Hp OfficeJet d145 "LED lights flash" Message repeats "Turn Power off and on"

My Hp OfficeJet d145 starts a self test but within a second or two all led's flash rapidly and "Turn power off and on" repeats in message window.  A simi-full reset didn't help.  Unit & ADF have been checked for jams and the ADF unplugged. Input voltage is normal and a 2nd external power supply tried.  I have tried the reset where power is applied and removed 3 times at 30 second intervals.  This allowed the d145 to complete its self test but problem returned as soon as the copy button was pressed.  Any ideas?  Thanks
