If your computer can't find your scanner, the connection, driver, or network discovery settings are the most likely causes.
Confirm the printer and computer are on the same network, then reinstall the scanner driver if it still isn't detected.
Common Reasons my scanner not detected
A network mismatch
Wireless scanners need the same network connection as printing, and can fail separately even if printing works.
A missing scanner driver
Some systems install a print driver automatically but skip the scanner component.
Quick Checks Before Troubleshooting
- Confirm printing works fine, to isolate the issue to scanning specifically.
- Check for the scanner listed separately in Devices and Printers or Image Capture.
1. Confirm Network Connection
Make sure the printer/scanner is on the same WiFi network as your computer.
2. Reinstall the Scanner Driver
Download and install the scanner-specific driver package from the manufacturer.
3. Restart the Printer and Computer
A fresh restart often resolves a scanner that print functions alone don't fix.
4. Check Third-Party Scan Software
Confirm any scanning app you're using recognizes the correct device from its own device list.
What If It's Still Not Fixed?
If you've worked through every step above and the problem continues, it's worth checking a nearby cause rather than repeating the same steps. The guides below cover the most common related issues.
