Canon G3070 printer - unable to scan

Try these steps to get the Canon G3070 scanner working in Windows 11:

1. Verify Windows detects the scanner
   1. Turn the printer/scanner on and connect it to the PC (USB or Wi‑Fi as appropriate).
   2. Select Start > Settings > Devices > Printers & scanners (or use the shortcut: ms-settings:printers).
   3. In Printers & scanners, confirm the Canon G3070 is listed.
   4. If it is a multifunction device, select it, choose Manage, and check the drop‑down list for an entry that starts with Scanner: to confirm Windows sees the scanner part.
   If the device is missing or the scanner entry does not appear, remove the printer (if present), then reinstall it using Canon’s full driver/software package for Windows 11 from Canon’s support site.
2. Reinstall or update Canon software/drivers
   1. Uninstall any existing Canon G3070 software from Settings > Apps.
   2. Download and install the latest full driver and scanning utility for the Canon G3070 from Canon’s official support page (search the web for “Canon G3070 driver Windows 11”).
   3. After installation, restart the PC and test scanning again using Canon’s own scan utility.
3. Test with Windows built‑in scan tools Once the scanner is detected in Printers & scanners:
   • Use Windows Fax and Scan or the Scan feature in Windows to test scanning.
   • If scanning works in Windows tools but not in Canon’s app, the issue is likely with the Canon application; reinstall or contact Canon support.
4. If the scanner still does not work
   • Power‑cycle the printer and the PC.
   • Try a different USB port or cable (for USB connection).
   • If none of the above resolves the issue, contact Canon support for model‑specific troubleshooting.

If problems persist with Windows recognizing the device or scanning in general, also consider submitting feedback via Feedback Hub so Microsoft can collect diagnostic data.
