Having problem with my Mac 10.6.8 recognizing my HP printer for scanning

If you are using Snow Leopard and have HP software for pre-Snow Leopard (either from a CD not marked as compatible with 10.6 or you recently upgraded to Snow Leopard and had the HP software on your Mac before you upgraded - even if you did a standard uninstall of the old software or installed new software over the top of it) you must uninstall the software using the 'scrubber' option:

Go to Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Hold the Ctrl, Opt and Cmd keys and click on Uninstall <<<< Scrubber Option
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
Click Continue and let it finish

Restart your Mac

Now, run a Software Update.

Finally, download and install the "Full Featured" Driver and Software from the "Support & Drivers" link at the top of this page.

Thanks for the post. I did the uninstall and reinstall as you asked, but it did not work. If I try to scan from the printer it says there is no connection to the computer, and if I try from the computer (HP Scan Pro) it also fails. Is there an updated version for the installation to OS 10.6.8, as the installation CD that came with the printer says its for 10.4 and 10.5?

OK, I also did the Full Driver and software update that you suggested, that I missed until after the last post. The computer was restarted after the update.

The scan configuration has now changed on both the printer and computer, but they still don't recognize one another.

You cannot scan from the printer to the Mac, but try starting a scan on the Mac using the Image Capture app (its in your Applications folder).

Image Capture recognizes the printer/ scanner but it failed to start a scan session.

Is this a USB connection?  If so, make sure you are not going through a USB hub, plug directly into your Mac.

Let's reset the printing system:

- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

Still a no go after re-adding my printer .... attempt to open scanner session failed from both System Preferences (print and scan) and Image Capture. I'm thinking we have an incompatibility that won't be solved with this combination?

OK, time for the big guns.  Let's make sure your OS X is healthy:

1. Download and install Mac OS X 10.6.8 Update Combo.
2. Download and install HP Printer Drivers for Mac OS X v10.6 from Apple.

That did it! Scans work from both Image Capture and HP Scan Apps.

Thanks for sticking with me on this.
