Abstract

An apparatus may include an electrical interface to access a memory. Based on data receivable from the memory, an actuator may allow fluid flow from a print fluid supply external to the apparatus to a print fluid reservoir of the apparatus.

First claim

What is claimed is:

1. An apparatus comprising:
an electrical interface to access a memory, the memory being external to the apparatus;
a print fluid reservoir;
a fluid conduit to connect the print fluid reservoir with a print fluid supply, the print fluid supply being external to the apparatus;
an actuator to selectively allow fluid flow through the fluid conduit from the print fluid supply; and
a controller coupled to the electrical interface, the controller to determine a print fluid quality based on data receivable from the memory via the electrical interface, and the controller to control the actuator based on the print fluid quality.

2. The apparatus of claim 1 , wherein the data receivable from the memory includes an identifier, and wherein the controller is to access a data store based on the identifier, the data store including information regarding a use of the print fluid supply.

3. The apparatus of claim 2 , wherein the data store is accessible by the controller via a network interface connector.

4. The apparatus of claim 1 , wherein the data receivable from the memory includes an indication of an amount of print fluid in the print fluid supply.

5. The apparatus of claim 4 , wherein the controller is to cause a time of an access to the print fluid reservoir to be stored in the memory.

6. An apparatus comprising:
a print fluid reservoir;
a print fluid input port to receive print fluid from a print fluid supply, the print fluid supply being external to the apparatus;
a pump coupled to the print fluid reservoir and the print fluid input port, the pump to pump print fluid from the print fluid supply into the print fluid reservoir;
an interface to access a memory, the memory being external to the apparatus and coupled to the print fluid supply; and
a controller to determine a print fluid quality based on data receivable from the memory via the interface, and the controller to control the pump.

7. The apparatus of claim 6 , wherein the controller is to control the pump based on the print fluid quality.

8. The apparatus of claim 7 , wherein the controller is to control the pump based on a status of the print fluid reservoir.

9. The apparatus of claim 6 , wherein the controller is to receive an override command and control the pump based on the override command.

10. The apparatus of claim 9 , wherein the controller is to store data in an event log based on the override command.

11. A method comprising:
detecting a presence of a print fluid supply at a print fluid input port of a printer;
reading print fluid data from a memory, the memory coupled to the print fluid supply; and
based on the print fluid data, pumping print fluid from the print fluid supply through the print fluid input port and into a print fluid reservoir of the printer.

12. The method of claim 11 , wherein the detecting includes the printer reading data from the memory via an electrical interface.

13. The method of claim 11 comprising:
determining a print fluid quality of the print fluid based on the print fluid data; and
providing a warning based on the print fluid quality.

14. The method of claim 13 comprising storing a value for the print fluid quality and storing an association between the value and the printer.

15. The method of claim 11 comprising writing data into the memory, the data including a quantity of print fluid pumped from the print fluid supply and a time the pumping occurred.
