Laserjet Pro MFP M148fdw not scanning

[M378]

Printer working perfectly until connected to a brand new HP desktop with Windows 11.  Now printer works but scanner does not.  Message says it is not detected but once again printer function works perfectly.  I have reinstalled drivers multiple times and tried both usb and wireless connection.  I need this scanner to work.  Any suggestions?

Hello @M378 ,

The HP software must be completely uninstalled and removed of the system.

Then proceed as follows:

Check the system for

disable them, better uninstall them. Next...

Via USB, means wait until the installation asks to connect the printer/scanner.

Important information:

Change back the File Explorer settings -
