Printer consumable having data storage for static and dynamic calibration data, and methods

摘要

Embodiments of the present invention include methods and apparatus for compensating for variations between different ink or toner characteristics, and for variations between sensors, by characterizing the ink or toner and storing one or more static threshold level on printer consumable memory devices during manufacture of the printer consumables. When installed in a printer, a dynamic threshold may be determined based on the static threshold level; the dynamic threshold accounting for variations between sensors and printers. The dynamic threshold may further be stored on the printer consumable memory device.
