hello guys, I ask to a technician to update the firmwares on a MP 8001, and I forgot to tell him to see what PCB are set in ADF, and turn out he put the old firmware on a new PCB, now machine don't recognize the ADF and we have to fix it, I have another board with a intermitent problem and I want to take the part where firmware are instaled and change to this board with no defect but with old firmware, someone know where this PCB save the firmware data?Thanks for helping me, here in Brazil a new board costs a lot.
