HP Photosmart M22 Digital Camera experienced an error

I was happy using my HP Photosmart M22 Digital Camera until yesterday when this message appeared on the LCD (see below). I tried turning it off then on but nothing happened to improve the status of my camera.
I am not a techie person so please teach and guide me how to reset the camera.
Thanks in advance.
