scanner "not connected"

[ghjohnston]

My scanner has been working OK until this morning

I get a "scanner not connected" on my computer when I check through the downloaded Microsoft scanner app.

I also get a message on the scanner display "check the computer connection"

However, I can print the Windows print Test page when activated from my computer back to the scanner.

Checked and replaced the micro USB connection into the computer.

Turned the scanner off and on several times, also removed and replaced the connection cable from the computer to the scanner. ( and rebooted the computer)

My computer is a Dell Latitude laptop, less than 2 years old.  The HP Envy scanner is approximately 4 years old.

What else can I do to establish/confirm a connection between my scanner and computer?
