Note
After the Engine Control Board is replaced, NVRAM data saved prior to
replacement must be restored to the new board. Use the Service Diagnostic
NVRAM Access/MCU NVRAM Restore function to restore the data.
Detailed information is provided in "Service Diagnostic Tests" on page 3-9.
If the printer was previously not functional, or optionally even if it was,
move the NVRAM from the old board over to the new board.
