Answer 1

Dear James Frazier, 

Thank you for your question and for sharing the details into Microsoft Q&A Forum. 

I understand it's frustrating when printing works but scanning reports “scanner not connected.” At this point, I recommend that you review and try the steps provided in the Independent Advisor’s answer on your thread. That reply already covered restarting WIA and reinstalling Canon’s driver/Scan Utility. To help narrow this down, could you please share a bit more detail:  

• How is the MG3620 connected, USB or Wi‑Fi? 
• If it’s Wi‑Fi, are your PC and printer on the same network/SSID, and is any VPN or third‑party firewall running when the error appears? 
• When you open IJ Scan Utility, do you see the MG3600 series listed, and does it return any specific error code? 
• Have you had a chance to try scanning from a different computer? 

In the meantime, here are additional steps that you can try: 

1. Verify Windows-side discovery & apps 

• Test with the Windows Scan app (from Microsoft Store). If it won’t detect the scanner, go to Settings > Apps > Installed apps > Scan > Advanced options > Repair, and if needed Reset; then test again.  
• Ensure Windows is up to date (Settings > Windows Update > Check for updates).  

2. If you use Wi‑Fi with the MG3620 

• Same network & no VPN: Confirm the PC and printer are on the same SSID, temporarily disconnect VPN, and (if you use a third‑party firewall) allow the installer/Scan Utility during discovery.  
• WSD scan switch: On models that support WSD scan, make sure WSD Scan is enabled on the device and then re‑add the device from Control Panel > Devices and Printers > Add a device.  
• Background info: Windows uses a WSD/WIA class driver for network scanners; ensuring the device is reachable on the LAN is key to scanning. 

3. If you use USB 

• Cable/port sanity checks: Connect the printer directly to a USB port on the PC (avoid hubs), try a different port/cable, then test from IJ Scan Utility. If issues persist, a temporary switch to wired/wireless LAN can be a useful step.  
• Driver binding check (avoid “IPP Class Driver”): If Windows silently attached a generic Microsoft IPP Class Driver instead of Canon’s driver, scanning could fail while printing still works. Open Control Panel > Devices and Printers > (your Canon) > Printer properties > Advanced and verify the Driver isn’t listed as “Microsoft IPP Class Driver.” If it is, remove the device and reinstall using Canon’s package so it binds to Canon’s driver.  

While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding. 

I hope these checks help you restore scanning on your Canon PIXMA MG3620 in Windows 11, whether you’re connected by USB or Wi‑Fi and minimize further interruptions. Wishing you a smooth, consistent experience with both printing and scanning going forward.

Hi,

I suggest going to Services and restarting the Windows Image Acquisition (WIA) service. This restarts the Windows service responsible for detecting scanners.

• Press Windows + R > Type services.msc and press Enter.
• Find Windows Image Acquisition (WIA).
• Right-click it and click Restart.

If the issue persists, go to the printer manufacturer’s website and download the latest driver available for your printer.

• Go to the Canon support page.
• Download the MP Driver / Scan Utility (IJ Scan Utility) for Windows.
• Uninstall the current Canon printer from Settings > Bluetooth & devices > Printers & scanners.
• Restart your computer.
• Install the downloaded Canon driver and scan utility, then add the printer again.
