Scanners are environmentally friendly as they store documents in digital copies that can be shared through emails.

Scanners have the ability to produce higher quality images, photos graphics and also designs as opposed to fax machines.Having a scanner in your office or home has a number of benefits. Scanners that have high quality resolution are generally slow in scanning as compared to scanners with low quality resolution. This is not the case with flatbed scanners. Sheetfed scanners can accommodate any size of document. This means the size of the document that a scanner can comfortably accommodate. True colors can only be captured when the scanner has a higher dynamic range. This particular feature of a scanner bases on the range of colors the scanner is able to capture. Scanners with low bit-depth produce low quality black and white scans. It is also the one that determines the colors a scan produces. Bit-depthīit-depth refers to the number of bits that the scanner is able to pick up from the pixels of the image when scanned. The higher the resolution that a scanner has the more detailed image it is able to produce.

Scanner resolution is measured in Dots Per Inch (DPI) or Pixels Per Inch (PPI). This refers to the quality of image the scanner is able to produce based on the number of pixels it can sample. The three types of sensors used in scanners include: Photomultiplier tubes, Contact Image Sensor and Charge Coupled Device. Image sensor works to determine the image quality. The scanner sensor has the ability to convert the light reflected off of the image the image that has been scanned into a digital image. The following are the important features of a scanner that one should look at before purchasing one. Before settling for a given scanner, a potential buyer should carry out an investigation on the types, features, connecting and what models of scanners are considered most popular.
