Remounting The EEPROM (IC3A)
Notes:
If the Imaging Cartridge is not to be replaced after the Master Board has been replaced with a new one,
be sure to remount the EEPROM (IC3A) from the old to new Master Board.
If the Master Board has been replaced with a new one and the EEPROM (IC3A) has not been
remounted, be sure to replace the Imaging Cartridge with a new one. Because the EEPROM contains
no data in this case, make settings and readjustments as necessary.
