Symptoms
- Scanning software doesn't list the printer/scanner as an option
- Error message says 'No scanner found' or similar
- Printing works fine but scanning doesn't
- Scanner worked before but stopped after an update
Likely causes
- CommonScanner driver or software not installedScanning often needs its own driver component separate from the print driver.
- CommonPrinter not connected properly (Wi-Fi, USB, or network)If the base connection is unstable, scanning specifically can fail even if printing still works.
- CommonWrong scanning app selectedWindows Fax and Scan, the manufacturer's app, and third-party software can each behave differently, and one may not see the device while another does.
- PossibleScanner service or feature disabled on the printerSome network printers need 'Scan to Computer' or a similar feature explicitly enabled.
What to do
- Confirm the printer is properly connected to Wi-Fi or USB and shows as online in the printer's device list.
- Reinstall the full driver package (not just 'print driver') from the manufacturer's website, which usually includes scan components.
- Try the manufacturer's dedicated scanning app instead of a generic OS scanning tool, or vice versa.
- On the printer's own control panel, check for a 'Scan to Computer' or 'Enable Scan' setting and turn it on if present.
- Restart both the printer and computer after reinstalling drivers.
- If using USB, try a different cable and port; if using Wi-Fi, confirm both devices are on the same network.
- Check Windows Device Manager or Mac's printer/scanner list to confirm the scanner component specifically is listed, not just the printer.
Tools and parts
- None
When to call a pro
If the scanner still isn't detected after a full driver reinstall and confirming the connection, and printing works fine, the scanner module itself may have a hardware fault needing professional service.
