A scanner is a device that can scan various documents and images and even objects and then converts them to a digital format and they can be used for a variety of purposes such as scanning photos or digitally archiving documents and letters and they can also be used for optical character recognition, commonly known as OCR. It is defined as a process where scanned text is turned into code that can be read by word processing programs and converted to other formats but when selecting the right scanner the person needs to consider the various types of scanners available and their different uses.
An important thing to note is that there are different kinds of scanners at this website, which include: flatbed scanners, photo scanners, handheld scanners, sheetfed scanners, drum scanners and slide scanners. A known fact is that a Flatbed scanner is the most popular type of desktop scanner and it consists of an optical array that moves up and down a glass plane and they are very useful because they allow the user to scan an array of documents of various sizes and they can even scan small 3D objects and they are an excellent choice for the user that frequently scans documents.
It is important to note that a photo scanner designed to scan pictures precisely and thus its main features include an ability to be able to scan documents at high resolution and in color and for most basic scanners they can scan hard copies of prints but for users that also need to scan negatives they need a special kind of scanner. One of the demerits of photo scanners is that they are more expensive than regular desktop scanners and they often come with special software included in it that the user can use to manipulate the scanned photos.

A known fact is that handheld scanners are small, designed to be portable and may be so small that they can fit in a laptop bag. It is worth noting that a handheld scanner is a manual scanner that can be moved over a document being scanned, but the only demerit is that an unsteady hand may cause the image to blur and one of the types of handheld scanners are barcode scanners used in stores. Sheetfed scanners are smaller than a flatbed scanner thus they can save on space but the downsides are that they require the user to feed the document into the machine, they tend to scan at a lower resolution than flatbeds and they can only scan single page documents thus they cannot be used to scan books or 3D objects. This slide scanner is a particular kind of scanners they need light to pass through them so that they can capture the image, unlike other scanners that need light to reflect off it.
