Hello guys,
Please let me share this to you (could be also this issue somehow…)
I faced also this unpleasant issue couple weeks ago: all my Cetus being not connected, not responding…
Guess what: this occurred just after a wonderful Windows 10 upgrades!
Issue was this: Cetus driver was locked because declared as “unsigned/unverified” by “windows 10 updated version”.
So I had to make some modification into Windows 10 boot up configuration…
Have a look into this link:
Then guess what? No more issue…Printers all connected and fully functional…
Hope it could help…otherwise, keep this hypothesis in mind…
Best regards!
