Abstract:
A supply item has toner for use in an imaging device. A chip has memory storing quanta indicating allowed usage of the supply item over its lifetime and a multiplier correlating the quanta to toner mass. The imaging device requires quanta to conduct imaging operations and loads the quanta and multiplier by way of a certificate stored in the memory. The imaging device retrieves quanta from the chip over time and both devices keep tally. Initialization between the supply item and imaging device includes providing encrypted and unencrypted instances of firmware versions and certificates from the supply item that the imaging device can compare for security. Alternatively, the supply item defines a fuser assembly, imaging unit, intermediate transfer member, or other component installed for use in the imaging device.

Claim (Index 4):
A supply item for installation in an imaging device having a master controller, comprising:\n a housing; and a chip connected to the housing and configured as a slave for I2C electrical communication with the master controller, the chip having a memory storing a certification having a total amount of quanta indicating allowed usage of the supply item over a lifetime thereof and a multiplier correlating the quanta to a metric related to the housing, wherein the memory further stores types of imaging devices suitable for use with the chip.
