L1800 - all ok, but not printing

[The Hat]

CUANDO SE QUEMA LA PLACA PRINCIPAL Y TE IMPRIME EN BLACO SOLO REEMPLAZA EL FUSIBLE DE PROTECCION ES EL QUE SE VUELA CUANDO EL CABEZAL ESTA DEFECTUOSO....
REEMPLAZA EL FUSIBLE
Y ASEGURATE DE COLOCAR UN CABEZAL NUEVO

Thanks ISF. I have changed 4 print heads, 6 main boards, 2 power boards, & 3 main board to printhead cables, 3 computers (Acer, iMac, MacBookPro) 3 software downloads.

Still performing 'apparently' properly - but absolutely no ink printed on Nozzle Check, or general printing.

It is as if the whole system has been switched off, somehow?

I have a feeling its going to be embarrassingly simple - if and when we ever find a solution. ;-) ;-(
