My 7416cg worked fine with Win7 Prof but since installing Win7 home, Windows can't find drivers to instal the printer. Haven't found anything online. Any suggestions?

It's pretty old printer - newest drivers on manufacturer website are from 2005. Anyway you can try to install XP drivers - if you have Win7 Home 32bit, it might work:

I have the original CD with twain and print drivers for Win2k, Win9x, WinNT & WinXP, but Win7 won't use any of them. When I try to load using Add Printer, it says no valid driver found, and won't accept any of the .inf files on the CD.

Do you have 32bit or 64bit edition of Windows 7?

Also it is always better to download updated drivers from manufacturer website - sometimes they fix issues that appears on drivers on CD :)
