Scanner says "no Computer found"

I am running on OS X, 10.9.2 version. I am using an HP 5520 and a wrieless connection via router C1000A

On the printer I toch the advance button and then the scan icon. I then touch the computer icon, wnating the scanner to scan to the computer. The message I get is "no computer found". I am having no problem printing, only scanning. Any help will be appreciated.
