With the push of a button, a good color scanner can copy any type of document, report, or photograph you need transferred to the Internet or computer file. With the many different brands and types of scanners on the market, however, can you be certain which one you need for work or home use?

It may seem like a daunting task, but determining the type of scanner best suited for your work is not really difficult to do. A quick survey of the two major types of scanners can help you decide what computer hardware needs to be added to your home or work office before you spend too much money on something you don't need.

Here is a brief look at scanners:

The Sheet-Fed Scanner This scanner is reminiscent of the mimeograph of old, where a paper document is threaded into a rolling mechanism. As the paper moves through the scanner the information is collected and presented in its original format on your screen. Depending upon the accompanying software, the material may be presented in a word processing document or image viewer. The sheet-fed scanner is ideal for the person who doesn't have a lot of desk space to spare - these scanners are compact and easily portable. For people who have a need to scan book pages and magazines, however, this device will not work. Depending upon the brand, not all of these scanners may accept photographs.

Flatbed Scanners These scanners look remarkably like a copying machine with the similar glass surface and scanning mechanisms. Instead of producing a paper replica of the document, the material is transferred to the computer, into a word processing program or image editor. Flat bed scanners are perhaps the most versatile, as they can scan book pages, magazines, and photographs with ease. The only caveat to the flatbed scanner is size. These devices are large and bulky and do take up a lot of desk space. If you don't have much to spare, consider carefully the decision to buy one.

Usability, size and price are the main determining factors when buying a scanner. Consider your needs for scanner, and the space you can offer one, before you buy. A scanner can be a good investment for a business, just make sure it is the right one.

How Does a Document Scanner Work?

!±8± How Does a Document Scanner Work?

If you work with hard copy documents, you're going to need a document scanner a lot. Document scanners are of three types-flatbed, hand-held and sheet-fed. Of these, flatbed scanners work in a way that requires users to place the scannable document on the glass pane inside the device. Within the flatbed scanner lies an image sensor which moves down the page and copies its contents.

Hand-held scanners are used manually by the user. Here, the user must manually move the sensor over the length of the document so that it is scanned.

A sheet-fed scanner is just like a printer in the sense that it glides the sheet of paper over the sensor to get a scanned image of the page.

The CCD Sensor: Usually, scanners use a charge-coupled device (CCD) or a Contact Image Sensor (CIS) for its image sensor. However, drum scanners work with a photomultiplier tube as its image sensor. The image sensor of most document scanners comprises a range of charge-coupled devices. This refers to the device responsible for the movement of electrical charge from inside the device to a situation where it can be manipulated or converted into digital values.

This CCD range works through photo-sensitive diodes that convert light they catch into an electric signal carrying the same data. In flatbed scanners, the CCD array has a light within the scanner that brightens up the page and makes it easier for the array to read. Usually, sensors work in a three color mode - RGB. This means that the document's image will be separated into these three images - red, green and blue - by a lens before they are replaced when they can be seen on a computer.

The CIS Sensor: Here, the contact image sensor is different. It contains hundreds of RGB LED lights. When in combination, they become white light. To scan a document, the sensor is placed really close to the document with a glass pane separating them. When the document is scanned, it throws up white light. At this point, sensors pick up the image of the document.

Transfer to the computer: The scanning process ends with the scanned image being transferred to the attached computer. A document scanner can be attached to a computer by way of a USB, Small Computer System Interface, a group of computers connected to a common scanner or by FireWire. The language scanners understand and read is called TWAIN. These language drivers are usually accompanied by programs like PhotoShop and form part of the installation CD which comes with the scanner you buy.

Once the image is available on the computer, it can be put into different file types such as PDF for document viewing, or PNG which shows an uncompressed image with very high quality but which uses a lot of memory space, and JPG, another file compression tool that reduces the size of image files and consequently its image quality.

So, if you need a document scanner, choose wisely from the above types and ensure that you get the most out of it.
