A multi-page sales report? Where do you want to store the images? Do you want to be able to edit them later? All these factors are critical to selecting the right one for your needs.

What Types Of Scanners Are There?
There are different types of scanners in the trade, which differ depending on the application in the selection of functions and construction:
- Hand scanners. These were the first affordable devices for the home user. The scanner (held in a typical T-shape) was simply pulled over a template. The application was a bit complicated, one only had to pull the device over a template very slowly and at a constant speed and without lateral deviations in order to get satisfactory results. For photos such scanners were unsuitable, the A4 format you had to start due to the low scan width, the device several times. Thereafter, the scanned document was assembled in an image editing program.
- Flatbed scanner. The best-known representative of the scanner family is the flatbed scanner. The operation of these devices is similar to that of a photocopier. Place a template on the glass of the scanner and fix it with a cover. Via a fluorescent lamp or LED sensors, the original is now scanned line by line and finally digitized. These devices are suitable for scanning photos, documents, and even books. With an upper transparency unit, you can even digitize negatives and slides on some models. Flatbed scanners are usually designed up to a size of DIN A4.
- Photo and slide scanner. With the help of a photo and slide scanner, as the name implies, you can digitize paper photos, negative strips, and slides in high quality. Good models achieve a scanning resolution of 4,000 dpi and more. Photo scanners have an automatic feeder for paper photos up to about 10 x 15 cm. The pure slide scanners, on the other hand, have corresponding receiving devices for individual slides or entire film strips.
- Fed scanner. Structurally, a retractable scanner is constructed similarly to a fax machine. These scanners are designed for batch scanning of documents and documents. Despite a high scanning speed, you can not edit other templates, which limits the functionality a bit. Feeder scanners offer a high scan resolution and a good scan speed and have compact dimensions.
What To Look For When Buying A Scanner?
Before you decide on a scanner, you should get acquainted with the most important purchasing features:
- Delivery. When buying a scanner, pay attention to the scope of delivery. In addition to the device and the power cord should also be a suitable USB connection cable, which is not always the case. Otherwise, you have to buy the cable separately. Furthermore, the delivery should include a driver CD and scanning software.
- The purpose. There are several types of scanners, so you should consider for now what you want to use the scanner in the future. If you just want to digitize paper photos, slides, and filmstrips for posterity, then a photo and slide scanner is the best choice. Above all, you scan documents and occasionally pictures, then you get along with the traditional flatbed scanner the best.
- Connectivity. Today’s scanners can be connected to other devices via USB as well as via WLAN. Some devices can even be controlled from a smartphone. Modern scanners also have a so-called Scan-to-Cloud and Scan-to-PDF feature.
- Scan resolution. This indicates how well the scanned image looks in the end and depends on the so-called dpi number. Dpi stands for “dots per inch” and represents the scanning resolution. A typical scanning device with a dpi value of 4,800 dpi, for example, is thus able to display a maximum of 4,800 characters per inch. Keep in mind that the higher the maximum dpi value of a scanner, the better the quality of the digitized images.
- Color depth. If you need the scanner mainly for private applications, then a color depth of 24 bits is sufficient. For professional use, you prefer to get at least a scanner with a color depth of 96 bits.
- Light source. A scanner needs a light source for operation. These are either cold light or LEDs. More and more scanners are being equipped with LEDs because they offer the advantage of using less power. LEDs also last longer than the cold light bulbs.
- Useful extras and additional functions. Some devices have various additional functions, such as the cleaning function. This is used in photos to produce outstanding image results. For cleaning, infrared units are processed, and some UV light is also used.
Which Accessories Can Be Useful For A Scanner?
After purchasing a scanner, you can alternatively purchase some accessories :
- The USB cable. This is probably the most important accessory for a scanner. In many cases, the USB cable is not included and must be purchased separately. Without a USB cable, communication between the scanner and the computer is not possible.
- Storage bag (for mobile scanners). For a mobile scanner, you’ll definitely need a padded storage bag to keep your device safe. For such scanners, you will get different transport bags and rucksacks on the market, all of which offer sufficient protection against damage.
- Cleaning spray and compressed air. For the scanners, there are special cleaning agents, with which you can clean not only the housing but also the document glass. Such cleaning sprays contain no chemical additives and do not attack the sensitive components and housing. A small can of compressed air can help you to clean the scanner.
