Abstract
An example device capable of predicting print substance end-of-life (EOL) comprises a container to hold a print substance, the container comprising a refill port through which print substance is to be introduced into the container. The example device also comprises a processor to receive signals indicative of an amount of print substance introduced via the refill port. The processor is also to predict a print substance end-of-life (EOL) based on the amount of print substance introduced.
Claims20
A device comprising:
- a processor;
- a print substance applicator;
- a container to contain print substance, the container including a refill port;
- and
- a refill interface connected to the refill port, the refill interface to:
- connect to a refill container to receive print substance from the refill container;
- interact with an identification feature of the refill container, the identification feature indicating an amount of print substance received;
- and
- provide a signal indicating the amount of print substance received from the refill container to the processor,
- wherein the processor is to predict a print substance end-of-life (EOL) based on the provided signal.
A print device comprising:
- a refill interface to interact with an identification feature of a refill container and to receive a print substance from the refill container;
- a container to hold the print substance, wherein the container comprises an input port connected to the refill interface;
- and
- a processor to:
- receive a first signal from the refill interface to enable authentication of the print substance introduced to the container via the refill interface;
- receive a second signal from the refill interface indicative of an amount of the authenticated print substance introduced via the refill interface;
- and
- determine, based on the received second signal, a number of pages printable by the print substance in the container,
- wherein the first signal and the second signal are provided by the refill interface based on the interaction with the identification feature of the refill container.
A non-volatile computer readable memory having stored thereon instructions to predict a print substance end-of-life (EOL) based on an amount of print substance received by a print device from a refill container, the non-volatile computer readable memory comprising:
- instructions to determine whether a first signal received from a refill interface of the print device indicates that the received print substance comprises an authenticated print substance, the first signal based on an interaction of the refill interface with an identification feature of the refill container:
- instructions to, in response to a determination that the received print substance comprises the authenticated print substance, determine the amount of the print substance received based a second signal received from the refill interface, the second signal based on the interaction of the refill interface with the identification feature of the refill container;
- and
- instructions to determine a number of pages printable based on the determined amount of the print substance received.
