"HP imaging device not found"

[Brian94582]

For the second or third time in the past 3 years, HP Scan Extended (which I use to get 2-sided scanning) fails with the above message. No software installs/uninstalls or updates took place. It just starts failing with the above message. And each time I've had to go through the whole process documented in this post from 13 years ago to get it working again.

2-4 hours of work, because it doesn't always work the first time I go through it.
