Dell V305V Wireless Printer/Scanner blinking power button

Hi im having a problem with a v305v printer...

Everythings connected fine and it worked well untill the drivers were installed and it started not working.

The problem is when i hit the power button it blinks green 2 times and shows a red exclamation mark on the panel..

So i took the printer apart to see if there were any bad connections and there weren't, does anyone know how to relieve this problem?

Thanks
