Scanner is one of our most-used office devices. It scans or takes an image of the document and presents it on the computer screen. If your scanner is not working properly, it can cause inconvenience at work. But don’t worry, it’s easy to fix. Please follow this troubleshooting guide to make your scanner work again.

  1. Re-add your scanner
  2. Check your scanner services
  3. Update your scanner driver
  4. Run Hardware and Devices troubleshooter
  5. Perform a clean reboot
  6. Run SFC and DISM

Before we start troubleshooting, please make sure your scanner is connected properly to your computer. You have to check the cables if you use a wired scanner, and check the network if you use a wireless one. Then, try to restart your computer and your scanner. If nothing helps, then continue the troubleshooting. (Please note that all the screenshots in this guide are taken on Windows, but the instructions also work on Windows.)

1. Re-add your scanner

When there are incorrect configurations of your computer, your scanner might not work properly. To check, you can remove your scanner first, and then add it back to your computer. This helps resolve the scanner not working issue.

To do this:

  1. Click Start on the system tray bar and select Settings.
  2. From the left panel, select Bluetooth & devices, and then go to Printers & scanners.
  3. Select your scanner from the list.
  4. Click Remove.
  5. Go back to the Printers & scanners list. Select Add device and follow the on-screen instructions to re-add your scanner.

Now, check if your scanner works again. If the problem persists, go on to the next troubleshooting tip.

2. Check your scanner services

In order that the scanner can function properly, Windows requires some services enabled and running in the background. For example, the Windows Image Acquisition service (WIA for short) enables imaging/graphics applications to interact with your scanner.

So, when your scanner stops working, you can check if some of the related services are disabled or stopped. If this is the case, re-enabling the services would help. To do so:

  1. On your keyboard, press the Windows key and R to invoke the Run prompt. Then, type services.msc and hit Enter.
  2. Scroll down the service list until you see the Windows Image Acquisition (WIA) service. Double-click this service to adjust settings.
  3. Click Startup type and select Automatic. Then, click Apply and OK.
  4. Repeat the above steps for the following services: Remote Procedure Call, DCOM Server Process Launcher, RPC Endpoint Mapper, and Shell Hardware Detection services.

  5. Once done, restart your computer.

Now you can try using your scanner again. If it still doesn’t work, try the next solution.

3. Update your scanner driver

When your scanner still cannot work, one of the first things you should do is update your scanner driver. To update your scanner driver, here’s what you can do:

  1. On your keyboard, press the Windows key and X at the same time, select Device Manager.
  2. Double-click to expand the category Print queues. Then right-click your scanner device and click Update driver (the name of the device can be different on your computer).
  3. Then click Search automatically for updated driver software.
  4. Wait for Windows to find the latest driver available for you.
  5. When the driver update is done, restart your computer for the change to take effect.
  6. Then check and see if the problem is fixed.

Sometimes Windows may tell you that “the best drivers for your device are already installed”. However, it’s not always accurate since Microsoft doesn’t have access to all the newly released drivers for your devices.

Therefore, if Device Manager doesn’t find you the latest scanner driver, we recommend using Driver Techie to scan and repair outdated, corrupt, or missing drivers. It works in most cases where you have a driver-related issue. You can download Driver Techie by Clicking Here or following the guide below.

To use Driver Techie to find you the latest scanner driver:

4. Run Hardware and Devices troubleshooter

Windows OS has built-in troubleshooters which help users to detect and repair some common computer issues, including hardware glitches. If your scanner is not working properly on Windows 11/10, try this hardware and devices troubleshooter and see if it helps.

To do so:

  1. On your keyboard, press the Windows logo key and R together to invoke the Run prompt. Then, type msdt.exe -id DeviceDiagnostic and press Enter.
