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.
If output speed is your first concern, a monochrome scanner is fine for most workgroup requirements. You can use one to scan sequential pages of different sizes, but the risk of jamming and other mechanical failure is high. The Email address field sxanpartner required.

Actual optical resolution is a function of a scanner’s charge-coupled device or contact image sensor. The higher you go, the slower the scan. Sign up for our newsletter. Miles of Pahoa, Hawaii, writes about communications and computers.
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. Scabpartner sheetfed scanners use a series of rollers to move the paper past the imaging elements, just as fax machines do.
OCR software, it is not a question of one or the other but of both. Monochrome scanners are fine for most workgroup uses. Universal Serial Bus connectors are popular industrywide, but SCSI-2, along with an occasional Xcsi video connection, will continue to hold sway among workgroup scanners for some time to come. But this shouldn’t deter you if you’re looking for quality and performance. You need to hunt them down from value-added suppliers or on manufacturers’ Web sites.
The units listed provide at least ppm or faster text output, with optical resolutions of to dots per inch. 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. Depending on simplex or duplex operating modes and paper requirements’typically 8.
