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.

Electrophotographic control in imaging devices, including sensing current between a developer roll and drum pertaining to current of a latent image and a paschen breakdown
An imaging device has a developer roll to provide toner to a photoconductive drum to develop a latent image on the drum for direct transfer to media or an intermediate transfer member. A power supply in communication with a controller sets relative voltages on the developer roll and drum. During transfer of the toner, the imaging device determines a current between the developer roll and drum. In turn, the controller determines a charge and mass of the toner for setting with the power supply an operating voltage on the drum or developer roll. Preventing and reporting toners with insufficient charge are other embodiments.

When a media tray is inserted into a printer with the leading edge of the printed page going into the printer first, multiple sheets of media may slide off the media stack (“shingle”) into the paper path if the primary input tray is inserted too aggressively. This may result in double feeds and/or paper jams for the user. Disclosed is a mechanism that is transparent to the user for slow speed tray insertions but provides force feedback to the user indicating tray insertion at too high of speed. If the user inserts the tray below the speed threshold, then the result is a normal tray insertion. If the user inserts the paper tray above the speed threshold, then there is a feedback to the user to slow the tray insertion to an acceptable velocity.

METHODS FOR RESTRICTING READ ACCESS TO SUPPLY CHIPS
An example method for restricting read access to content in the component circuitry and securing data in the supply item is disclosed. The method identifies the status of a read command, and depending upon whether the status disabled or enabled, either blocks the accessing of encrypted data stored in the supply chip or allows the accessing of the encrypted data stored in the supply chip.
