Use HP Print and Scan Doctor (Windows)

Use HP Print and Scan Doctor on your Windows computer to help diagnose and fix printing and scanning issues. Make sure paper is loaded in the main tray, and then turn on the printer. Download HP Print and Scan Doctor, and then follow the prompts to install and open the tool.

If a Firewall on your computer is active, it may be rejecting the necessary network connection needed for the network scanning software to operate properly. Disable the Firewall on your computer and try the network scanning again. Temporarily change your firewall/security settings to allow network connection.
In the Settings window, go to Devices > Printers & scanners. Under the Add printers & scanners section, select the Add a printer or scanner button. Wait for the computer as it tries to find nearby devices, both connected directly to your computer or via the network.
Check the network connection status in the HP Smart app

Confirm the printer is connected to the internet and ready in the HP Smart app. Open the HP Smart app, wait a few minutes for the printer to connect to the app, and then check the connection status next to the printer icon.

Open the HP Print and Scan Troubleshooter

Make sure the printer is on and connected to your laptop. Select HP Print and Scan Doctor on the HP Customer Support page to download the troubleshooter. Click HPPSdr.exe to open the software`s window. Click Start and select the printer that doesn`t scan.

When a computer does not recognize an otherwise functioning scanner that is connected to it via its USB, serial or parallel port, the problem is usually caused by outdated, corrupted or incompatible device drivers. This is usually easily remedied by obtaining and installing new drivers.
If the scanner driver is having problem, the scanner cannot scan correctly. So updating the driver may resolve the problem. You can go to your scanner`s manufacturer`s website to download the latest Windows 10 driver. For some models, manufacturer might not release Windows 10 driver.
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
Step 1: Unplug the power cord from the scanner. Step 2: Using a soft, lint-free cloth, like a microfiber cloth, wipe off the dust from the scanner glass. Step 3: If the glass has smudges or other contaminants, use a little bit of glass cleaner on a microfiber cloth and wipe the glass.
Open the HP Print and Scan Troubleshooter

Make sure the printer is on and connected to your laptop. Select HP Print and Scan Doctor on the HP Customer Support page to download the troubleshooter. Click HPPSdr.exe to open the software`s window. Click Start and select the printer that doesn`t scan.

In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
