Scanner Considerations
Document Conditions — The first step in determining the best scanner for a particular application is to clearly identify the documents to be scanned. Characteristics include document size, color, and volume; you should also consider the contrast between printed matter and background, as well as the thickness of the paper.
Duplex or Simplex? — Once you know what types of documents are going to be scanned, check to see if any are double-sided. If there are any double-sided documents, or if you anticipate that you will scan double-sided documents in the future, then it is best to plan for it now and ensure that your scanner is "Duplex". However, if all of your documents are single sided, a Simplex scanner will work just as well as a Duplex scanner.
Flatbed? — Do any of your documents seem like they wouldn't go through an automatic paper feeder? Things like passports, driver's licenses, old and damaged documents, and other similar items require a flatbed scanner. However, if all of your documents are standard paper, then a flatbed will not add any extra functionality.
Paper Handling — An (ADF) allows you to place a stack of documents in the hopper or feeder which then are automatically scanned. An ADF provides for more productive scanning, although some flatbed functionality may be appropriate on documents made from unusually thick material or of small size, such as driver's licenses, or for damaged or delicate documents. Some scanners come with both an ADF and a flatbed..
Scan Speed — Scan volume, document prep (removing staples, paper clips, etc.), loading and unloading of batches, coffee breaks, and paper jams are all factors affecting scanning speed. It's important to analyze how these factors will affect your capture process when choosing scanners and determining how to distribute your scanning load. One higher-speed scanner with distributed indexing makes sense for some environments, where other environments with the same scan volume are served better with several lower-speed scanners offering greater redundancy.
Scan Resolution (dpi) — You do not necessarily need a scanner with high resolution, such as 600dpi. Although there may exceptions, the majority of business documents are scanned black and white at 200-300 dpi. Your ImageNow Implementation Consultant can configure CaptureNow to control your scanner for various levels of scan resolution, color, and other factors to accommodate your various document types.
Scanner Hardware Interface — Video or SCSI? CaptureNow supports both USB and SCSI interfaces. The interface you'll use depends on the scanner you chose and your performance requirements.
