Method and device for filling a printing-fluid container

A method of filling a printing-fluid container, the method comprising:

• providing a printing-fluid container that includes a first fluidic interface, a second fluidic interface, and a keying pocket having at least one distinguishing characteristic used to indicate a type of printing fluid, wherein the printing-fluid container further includes a reservoir configured to hold a free-volume of printing fluid and air mixed together, wherein each of the first fluidic interface and the second fluidic interface extends into the reservoir, and wherein the printing-fluid container includes, while being filled, a substantially vertical leading surface having a downwardly-extending protrusion, and wherein the first fluidic interface is positioned on the leading surface adjacent the downwardly-extending protrusion and the second fluidic interface is vertically aligned above the first fluidic interface on the leading surface, an alignment pocket recessed from the leading surface, and an electrical interface on the leading surface, the electrical interface being in electrical communication with a memory, and;
• identifying the type of printing fluid indicated by the characteristic of the keying pocket;
• and
• passing printing fluid of the identified type through the first fluidic interface into the printing-fluid container.

A method of filling a printing-fluid container, comprising:

• providing a printing-fluid container that includes a substantially planar leading surface having an outer-perimeter with a top edge, a first lateral edge, a second lateral edge, and a bottom edge that includes a downwardly-extending protrusion, wherein the printing-fluid container includes a printing-fluid interface on the leading surface adjacent the downwardly-extending protrusion, an air-interface located on the leading surface proximate the top edge in vertical alignment with the printing-fluid interface, an alignment pocket recessed from the leading surface substantially equidistant between the printing-fluid interface and the air-interface, an electrical interface in electrical communication with a memory and located on the leading surface between the alignment pocket and the first lateral edge, and a keying pocket having at least one distinguishing characteristic used to indicate a type of printing fluid, the keying pocket being recessed from the leading surface and located between the alignment pocket and the second lateral edge, and wherein the printing-fluid container provides a reservoir configured to hold a free-volume of printing fluid and air mixed together and wherein the printing-fluid interface and air-interface extend into the reservoir;
• identifying the type of printing fluid indicated by the characteristic of the keying pocket;
• and
• passing printing fluid of the identified type through the printing-fluid interface into the printing-fluid container.

A method of filling a printing-fluid container, comprising:

• providing a printing-fluid container that includes, while being filled, a substantially planar and substantially vertical leading surface, wherein the printing-fluid container includes a first fluidic interface on the leading surface and a second fluidic interface on the leading surface and above the first fluidic interface, and an alignment pocket recessed from the leading surface in a position between the first fluidic interface and the second fluidic interface, wherein the printing-fluid container further includes a reservoir configured to hold a free-volume of printing fluid and air mixed together and wherein each of the first fluidic interface and the second fluidic interface extends into the reservoir, an electrical interface on the leading surface, the electrical interface being in electrical communication with a memory, and a keying pocket having at least one distinguishing characteristic used to indicate a type of printing fluid, the keying pocket being recessed from the leading surface;
• identifying the type of printing fluid indicated by the characteristic of the keying pocket;
• passing printing fluid through the first fluidic interface into the printing-fluid container;
• and
• permitting air to pass through the second fluidic interface out of the printing-fluid container.
