"not working" is not enough information.
Doesn't run?
Isn't on the PC?
Runs but doesn't connect?
Error message at the moment it "doesn't work"?
Have you simply removed it, rebooted the PC and reinstalled it?
It's been 7 years since any drivers were developed for this printer, so it is safe to say it is no longer supported or developed for, if Windows 10 has an update that thoroughly kills it's software you may need to roll back to Version 1511 of Windows 10 (Pre Version 1607 "Anniversary" edition), Upgrade the printer or scan to a shared drive on the Windows 7 PC, and map the share to the Windows 10 PC so both PC's can grab the scans.
