In today's technology-driven era, there is a need to store documents electronically. Now, there is no longer any need to save a large number of documents in files and folders as scanners have revolutionized the way you can store and retrieve documents. Computer scanners can convert sketches, drawings, images and text done on paper in a digital form. With the introduction of advanced scanning equipment, the scanning process and document management has become easier.
The types of scanners available include sheet-fed scanners, film scanners, handheld scanners, flatbed scanners and multifunction scanners. Flatbed scanners are preferred by most users as they are easy to use, offer simple functions and are commonly found in offices. Handheld scanners are used to scan manually. Photo scanners or film scanners as the name suggests scan pictures, but other scanners can also allow you to scan photos. Portable scanners are very handy and can fit in your pocket easily. Sheet-fed scanners require you to feed the pages you need to scan one by one. Other popular scanners offer multiple function, including serving as a printer and a fax machine.
In offices, scanners are quite useful as there is a requirement of a softcopy of many important documents. The scanner can print handwriting, scan images, print text and also scan an object, thereby converting it into digital images. One can email their photographs to their friends with the help of a scanner. The scanners also have image editing software that can be used once the image is copied in the computer.
Scanners are extremely useful for businesses as well as at home. Ease-of-use is one of the most distinct advantages of modern scanners. High speed, portability and digitization of documents without harming the original document are some of the other advantages. Since the scanners are outfitted with software, the documents and pictures are printed in the same manner and also can be saved in various formats.
When selecting a scanner, it is essential to check the features and select one that has accurate DPI level, color depth and scan area. All these features are essential for the best performance. DPI level has to be perfect for having an exact copy of the documents and pictures. For those who need realistic results in the scanned images, scanners with high-color depth must be selected. With a greater color depth, the pictures or documents can be given a livelier and more realistic look. The size of the scan area required must also be a consideration so that it matches your needs.
It is necessary to consider the way in which the scanner will be connected to the computer. The scanners available in the market make use of the USB port. The other modes of connection that can be used have a small computer system interface, fire wire and parallel.
Some models also power off of the USB connection, allowing you to take the scanner along with your laptop computer without the need of an extra power cable.
