The return arrow, the question mark, the red x and the center white light are all blinking rapidly

[Skromfols]

My HP Smart Tank 7602 has flashing symbols (return key, question mark and red X in a circle) and the center thin white light is also flashing rapidly.  This has happend 4 or 5 times and the only way I can get them to stop is to unplug the printer and then plug it back in.  When I do so it will work properly for a day or so, then go back to flashing.
