NOTE
▪ Never use the combination of the used EEPROM removed from another machine and the original MFP board. This combination
causes corruption of stored data.
Note that the combination of the original EEPROM and the used MFP board removed from another machine also causes the same
problem.
▪ Always replace the EEPROM/1 and EEPROM/2 as a set.
Replace them one at a time to prevent a mix-up between new and old and the device positions.
