4.2.5 Life Counter Read/Write

You can read the life counter data from the MCU PWB EEPROM (NVM)
or write the data in the EEPROM (NVM) using the Parameter Control
commands/status.
NOTE: Before you replace the MCU PWB, do the following:
(1) Read the data from the life counters in the MCU PWB before
replacement.
(2) Replace the MCU PWB.
(3) Write the life counter data in the MCU PWB after
replacement.
NOTE: If you cannot read the data from the new MCU PWB after
replacement, write an expected value (estimated from future
usage conditions) in the MCU PWB.
NOTE: If you replace a regularly replaced part (in the MAIN FUSER
ASSEMBLY or 2nd BTR ASSEMBLY) or DRUM CARTRIDGE
(without CRUM function specifications) with a new one, write "0"
in V1 through V4.
NOTE: You can do the same in the EEPROM Read/Write function
described in Section 4.2.6 "Executing Diagnostics". If you run
the EEPROM Read/Write function after replacing the MCU
PWB, you do not need to read/write the life counter data using
the Parameter Control function.
NOTE: You can use the Parameter Control commands and status to
read/write the setting values in the registrations.
