15. TROUBLESHOOTING OF i-Option
15.1 Structure of license management
• The functions available with i-Option can be activated by entering "License code" to the main body.
• License code is issued and controlled by License Management System (LMS).
To prevent unauthorized use of the license code, each main body is identified individually so that the license code cannot be activated
unless it matches with the authorized the main body.
15.2 License management information
• Since license code needs to identify each main body, it is issued using the serial number of main body and "unique value" that is generated
inside the main body.
• The "unique value" is stored to the memory region on the MFP board and at the same time some parts of it are memorized by eMMC board
and EEPROM. The activated function cannot be used unless the both figures conform.
Since these figures are out of target of [Memory Data Backup], when any trouble occurs at either nonvolatile memory, "License
Management Error" is generated due to discordance of the figures.
15.3 Error message
