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 a large number of options for solving it. Five effective methods are described below.
Is the connection OK?
Typically, the described problem occurs because the cable is damaged or incorrectly inserted. First of all, it is necessary to check whether the connection is reliable, whether the correct USB connector is used, whether it is working. You can try inserting the cable into the port into which the mouse or keyboard is connected. Some printers have a power button that is hidden on the back of the chassis. You need to click it. If the connection still does not appear, then you should proceed to the second method of solving the problem.
Are drivers installed?
The computer does not see the Canon scanner (or any other company) if the necessary drivers are not installed on it. Sometimes they can stand 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 equipment. The manufacturer must download drivers to it. It is important to choose the right ones that suit both the hardware and the operating system. If the drivers are installed, but do not work correctly, then before reinstalling them, you must remove the original version.
What are the settings?
Sometimes the computer does not see the scanner due to certain settings. It may be that another device is assigned by default. You must go into the settings, in 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 by default." Sometimes this method is effective.
In the event that the problem remains unresolved, double-click on the name of the device. After that, select the “Scanner” tab and remove the checkmarks (if any) next to the settings “Offline operation” and “Scan stop”. It is advisable to clear the queue.
Is the system functioning normally?
Often, the computer does not see the scanner due to a failure in the system. In most cases, you have to return the PC to the factory settings so that the problem with the incorrect operation of the scanner is solved. Many users note that this method works almost always, but not every person will decide on it.
Sometimes a reboot of the equipment and the computer is enough.
Are ports OK?
Sometimes there is a problem with the ports. In order to test them, just connect something else (keyboard, mouse). If another technique worked, it means that the problem is still in the scanner. If it does not work, you will have to take the PC to repair, and this will require additional funds.
findings
If the computer does not see the scanner, do not 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.
