Digital BW, The Print

OK, I've got flashing panel lights, all of 'em at once.  Turning off 
the printer for a while and disconnecting the computer don't 
seem to make any difference.

I had just run a series of head cleanings, with cleaning carts 
inserted, preliminary to inserting MIS FS carts.  When the flush 
image printed blank, I put in the MIS carts and right away the 
lights lit up.  At this point, the 3000 doesn't respond to the reset 
button or the hex dump command and doesn't seem to care if 
the carts are in or out.

Anybody run into this before?  I am hoping for a secret reset 
button somewhere and trying not to think of the possibility that it 
needs a new logic board.
