AR-M550/M620  ROM VERSION-UP METHOD  10 - 5
5. Turning OFF the power during the 
version-up procedure
If the power is turned OFF during the version-up procedure, normal
writing of data cannot be assured even though the machine can be
booted again.
In such a case, use the spare PCU PWB ROM, the MFP control PWB
ROM (boot, program), and the scanner control PWB ROM each of
which includes the program to be operated, and perform the version-
up procedure again.
Replace with the spare PCU, the controller boot, the scanner control
PWB ROM, and perform procedure “4.” for the replaced ROM again to
write data into it.
