HP Deskjet F4180 won't scan on my mac

IVE GOT THE SAME PROB! I think HP doesnt have a driver yet for Leopard..

Hello,
Here's what I did to get it to work:
1. I ran the HP uninstaller and removed everything. 2. I downloaded the drivers [full set, with apps] from HP and installed them. 3. I think this was the trick - Open the HP Device Manager and click Scan Preferences in the drop down menu next to Information and Settings. Click the settings tab and make sure only ONE option has the "skip scan preview window' option checked. I picked Front Panel.
Could be coincidence but it worked for me. :D Good Luck.

Thanks, This works.
If you are having this problem, don't contact HP, they will keep you on the phone forever getting your info, and in the end, say they can't help you unless you pay for tech support.

I had exactly the same problem, literally everything you described and now my printing scanning and all other functions work perfectly again. This is what I did-
uninstall everything HP related with the HP uninstaller program

 and download the whole installation file (~180M) Run the installation and the printer was now recognised and all programs work. It did not work when I tried installing off the disk like you said you were having problems with too.
