Wireless Scan with Kodak 5250

[maxass]

I just got me a new Kodak ESP 5250 AiO wireless printer. I installed the printer without the Kodak software and it prints wireless just fine, but unfortunatelly I don't get the scan function to work. In my printer overview the thing is only listed as a printer - no scanning available. The manual has no instructions for a use without the Kodak software but I really don't want to use it.
Does anybody have a clue how I could get that thing to give me a scan without cables?

I'm only talking about wireless scanning here, being connected via USB scanning also works.
