Hi @Tomora
Welcome to the HP Support Community! We're here to help you get back up and running.
I am sorry your scanner has been disabled on your HP 4100 series printer. I understand how inconvenient it feels when scanning suddenly stops working, and I appreciate the effort you’ve already put in to try and resolve it.
Here are steps you can follow to enable the scanner again:
Step 1: Install or Open HP App
- Download the HP App from the Microsoft Store if not already installed.
- Launch the app and sign in with your HP account if prompted.
Step 2: Add Your Printer
- From the HP App home screen, select “Add Printer.”
- Choose your HP 4100 series printer from the list or enter its IP address if it does not appear.
Step 3: Access Printer Settings
- Once the printer is added, select it from the home screen.
- Go to “Printer Settings.”
- Scroll down to “Diagnose & Fix.”
- Run the tool—it will automatically detect and resolve issues such as disabled scanner functionality.
Step 4: Check Windows Device Manager
- Press Windows + X and select “Device Manager.”
- Click “View” > “Show hidden devices.”
- Expand “Imaging devices” or “Human Interface Devices.”
- If the scanner appears grayed out, right‑click and select “Enable device.”
Step 5: Update Drivers and Firmware
- Visit HP’s driver page for your printer:
https://support.hp.com/us-en/drivers/printers - Download and install the latest full feature software and firmware update.
- Restart both the printer and your PC after installation.
Step 6: Test Scanning
- Open the HP App again and select “Scan.”
- Place a document on the scanner glass and run a test scan to confirm functionality.
These steps should help restore your scanner and make it available again in Windows and the HP App.
