Regarding the Service Life of Domino ITM Module Chips？

For the ITM02 chip, the service period begins the moment it is put into use; it has a validity of one year (e.g., May 30, 2025 – May 30, 2026).

For the ITM06 chip, the service period begins the moment it is put into use and lasts for 3,500 hours.

For the ITM03 chip, the service period begins the moment it is put into use and lasts for 2,000 hours, or is limited to a maximum duration of six months.

The 02 and 06 chips are designed for use with black ink systems, whereas the 03 chip is designed for use with white ink systems—hence its shorter service life.
