CONSUMABLE COMPONENTS FOR IMAGE FORMATION Russian patent published in 2019 - IPC G06F3/12 B41J2/175 

FIELD: physics.

SUBSTANCE: invention relates to consumable components for imaging. Consumable image forming component includes a first memory and a second memory, wherein the first memory stores an indication of at least one of unsigned data, signed data and limited data stored in the second memory, or absence of data in the second memory. When at least one of unsigned data and signed data are present in the second memory, the second memory stores control data of consumable components. When the consumable image forming component is connected to the printer and the consumable components control data are stored in the second memory, control data of the consumable components cause the printer to dynamically determine one of the output of the printed sheets during the service life, low filling or emptying of the consumable component for image formation.

EFFECT: technical result consists in providing protection from use in printer consumable components for generation, which are not allowed for use in this printer.
