Often, office equipment users are faced with the need to find an answer to the question of why the printer does not scan. The cause of the problem may lie in the MFP / printer and personal computer, or in the connection between them. To find the source of the problem and determine why the scanner is not working, you need to look at several possible causes and try to fix them. If you are sure that the scanner of the device is in working order, then check it by connecting to another PC. If all else fails, then, of course, you will have to resort to the services of a service center.
Possible reasons and ways to eliminate them
So what if it doesn't scan the MFP? First of all, pay attention to the computer, which, together with the device for printing, must be turned off, and then disconnected from both machines. Wait about a minute, and after reconnecting power, turn on both devices. By doing this, the memory of the computer and the multifunction device will be cleared, allowing the multifunction device to operate normally.
But if the scan did not start, and the previously working multifunctional device began to issue various error codes, then be sure to eliminate them in a timely manner. You can find their detailed descriptions in the instructions supplied with the printer. In addition, a multifunctional device of almost any model makes it possible to scan and copy in the so-called. service mode. To start it, first of all, turn off the device itself. Then hold down the "Reset" and the "Power" button. Then release the first button and press it twice (for different models, the number of such clicks may be different - read more in the device's instruction manual). Finally release “Power” and check if the printer is responding to scan commands.
If the printer does not scan and the above recommendations did not help you, then be sure to try reconnecting the USB cable. Pull it out and plug it into a different port on your PC. It is advisable to organize such a connection not via a USB hub, but directly to a personal computer. Then, first of all, check if the PC can see the printing device connected to it. If the printer has become visible to the computer, then try scanning and printing a couple of sheets. 
Another reason the printer prints but doesn't scan is because of the scanner drivers that the user simply forgot to install. The question arises, what to do in this situation? So, if the PC does not see the scanner for this very reason, then either from the website of the manufacturer of your office equipment and install it. If you do not know what to download specifically, then it is better to download the full device driver. In addition, the reason may even lie in the installed driver, which simply crashed. In such a situation, you will have to first remove it and install the updated version.
In the event that the mfp prints but does not scan, you will have to reset its settings. Also, this method will help in solving the following problems: the printer does not copy, has stopped responding to user commands. You should reset the settings from the device menu or using special software.
In addition, the device may stop scanning due to a breakdown of the power supply - most models are connected to the electrical network using a similar part, just like mobile phones. You can solve the problem by purchasing and installing a power supply unit with similar characteristics.
In general, it is not uncommon for the printer to work, but the MFP scanner is not functioning. Especially such a problem catches the user by surprise when a normally printing printer still fails. According to some specialists, the mfp scanner may stop functioning due to the creation of microwaves by any objects. Therefore, it would be a good idea to turn off the microwave oven before using your printer to print - it may help you.
In addition, if the printer is working, but the scanner itself is not, then check the grounding of the wiring, mains voltage, and carefully inspect the wire connecting the PC to the scanner for visible damage.

More precisely, on the Canon i-SENSYS MF226dn MFP itself, two computers from the office network no longer appear in the list of devices available for scanning.

If the problem is solved, one of the ways to say "Thank you" to the author is indicated -.
If the problem cannot be resolved or additional questions have appeared, you can ask them on ours, in a special section.
Quite often, users contact the service center with the following problem: the computer does not see the scanner / MFP. Due to the fact that the problem is popular, there are many options for solving it. Below are five powerful ways.
Is the connection OK?
Typically, the problem described is caused by a damaged cable or incorrectly inserted cable. First of all, you need to check whether the connection is reliable, whether the correct USB connector is used, whether it is working. You can try plugging the cable into the port where the mouse or keyboard is connected. Some printers have a power button hidden on the back of the case. You need to press it. If the connection still does not appear, then you should proceed to the second method of solving the problem.
Are the drivers installed?
The computer does not see the Canon (or any other manufacturer) scanner if the correct drivers are not installed on it. Sometimes they can be wrong. In order to reinstall them, you should use the disk that came with the scanner. If for some reason it is not there, then you can use the official website of the technique. The manufacturer must load drivers for it. It is important to choose the right ones that fit both the hardware and the operating system. If the drivers are installed, but do not work correctly, then before reinstalling them, you need to uninstall the original version.
What are the settings?
Sometimes the computer cannot see the scanner due to certain settings. It may be that another device is assigned by default. You need to go to the settings, to the list of equipment. After that, find the name of the scanner and click on it with the right mouse button. In the menu you need to select "Use as default". Sometimes this method is effective.
In the event that the problem remains unresolved, you should double-click on the name of the device. After that, you need to select the "Scanner" tab and uncheck (if any) next to the "Autonomous work" and "Stop scanning" settings. It is advisable to clear the queue.
Is the system functioning normally?
It is not uncommon for the computer to not see the scanner due to a system failure. In most cases, you have to return the PC to factory settings so that the problem with the incorrect operation of the scanner is solved. Many users note that this method almost always works, but not everyone decides on it.
Sometimes rebooting the hardware and computer is enough.
Are the ports healthy?
Sometimes there is a problem with ports. In order to check them, it is enough to connect something else (keyboard, mouse). If another technique works, then the problem is still in the scanner. If it doesn't work, you will have to take the PC for repair, and this will require additional funds.
conclusions
If your computer can't see the scanner, don't despair. Before you start to panic, you need to make sure that the cable is working and connected correctly. The printer must also be operational. If there is a need to download and further install the drivers, you must be sure to read every word during installation. Usually there is written instructions and what actions the user needs to perform. When installing, be sure to pay attention to the compliance of the drivers with the system and technology, otherwise the problem with inoperability may remain relevant. If the methods did not help, it is better to contact the service center.
Before taking the device to professionals, you still need to try all the above methods - they will not bring any harm to the equipment. You may be able to fix the problem yourself.
Welcome! This blog is about the Internet and computers, or rather it was dedicated to them.
Probably, you can immediately see that there have been no new articles on the site for many years. Yes, that's the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others who wrote at the time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, then of those blogs that were created at the same time as mine, most have already disappeared into eternity. And I just didn't have enough time to blog. So yes, it is not updated anymore. Although once we with this site won in the competition "Blog of Runet 2011".
I even had an idea to delete all this, but then I reviewed the old materials, and realized that they can still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will receive appropriate notes), but the site, for example, can be useful for beginners - here you can read about basic concepts of the Internet, learn how to configure the Internet, Windows, or even decide to switch to Linux. So look at the rubrics and choose the one that's right for you.
And yet, I hope this is more than just a blog, but a real guide to the Internet. The site can be viewed in the directory mode, where all available articles are structured by category. And who knows, maybe one day new high-quality articles will start appearing here.

Modern android phones are more than phones. You get used to the set of installed programs, the history of your calls and text messages, the collection of photos and much more. But time goes by, and the device that suits you completely starts to slow down, glitch, or simply loses its presentable appearance due to chips on the case or scratches on the screen. The question arises of choosing a new phone and changing the android phone. And if we now bypass the question of choice, then "moving" to a new phone remains a serious problem - we absolutely do not want to start all the data from scratch. That's what we'll talk about today.
Most of the readers of this blog, most likely, have never encountered version control systems and will not come across any in the near future. It's a pity. This extremely convenient invention is widely used by programmers, but, in my opinion, it could be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for "office" (Microsoft Office) work. Nevertheless, I think that the material presented in the article may be interesting for all readers.
If you have thought about how to watch movies on the network from your TV and go online, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, therefore, recently the Google corporation demonstrated an absolutely amazing device, which immediately became a sensation. We're talking about the Chromecast media streamer (Chromecast), a more advanced and affordable version of last year's disastrous Nexus Q.
The Chromcast Dongle, which is less than 2 inches in size, connects to your TV's HDMI port and lets you enjoy streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on the operating platform iOS, Windows, Android or Mac OS.
This article is devoted to the device of the android system memory, the problems that may arise due to its lack and how to solve them. I myself recently came across the fact that my android phone began to regularly give out messages about insufficient memory when trying to install an application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume with an additional memory card. However, there was a problem, and I had to tinker a lot before I found the right solution, which did not require root access or completely restore the phone to its factory state.
