C4780 Prints but will not scan or copy

My new C4780 prints fine, but I can not get it to scan or copy. I am using 10.6.3 (Snow Leopard) on my computer. Originally, I installed the CD that came with the computer. After reading some of the postings, I uninstalled the HP software. When I attempt to scan using Preview or Image Capture, I get the same message, "Failed to open a session on the device."  The screen on my scanner then reads, "Scan failure - Unable to copy or scan."

 

When I attempt to simply copy an item on my machine, I get the same message, "Scan failure - Unable to copy or scan."

 

Can someone help>

Re: C4780 Prints but will not scan or copy

since it's happening by itself, check out this list of things to try  (here)

 

I've heard that step four can often help.

 

Once it copies without the Mac connection, it may very well work with the build-in scan support in 10.6 (preview/image capture, as you noted...)

 

Hope this helps.
