The computer does not see the MFP scanner. Solved: The computer does not see the Canon MF226dn network scanner

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 multifunction printer/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 resolve them. If you are sure that the device scanner is in working order, then check it by connecting it to another PC. If nothing helps, then, of course, you will have to resort to the services of a service center.

Possible causes and ways to eliminate them

So, what to do if the MFP does not scan? First of all, pay attention to the computer, which together with the printing device must be turned off, and then disconnect the power cable from both devices. Wait about a minute, and after connecting the power again, turn on both devices. Thanks to such actions, the memory of the computer and multifunction device will be cleared, which will allow the MFP to operate normally.

But if the scanning still does not start, and the previously working multifunctional device began to produce various error codes, then be sure to eliminate them in a timely manner. You can find detailed descriptions of them in the instructions that came with the printer. In addition, a multifunctional device of almost any model makes it possible to perform scanning and copying in the so-called. service mode. To start it, first of all, turn off the device itself. Then hold down “Reset” and the “Power” button. Next, release the first button and press it twice (for different models, the number of such presses may be different - read the device’s operating instructions for more details). Finally, release "Power" and check if the printer begins to respond to scanning 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 connect it to another port on your PC. It is advisable to organize such a connection not through a USB hub, but directly to a personal computer. Then, first of all, check whether 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 that the printer prints but does not scan is 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 precisely for this reason, then either go to the website of the manufacturer of your office equipment and install it. If you don’t know what exactly to download, then it’s better to download the full device driver. In addition, the reason may even lie in the installed driver, which simply “flew”. In such a situation, you will have to first uninstall it and install the updated version.

If the printer prints but does not scan, you will have to reset its settings. This method will also 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. The problem can be solved by purchasing and installing a power supply with similar characteristics.

In general, it is not uncommon for the printer to work, but the MFP scanner does not function. This problem especially takes the user by surprise when a printer that is still printing normally fails. According to some specialists, the MFP scanner may stop functioning due to the creation of microwaves by any objects. Therefore, before using the device for printing, it would be a good idea to turn off the microwave oven - perhaps this will help you.

In addition, if the printer works, but the scanner itself does not, then check the grounding of the wiring, the voltage in the network, and carefully inspect the wire connecting the PC to the scanner for visible damage.

Often, printer owners encounter one of the very common problems and then try to figure it out and understand why the Canon printer does not scan at all or has stopped scanning now. The reason for such a problem can be very different, for example, sometimes it lies in the printer, or sometimes the printer is fine, and all is due to the personal computer, since it is either a driver error or the printer is not connected to the computer correctly. In order for us to be able to find the cause of the problem and figure out why our scanner is not working at the moment, we just need to consider several of the most logical reasons, and after we find them, we need to try to eliminate them programmatically. First, you should make sure that the installed scanner is currently in stable working condition, and then you need to check it by connecting it to another personal computer. If these did not help, then the best solution, of course, is to turn to the services of service centers.

Now we will look at the most possible reasons, and also talk about methods that will help eliminate them. So what should you do when the printer stops scanning?

Why won't my Canon printer scan?

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 connect it to another port on your PC. It is advisable to organize such a connection not through a USB hub, but directly to a personal computer. Then, first of all, check whether 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 that the printer prints but does not scan is 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 precisely for this reason, then download the appropriate drivers from our website or from the website of the manufacturer of your office equipment and install it. If you don’t know what exactly to download, then it’s better to download the full device driver. In addition, the reason may even be an installed driver that simply “failed.” In such a situation, you will have to first uninstall it and install the updated version.
Scans another device - a scanner. It is he who can convert various images, documents and other things into electronic format (digitize).

It's another matter when the scanner and printer are combined in one device. In this case, the question is completely justified (let’s pay attention to the curvature of the wording)
Canon printer does not scan, what should I do?
Everything is very individual, so I won’t talk about the reasons without seeing the patient. I'll give you a couple of general tips that can help.
Replacing the cable with a shorter one
In some cases, changing the USB cable to a shorter one can help. The trick is that some peripherals may not work correctly when the cable length is more than 1.5 m. Some devices work, while others fail. Technomagic, in a word.

Installing the latest drivers
Any printer brand has its own official website, from where you can download the latest drivers. Sometimes the drivers that came with the purchase become outdated (for example, when the user changes OS) and stop working and new ones are needed.
Correct setup and connection
Do everything according to the instructions, do not forget to make the printer the “default printer” (go through the control panel and change it)
The cartridge is not stitched correctly
Printing problem? If difficulties arise after refilling the cartridge, it is not stitched correctly.
Clear the “print queue”
The fact is that with combined devices (printer-scanner-copier), simultaneous performance of functions may be technically impossible. Those. it will not be able to print and scan at the same time.

Welcome! This blog is dedicated to the Internet and computers, or rather was dedicated to them.

It’s probably immediately obvious that no new articles have appeared on the site for many years. Yes, this is the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others writing at that time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, of those blogs that were created simultaneously with mine, most have already disappeared into eternity. And I just simply didn’t have enough time to blog. So yeah, it's not updated anymore. Although we once won the “Runet Blog 2011” competition with this site.

I even had the idea of ​​deleting all this, but then I reviewed the old materials and realized that they could still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will be marked accordingly), but the site, for example, can be useful for beginners - here you can read about the basic concepts of the Internet, learn how to set up the Internet, Windows, or even decide to switch to Linux. So take a look at the categories and choose the one that suits you.

And yet, I hope that this is more than just a blog, but a real guide to the Internet. The site can be viewed in directory mode, where all available articles are structured by categories. And, who knows, maybe one day new high-quality articles will start appearing here.

Modern Android phones are more than just phones. You get used to the set of installed programs, the history of your calls and text messages, your collection of photos and much more. But time passes, and the device that you were completely satisfied with begins to slow down, glitch, or simply loses its presentable appearance due to chips on the body or scratches on the screen. The question arises of choosing a new phone and changing the Android phone. And if we ignore the issue of choice for now, then “moving” to a new phone remains a serious problem - you absolutely don’t want to start all the data from scratch. This is what we will talk about today.

Most of the readers of this blog have most likely never encountered version control systems and will not encounter them in the near future. It's a pity. This extremely convenient invention is quite widely used by programmers, but, in my opinion, it could also 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 of interest to all readers.

If you have been wondering how to watch movies online and access the Internet from your TV, 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, this is why Google recently demonstrated an absolutely stunning device that immediately became a sensation. We're talking about the Chromecast media streamer, a more advanced and affordable version of last year's disastrous Nexus Q player.

The Chromecast dongle, whose dimensions do not exceed 2 inches, connects to the HDMI port of the TV and allows you to enjoy watching 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 design of Android system memory, problems that may arise due to its lack and ways to solve them. I myself recently encountered the fact that my Android phone began to regularly display messages about low memory when I tried to install this or that 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 using an additional memory card. However, there was a problem, and it took a lot of fiddling around before I found the right solution that didn’t require root access or completely restoring the phone to its factory state.

MFP Canon i-SENSYS MF226dn

An unexpected problem occurred in one of the offices with network scanning; the Canon MF226dn network scanner stopped working on a couple of computers.

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.

At the same time, scanner drivers were installed on the PCs themselves, the scanner access program ScanGear was launched, and the scanner was visible over the network.

As it turned out, on one of the PCs the problem arose after installing the next big Windows 10 update; on the other, the OS was reinstalled and the drivers were installed from the original disk.

The device drivers were reinstalled from the original disk, network access to the scanner was checked, the influence of antiviruses and the firewall was checked, but the Canon i-SENSYS MF226dn MFP still did not display two PCs in the scanning list.

The problem turned out to be known to the manufacturer and there is a patch on the official Canon website that corrects this problem.

By the way, according to the description of the fix, the problem may also occur with a regular USB connection to the Canon MF226dn MFP, and it will also appear again with the next Windows update, after which you will have to apply this fix again.

You can download the patch that corrects the Canon MF226dn network scanning problem from the official website.

Also, for network scanning to work successfully, the Canon Tool Box program must be installed on the PC, and when updating the Tool Box, you may encounter the following error - on the scanner you select the PC you need, start the scanning process, but it ends with an error. At the same time, the Tool Box application is launched on the PC.

To fix this situation, also run the above fix.
