Abstract

Systems and methods for connector for supplying fluid to a print system. One system is an apparatus that includes a fluid supply station of a printer with a connector to couple with a fluid source for supplying fluid to at least one printhead of the printer. The connector includes an interface having a body with an end surface that corresponds with a face of a nozzle of the fluid source. The connector also includes an inlet protruding from the end surface and configured to enter an opening of the nozzle for receiving the fluid from the fluid source. The connector further includes communication circuitry disposed on the end surface and configured to establish a connection with corresponding communication circuitry disposed on the face of the nozzle of the fluid source when the inlet enters the opening of the nozzle and the end surface and the nozzle face align.

First claim

We claim:

1 . An apparatus comprising:
a fluid supply station of a printer comprising:
a connector configured to couple with a fluid source for supplying fluid to at least one printhead of the printer, the connector comprising:
an interface having a body with an end surface that corresponds with a face of a nozzle of the fluid source;
an inlet protruding from the end surface and configured to enter an opening of the nozzle for receiving the fluid from the fluid source; and
communication circuitry disposed on the end surface and configured to establish a connection with corresponding communication circuitry disposed on the face of the nozzle of the fluid source;

wherein the communication circuitry establishes the connection inside a seal that is formed when the fluid source couples with the connector; and wherein the seal prevents air from entering a flow of fluid from the fluid source to the connector.

2 . The apparatus of claim 1 further comprising:
a processor configured to analyze the connection, and to validate the fluid source based on the connection.

3 . The apparatus of claim 2 further comprising:
a blocking mechanism communicatively coupled to the processor and configured to move to a first position to prevent the interface from retracting into the connector, and to move to a second position to allow the interface to retract into the connector;
wherein, in response to a determination that the fluid source is valid, the processor is configured to direct the blocking mechanism to move to the second position to allow the interface to retract into the base of the connector so that the inlet contacts a valve in the nozzle and receives the fluid from the fluid source.

4 . The apparatus of claim 3 wherein:
when the blocking mechanism is in the first position:
the interface protrudes from a base of the connector in a forward horizontal direction;
the inlet protrudes from the end surface in the forward horizontal direction for a first length; and
the blocking mechanism is disposed in the base behind the interface to prevent the interface from retracting into the base along a path in a reverse horizontal direction.

5 . The apparatus of claim 4 wherein:
when the blocking mechanism is in the second position:
the interface is able to retract into the base in the reverse horizontal direction;
the inlet protrudes from the end surface in the forward horizontal direction for a second length that is longer than the first length by an amount that corresponds with an amount of retraction of the interface into the base; and
the blocking mechanism is positioned in a vertical direction away from the path to allow the interface to retract into the base in the reverse horizontal direction.

6 . The apparatus of claim 5 wherein:
the first length is shorter than a distance from an entrance of the opening in the nozzle to the valve in the nozzle operable to release the fluid from the fluid source such that when the inlet protrudes from the interface for the first length the inlet enters the nozzle but does not contact the valve to release the fluid; and
the second length exceeds the distance from the entrance of the opening of the nozzle to the valve in the nozzle such that when the inlet protrudes from the interface for the second length the inlet enters the nozzle and contacts the valve to cause the fluid to flow from the nozzle into the connector.

7 . (canceled)

8 . The apparatus of claim 1 wherein:
the communication circuitry comprises conductive material configured to establish an electrical connection with corresponding conductive material disposed on the face of the nozzle of the fluid source.

9 . The apparatus of claim 8 wherein:
the electrical connection is established when the inlet enters a spout and the end surface and the nozzle face align to cause the conductive material to contact the corresponding conductive material.

10 . The apparatus of claim 1 wherein:
the communication circuitry comprises a radio frequency identification (RFID) transceiver configured to establish a communication connection with a corresponding RFID tag disposed on the face of the nozzle of the fluid source.

11 . The apparatus of claim 10 further comprising:
the communication connection is established when the inlet enters the spout and the end surface and the nozzle face are within a threshold distance.

12 . A fluid connector comprising:
a tubular body configured to slide with respect to a fixed base; a blocking mechanism configured to move between a first position in the base behind the tubular body to prevent the tubular body from sliding, and a second position that allows the tubular body to slide into the base; an end on one side of the tubular body; an inlet extending from the end and configured to enter a nozzle of a fluid source for receiving fluid into the fluid connector; communication circuitry disposed on the end around the inlet and configured to connect to corresponding communication circuitry disposed on an opposing surface of the fluid source; and a processor coupled to the communication circuitry and configured to direct movement of the blocking mechanism based on the connection.

13 . The fluid connector of claim 12 further comprising:
the communication circuitry comprises conductive material disposed on the end of the tubular body and the corresponding communication circuitry comprises conductive material disposed on the opposing surface of the fluid source;
the communication circuitry and the corresponding communication circuitry are configured to contact to form the electrical connection when or after the fluid source couples to the fluid connector; and
the processor is configured to confirm coupling of the fluid source and fluid connector based on the electrical connection.

14 . The fluid connector of claim 13 wherein:
the fluid source is coupled to the fluid connector when an airtight seal is formed between the tubular body and the fluid source; and
the electrical connection between the electrical contacts and the electrical pads is formed on or inside the seal.

15 . The fluid connector of claim 12 wherein:
the communication circuitry comprises an radio frequency identification (RFID) transceiver disposed on the end of the tubular body and the corresponding communication circuitry comprises an RFID tag disposed on the opposing surface of the fluid source;
the communication circuitry and the corresponding communication circuitry are configured to establish a communication channel when or after the fluid source couples to the fluid connector; and
the processor is configured to confirm coupling of the fluid source and fluid connector based on the establishment of the communication channel.

16 . A system comprising:
a fluid source configured to dispense fluid, the fluid source including a nozzle, a valve configured to dispense the fluid from an opening in the nozzle, and first communication circuitry disposed on a face of the nozzle around the opening; and a connector that is configured to receive the dispensed fluid from the fluid source, the connector including a body with a coupling end configured to couple with the fluid source to form a seal, second communication circuitry disposed on the coupling end that correspond with the first communication circuitry on the face of the nozzle, and an inlet that protrudes from the connector and configured to receive the fluid from the opening of the nozzle; wherein the connector includes a processor configured to validate the fluid source in response to establish
