The computer does not see the scanner

There are times when the computer does not see the scanner, and there are many reasons for this phenomenon. Let's take a look at the most common ones and find out how to fix it.

The computer does not see the scanner: reasons

If the computer does not see the scanner, this does not always mean that one of the devices is broken. It may be necessary to install drivers or additional programs (the device simply cannot create a copy of the image in the standard way). Among the most common reasons why the computer does not see the scanner are:

1. The cable is damaged.
2. There are no drivers or they are outdated.
3. The scanner is not configured correctly.
4. The port is damaged.
5. The problem is in the system.

Cable damage

If the device does not work, first check the cable. Try switching the plug to another USB connector. Check the connection tightness. Inspect the cable and plug for external damage. Most often, the cable contacts stick (in the area where the plug is). Another problem is damaged insulation. If you know how to work with a soldering iron, try to repair it yourself. If not, take it to a service center or buy a new one.

Attention! You can also check the functionality of the cable by connecting it to another computer. You can buy a new cable if it is broken.

Lack of drivers

The most common problem, since all devices require drivers. Perhaps they are simply installed incorrectly. Insert the disc into the drive and install them. If there is no disk, download it from the Internet. But pay attention, there are many drivers, but you need those that are compatible with the devices. If the drivers are already installed, uninstall the old version before reinstalling. Don't forget to restart your computer.

Incorrect settings

Perhaps the settings are incorrect, then the computer cannot see the device. There is a high probability that other equipment is installed by default. Go to settings and open the list of equipment. Find your scanner and right-click on it. A menu will open where you need to select Use as default.

If this does not help, click on the equipment name with the left mouse button twice. Select the “Scanner” tab and uncheck the boxes next to “Stop scanning” and “Work offline.” Clear the queue.

Port damage

Another common problem. First, inspect the port for external damage. You can also check the connector by connecting other equipment, such as a flash drive or keyboard. If they work, the reason is different. If not, you will have to take the computer to a service center.

The system is not functioning well

Problem with system functionality. For example, the computer crashed. In such cases, you must make all settings default. You can also restart your computer. If this does not help, you should reinstall Windows.

Important! It is recommended to do this only as a last resort, having previously saved all data on another disk (system information will be formatted).

What to do if the computer does not see the scanner

If the computer does not see the equipment, do the following:

1. We try to move the cable to another USB connector.
2. We check the cable, plug and port for physical damage.
3. We check the power supply of the scanner itself.
4. Checking the network voltage. The device may not have enough power.
5. We turn off other devices that may block the operation of the equipment.
6. Checking for drivers.
7. We try to restart the computer.
8. We check in the settings whether we have selected the default scanner.
9. Rearranging

You may just need to install an additional application. Let's try one of the following:

1. The program can work with several devices simultaneously.
2. ABBYY FineReader. It's a paid application, but it can recognize images and texts. There is a free trial period.
3. A free program that can save data in PDF format.
4. Suitable if you need to transfer a lot of information.

If the scanner does not work, first check the cable, port and drivers. If you cannot determine the cause, you should contact the service center.
