The imaging principle of printer scanners is mainly composed of optical imaging parts, mechanical transmission parts,s and conversion circuits. These parts cooperate to convert the optical signal reflecting the image characteristics into an electrical signal acceptable to the computer.
The optical imaging part is the scanner’s critical part, commonly referred to as the mirror group. The scanner’s core is the photoelectric conversion component that completes the photoelectric conversion; at present, the photoelectric conversion components used in most scanners are charge-coupled devices (CCD), which can convert the optical signal irradiated on it into the corresponding electrical signal. Open the black upper cover of the scanner; you can see mirror strips, lens components, and CCD inside. In addition to the core CCD, other main parts include a light source, optical path, and lens of the visual imaging part. The conversion circuit is commonly known as a machine motherboard, which is responsible for completing the servo work of all circuits and a / D conversion workers. Of course, it also includes the processing of digital signals by the mirror group. The mechanical transmission consists of a stepping motor, a scanning head, and a guide rail. It is mainly responsible for the main board sending instructions to the stepping engine to drive the belt to make the mirror group move according to the track to complete the scanning.
When the scanner works, the light source first shines on the artwork to be input, Generating reflected light (reflected draft) or transmitted light representing image features (transmission draft). The optical system collects these light rays and focuses them on the CCD. The CCD converts the optical signals into electrical signals. Then the circuit part performs a / D conversion and processing to generate corresponding digital signals and transmit them to the computer. When the mechanical transmission mechanism drives the scanning head equipped with the optical system and CCD to move relative to the drawing under the control of the control circuit, Scan all the pictures, and a complete image is an input into the computer.
1、. What are the advantages of a printer scanner?
A printer scanner is an input device that can input image data into the computer. Pictures, photos, films, drawings, and various documents can be input into the computer by the scanner. Scanners are widely used in the field of office automation. Now, more and more image information is obtained through computers. Data show that document management is the most commonly used field of scanners. To properly apply knowledge, all documents can be scanned, accessed, edited, output, and transmitted by a scanner with relevant processing software.

2、. How to install the printer scanner?
Printers and scanners are becoming more and more popular. Although some families bought a printer, for various reasons, such as the computer breaking down and reinstalling the system, the printer will not work since then. Many printers have scanners. Some people can’t even find the scanner. Where is the program? [2]Add a printer or scanner in Windows
1. Find two wires. One is the power cord. Plug it in.
The other is a USB data cable plugged into the computer like a USB stick.
2. Install the printer driver.
You don’t need to look for a driver like looking for a needle in a haystack on the Internet.
Now the driver management software is brilliant. They will automatically install the appropriate driver for you.
Such as driving elves, driving life, 360 driving masters, etc. You can find anyone.
As long as you open the driver management software, it is brilliant and requires little manual intervention,
In a moment, the printer and scanner drivers are found. You need to click the mouse: install.
3. Try printing
Try to find a word document,
The problem may be that the computer doesn’t know which printer to choose among many similar printers.
Now, we need to select the correct printer manually.
But it’s a little annoying. You have to choose the correct printer every time you print in word.
4. Set default printer
Let the computer know this printer, rather than let me choose the correct one again and again.
You’d better find the printer in the control panel and right-click to select the default printer.
This is the end of the printer setup. Here are two ways to use the scanner.
5. Where is the scanner
Or find the printer in the control panel and then double-click it, as shown in the figure, to find the scanner.
Click “scan photos or documents.”
6. Set up a desktop shortcut for the scanner
It’s not a good idea to find a scanner in the control panel every time. Put the scanner on the desktop!
Right-click and scan directly.
3、. How does the printer scanner scan files?
During daily work, we often encounter problems that cannot be communicated directly due to geographical reasons. For example, after the contract is negotiated, both parties cannot sign face to face. At this time, we need to scan the documents for the other party to reach an agreement. [3]4 Ways to Scan Documents
1. Turn on the printer and computer, determine the documents to be scanned, turn over the records, and put them in the position when the printer copies.
2. Close the cover of the printer, go back to the computer, right-click “My Computer,” and click the last item, “properties.”
3. After entering the properties, click “control panel” at the top left and enter the “adjust computer settings” interface.
4. On the open interface, find “equipment and printer” and click to enter.
5. The connected printer will have a sign at the bottom left, so find the connected printer device.
6. Place the mouse over the printer icon, right-click; a window will appear and select the “Start scanning” item.
7. After clicking, an interface will pop up. Click “Preview” at the bottom to see the picture effect. You can adjust it or change the picture resolution if it is too dark or too bright.
8. After adjustment, click “scan,” and a scanning progress bar will appear on the computer. After it is scanned, you can.
9. After scanning, a dialog box appears at the computer’s bottom right. You need to enter the exact name of the file and then confirm.
10. The file is saved on the desktop by default in the form of a folder. Click in to see the scanned image.
Note: the larger the resolution adjustment, the slower the scanning speed.
