Wand scanners are also called handheld scanners due to their design and size.
They are quite a peculiar little machines.
They are small and portable scanners that you can easily carry around.
Wand scanners are excellent if you need to digitize document on the go. They can deal with photos, documents, books anything with a flat surface and convert them into digital data.
In this article we will talk about how does a want scanner work.
You can learn about the best wand scanners here.
It’s a bar-shaped scanner that usually runs on batteries. The scanner works with a detector array which consists of tiny light sensors formed into the line.
When you roll the scanner over a flat surface, it illuminates it with a light, and its smart sensors pick up the data or text as a set of points of light.
The rollers on the surface of the scanner touch the page and measure its length, allowing the scanner to scale the image correctly.
Once the information is captured, it works like any normal scanner.
Its electronic circuitry converts the point of lights into color or grayscale signals and turns them into digital data.
Electronic circuitry assigns a number value to each color like blue, red, or green and saves the digital file to an SD card.
How to Use a Wand Scanner for Scanning a Document?
As we have just noted, a wand scanner works by sliding it over a flat surface.
Let’s see how it works in detail.
The following steps may or may not be relevant to all wand scanners. However, most wand scanners have more or less the same functionality.
Therefore, without further ado, lets see how does a wand scanner work.
- 1As this portable scanner works on batteries, so make sure it includes the required battery or if it has a rechargeable battery then make sure that it is charged.
- 2Turn on by pressing the power button on the scanner.
- 3Make sure the SD card is in its slot, if not, insert it in its slot on the scanner to save the scanned information.
- 4You can set date and time so that your scanned files show the correct time stamp.
- 5Press the resolution button and select your required resolution for scanned pages. It should depend on what you want to scan. If you want to scan a photo, then set the high-resolution result, and for normal book pages or documents, you can set low resolution. Keep in mind a high-resolution file will take more space and if you need to scan a few documents, you don’t need it at all.
- 6Place the document on a flat and hard surface like a table.
- 7Place the scanner over the paper with LCD screen face up so you can see the image of the page. Set the length width as you require. The portion of the page you want to scan should be between the width markers of the scanner.
- 8Press power/scan button and while holding the paper to its place with a hand slowly slide the scanner evenly over the surface of the page.
- 9Press the power button again when you reach the end of the document.
- 10Now you can see the scanned page on the LCD screen (if it has a large one), make sure it is scanned properly before you leave the premises.
- 11Back when you are at your computer connect the scanner to the computer with a USB cable.
- 12Transfer the file from SD card to the computer and save it as your required file format.
- 13You may need to run it through an OCR software if it is a text file to convert the file into an editable text file. Not all wand scanner comes with OCR, and most of them required the document to be converted through computer software.
