Scanner is one of the important computer accessories.Modern offices cannot do without scanners.Scanners are the devices that convert text and photos on paper into digital images.There are several brands offering scanners of different types and different qualities.When choosing a scanner learn and analyze about the quality of output, driver, speed and software bundle. With advancing technology and increasing competition, scanners are getting cheaper day by day. Even a moderately priced scanner can have features like 4800-dpi resolution and transparency adapters.
Most of the scanners used in home and offices are inexpensive. To improve the quality of the scanners without increasing costs, manufacturers are working for making these scanners easier to use. Some scanners come with increased number of slides and film negatives. For instance, Epson come with Easy Photo Fix Software. This software help correct the signs of aging in old photos.
To differentiate between different types of scanners, you can compare a few features of these scanners. Optical resolution is among the most important factors. If you want to display photos on Web or print 3-by-5 or 4-by-6 snapshots, a scanner with 100dpi is right resolution. For capturing text using OCR (optical character recognition), 300 dpi is the standard resolution. However, for having larger photo prints or to enlarge smaller images, you should buy a scanner with highest possible resolution. Moreover, these larger images capture a lot of space of the hard disk.
Transparency adapter is a light source that shines through the film. To scan slides and films, you require a transparency adapter held in place with a template. A scanner adapter enables the manufactures to keep the lid thin or place an automatic document feeder. It can either be built into the scanner’s lid or they can separate modules that are placed on the scanner glass.
Automatic document feeder can be helpful for handling high-volume optical character recognition or for scanning extra large pages. ADFs are normally built into scanner’s lid.
Interface is another factor which you can compare. Scanner typically comes with a USB 2.0 interface.Some expensive scanners also offer a FireWire connection.
Color Depth is amount of color data a scanner can identify and save. It is measured in bits per pixel. A 24-bit external color depth is satisfactory for almost all the purposes.
