officejet 6950
macOS 10.15 Catalina

In common with other users I a getting an error message about 30 mins after I switch on.  It continually flashes.  The code is OXB8519CA6.  Others have reported the same or similar codes.  I can clear it by pressing the power button and then I am OK for about 30 mins. I have reset the printer both by disconnecting and reconnecting the power and from within MAC settings.  I have reset the network.  None of this works 

 

My firmware is up to date and I wonder if the recent update has caused the problem.

 

Any ideas?
