WINDOWS HOME 11 conflict with CANON MF SCAN UTILITY

Thanks for sharing the details! Recent Windows 11 builds silently prefer eSCL (AirScan) over WIA, and Canon MF scanners often fail under eSCL even though they still print.

Step 1 - Disable eSCL (AirScan) for the Canon scanner

This does not break printing.

Press Win + R

Type:

services.msc

Find Windows Image Acquisition (WIA)

Make sure:

• Startup type = Automatic
• Service status = Running

If WIA is not running, MF Scan Utility will NEVER work.

Step 2 - Remove the AirScan device (critical)

Open Settings → Bluetooth & devices → Printers & scanners

Click your Canon MF printer

Look for two scanner entries

• One says AirScan / eSCL
• One says Canon WIA

Remove ONLY the AirScan / eSCL scanner

• Do NOT remove the printer
• Do NOT remove the Canon WIA entry

Restart the PC.

Step 3 - Lock Windows to WIA (registry fix)

This prevents Windows from re-adding the broken AirScan scanner.

Press Win + R

Type:

regedit

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\stisvc

Right-click → New → DWORD (32-bit)

Name it: EnableESCL

Set value to 0.

Restart Windows

Step 4 - Rebind MF Scan Utility manually

• Open MF Scan Utility
• Click Settings
• Choose:
  Scanner: Canon MF (WIA)
  NOT AirScan
  NOT eSCL

Save and test scan.

See if this helps. If you need further assistance just let me know.

Best regards,
