Hello sir.

After the Windows 11 update, it is a known issue that the scanner is no longer working.This issue is mainly due to a faulty eSCL protocol in Windows 11, version 24H2, which prevents the device from switching from eSCL mode to USB mode when needed, causing connectivity issues. Microsoft has addressed this issue with Windows Update (KB5048667) and later released on December 10, 2024.

You can try following these steps:

Make sure that your computer has the latest Windows update, which is KB5048667 or later. This can be done through the Windows Update feature.

If you've already installed the latest update and the problem persists, here are some things you can try:

Restart your computer, check that the printer driver is up to date, and if not, update the printer driver.

If your printer supports the eSCL protocol, make sure that the printer is set up correctly and that it is able to switch from eSCL mode to USB mode correctly.

Check and restart the Print Spooler service. Manually add the printer again after removing it, making sure to replace the current driver.

I hope this information helps.
