I've downloaded the full software installation kit from HP and installed it in my laptop running windows 7 OS. The printer was successfully installed and the scanner seems ok. When I try to use the scan feature the Photo smart essentials opened and ask me where to send the pix / docs that i am about to scan. When I hit the scan button the scanner has no reply, there is no error message that displayed too. Please help I've been trying to fixed this error for weeks now.
