ABSTRACT:
The system for a printer in its reservoir for consumables for office equipment includes essential command unit for a printer, an electric chip having a balance of consumables and memory and a device to control the reservoir of consumables. The device includes a chip/central unit interfaced in a computer intended to determine the content of the reservoir of consumables, by calculating the flow, in cooperation with the central unit, by estimating the quantity of consumables used according to the estimated quantity of printed copies, and the balance of consumables left. This system has applications to photocopiers as well.
