Supply Life Counters
Internal counters track the usage of the Consumables and Routine Maintenance Items
and store the values in NVRAM. The image processor board monitors these counters
in order to display the near end-of-life and end-of-life messages.
Print life ratings are based on 5% coverage and an average job length of 4 pages.
