Hp j64350 Win7, Can't scan over LAN. It prints OK over LAN..

[into]

I have a hp J6450 printer which I need to scan over a LAN cable. I have setup static IP address on both the Laptop ASUS and the printer and have a direct connect LAN cable attached.. I have it installed and it prints fine over the LAN cable. But I can't scan over the LAN cable.. Once I connect up a USB cable between the two I can scan.. I need it scanning over the LAN. When I hit the scan button on the printer it does not "see" the laptop.. Solution center tells me that the install was incomplete.

Any help you can give me would be great.. I read a forum post and it suggest to click on the printer icon in the desktop, but I don't have one.. The printer shows up in the printer list and I can make it default and as I said print with it.. I am using windows 7.

Just for clarification, are you connecting the LAN cable directly to the computer from the printer, or is there a router in between the two?

Thank you for spending time to looking into my problem.

I am not using a router. The printer and laptop are connected directly to each to other, with static ip addresses, gateway and are on the same subnet. I know the network is working as I am able to print over the lan and I can ping the printer from the laptop over the lan.. I also disabled the wireless and had no USB connected and it printed. So I know the LAN is working fine and that I have the correct cable between the printer and laptop..

When I double click on the printer icon, there is no option for Scanning.  When I installed the printer again with the USB connected it all worked fine and shows a Scan option, but only over the USB. When I unplug the USB the printer goes off line. It looks like HP does not allow a printer over LAN to Scan. 

Any ideas or solution would be helpful.

From what it sounds like, you're using the wrong kind of cable.  If you have the printer can computer connected directly with the LAN cable and there is no switch, router, or network trafficking device in the connection, then you are creating a wired AdHoc connection, and need what is know as a crossover cable to allow the two-way communication that is required for scanning.  A standard LAN cable will only allow you to print, because it can't support the amount of two-way communication that's required.  Let me know if I'm interrupting your setup wrong, because there are things that can interfere with a standard network connection, but if you're AdHoc, you got to have the crossover cable.
