The 1860s saw the invention of the first scanners. However, Russell Kirsch at the American National Bureau of Standards invented the scanner as we know it today in 1957.
What is a Scanner?
A document scanner is a device that can digitally copy physical objects and upload their images to computers. It can be a standalone machine or a component of a larger multipurpose gadget. It helps to create an electronic version of the document which can be viewed and edited on a computer.
The majority of scanners are connected to computers using cords that plug into a port that is readily accessible. It can also be networked so that it can work with multiple computers without being directly linked to each one.
What is a Scanner used for?
A scanner is a crucial piece of computer hardware that uses light sensor technology to scan and transform a physical image or document into a digital one that can be read by a computer. The scanners can scan black-and-white or colour documents. There are high-resolution and low-resolution scanners on the market, and you can select the one that best suits your needs.
- One of the most frequent applications for a scanner is copying. A poster, worksheet, brochure, or other documents can be copied several times using a scanner so that they can be printed as often as required. It will operate as though your computer were linked to a printer. A scanner also gives users the advantage of editing documents before printing copies, which is not available with a copier
- Another popular application for scanners is digital archiving. It is a technique for creating and storing digital copies of hard copies of documents. These documents include business records, tax paperwork, personal documents, and family letters
- It allows you to make changes to your document before printing it if necessary
- Scanners enable you to convert hard copies of photos into digital copies that can be shared with friends and family via the internet
- Many facts and figures required for research projects for school, college, or professional use can be found in books borrowed from the library or other sources. We can use a scanner to capture the key pages and store them in a computer so we can access them as needed
- Users of scanners can also use the internet to send copies of photos to friends and family. Although digital photography has become the standard format for both amateur and professional photographers, many people still have old family photos that were taken with conventional film cameras and were never recorded digitally.
What are the different types of scanners?
Once the scanner is set up, all you have to do is choose whether to scan in colour or black and white and whether the document is made up of photos and text. The file may then be saved to your computer or sent via the internet. These devices come in a variety of designs, such as automatic document feeders, sheet-fed and flatbed scanners, camera scanners, and handheld scanners.
Flatbed Scanner
The most common type of scanner is a flatbed scanner. The term "flatbed" refers to the fact that the document is scanned on a flat surface. Flatbed scanners are more versatile than sheetfed scanners and can scan documents of various sizes.
It is placed on a flat desk and has a lid that can be opened in order to see the glass through which the document is being scanned. The moving light-capturing sensor, typically a CCD or CIS display, is placed below the glass with the document resting on top of the glass. The moving sensor captures the image and converts it into digital format while the light source illuminates the glass during the scanning process.
These scanners are capable of scanning DVD cases as well as books, articles, and newspapers. They are also better for scanning photos if you have a high-resolution scanner. Other flatbed scanner models may come equipped with cutting-edge functions like Bluetooth or wireless connectivity and automatic document feeders.
Photo Scanner
If you want to scan pictures, images, and old photographs, you should use a photo scanner because they produce high-quality results. Although other scanners can scan images, photo scanners produce far superior results in terms of colour depth and when scanning a large number of photographs. It has a high resolution and colour depth. They are more compact than general-purpose scanners. Some photo scanners include image editing software that can be used to clean and restore old photos.
Document Scanner
These scanners are used specifically for scanning numerous documents that are large in size. Given that the documents are fed into the device rather than being placed on the flatbed glass, it is also known as a sheetfed scanner. It is the best option when you need to scan a lot of pages every day but only have a small amount of workspace. Some sheetfed scanners have cutting-edge features that speed up and increase the scanning process' effectiveness. They are therefore more expensive than flatbed scanners.
Portable Scanner
Portable scanners are useful and frequently small enough to fit in your pocket. They work well for scanning text-based documents. They come with a wireless facility as well. They can be used to scan images and edit them, scan documents and create PDFs, and even scan bar codes. Compared to flatbed or photo scanners, portable scanners are excellent at digitizing documents but fall short when it comes to scanning photos.
Other types of computer scanners
Utilizing a scanner is quite easy and doesn't call for any complicated setup or configurations. Hewlett-Packard, Microtek, Relisys, and Epson are a few well-known scanner producers. Other types of scanners include;
- Handheld Scanners - They are made for scanning documents on the go, like printed photos or newspaper articles. drag the scanner over the page you want to scan to begin scanning the text and images
- Drum Scanner - Offers faster scanning by turning the scanned page around a drum. For quicker scanning, rotate the scanned pages around the drum
- Sheetfed Scanner - They are made to scan each document that is fed into the scanner one after the other
- Film Scanner - Scans film from cameras and upload the data to a computer. The photographer can directly handle a number of tasks, including determining the original image on the film's aspect ratio, cropping, adjusting, and more
- Pen Scanner - A tool that can be used to drag over text and scan it into a computer, slightly bigger than a pen that you would use to write
- 3D Scanners - These are somewhat distinct from conventional scanners in that they gather distance point measurements from a physical object and convert them into a virtual 3D object
What are the major advantages?
There are many benefits to using a scanner, and modern multifunction printers are built with powerful scanners, allowing you to scan documents without purchasing any additional equipment. Additionally, they don't take up so much space.
- Cost saving: One of the scanning's biggest benefits is the transformation of physical files into digital ones. In addition to saving physical space that would otherwise be used for storage, using a scanner also benefits the environment
- Reliability: Scanning involves the conversion of physical images into digital formats. They are not reliant on two-way communication, this aids in transmitting or storing crucial information
- Ease of Use: Scanners are simple-to-use electronic devices. Modern multifunction printers have built-in scanners that can be used freely and carelessly. Because most settings are automatically adjusted and fine-tuned, users only need to choose the most basic options, such as document or photograph or colour versus black and white. After scanning is finished, you can also transfer the file to a computer or an email account. Users can also save the scanned file in a different format, like PDF files
- Quality: Scanners are able to reproduce images with great accuracy and resolution. For digital photos, scanning ensures the highest resolution possible, whereas fax machines may find it difficult to replicate accurate details. Scanners are also more beneficial in the fields of engineering and photography
- Efficiency: Modern scanners are convenient and easy to use, and they are made to operate more quickly and effectively.
