HP deskjet 2540 would not scan

[Changhua]

Hello, 

I have a Dell PC laptop and HP2540 series Deskjet printer. It could print. But, when I try to scan, it says "Scanner communication cannot be established. I tried "HP Print & Scan Doctor 5.7.3,"  in the process, it made scanner to scan.  Then it says "Window Image Acquisition  error." The following items are checked with a green check mark:  Recommended Update,  Device Manager,  Driver Check, Device Status. Then it says "Some issues were found and fixed with your product,"  and the following items are also checked with a green check mark: Registry, HP Scan. Windows (WIN) Scan is the only item not checked with a green check mark. But, at the bottom it also says "Window San Issue Fixed." I clicked "Test Scan," it still says "Scanner communication cannot be established. "

Please help.

God bless you.

Changhua.

I found the solution to my problem.

By un-installing and re-installing printer driver, I was able to fix the problem and scan normally again.
