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 16):
A method of setting up electrical communications between an imaging device and a supply item configured for installation in the imaging device, the imaging device having a controller and the supply item having a chip configured to electrically communicate therewith, the chip of the supply item having a memory storing a device certificate identifying the chip, comprising enabling the chip of supply item to provide to the imaging device both an unencrypted and encrypted instance of the device certificate.
