Abstract
One method of ink formulation may include providing a shipping material in a reservoir of a printing mechanism, placing a concentrated ink in communication with the reservoir, and mixing the shipping material and the concentrated ink together to create a print-ready ink.
Claims7
A method of ink formulation, comprising:
- providing a shipping material, separate from a concentrated ink, in a reservoir of a printhead assembly, said reservoir directly connected to a printhead of said printhead assembly;
- after placing said shipping material in said reservoir, placing a concentrated ink in communication with said reservoir;
- and
- mixing said shipping material and said concentrated ink together to create a print-ready ink, wherein said mixing further comprises pumping said concentrated ink into said reservoir.

A method of ink formulation, comprising:
- providing a shipping material, separate from a concentrated ink, in a reservoir of a printhead assembly, said reservoir directly connected to a printhead of said printhead assembly;
- after placing said shipping material in said reservoir, placing a concentrated ink in communication with said reservoir;
- and
- mixing said shipping material and said concentrated ink together to create a print-ready ink, wherein said placing a concentrated ink in communication with said reservoir comprises providing a concentrated ink cartridge in communication with said reservoir, and wherein said mixing comprises pumping said concentrated ink and said shipping material at least two times between said reservoir and said concentrated ink cartridge.

A method of initializing a printing mechanism, comprising:
- placing a diluent, in an absence of colorant, in a reservoir of a printing mechanism, said reservoir directly connected to a printhead of said printing mechanism, said diluent being less susceptible to evaporation than a print-ready ink;
- and
- upon a first start-up of said printing mechanism, adding a colorant to said diluent to create a print-ready ink.
A printing mechanism, comprising:
- a printhead;
- a first reservoir directly connected to said printhead and initially containing only a shipping material therein;
- and
- a second reservoir adapted to be operatively connected to said first reservoir and containing a concentrated ink therein,
- wherein said printing mechanism further comprising a pump and a valve each positioned along a connection line connecting said first and second reservoirs.

A printing mechanism, comprising:
- means for printing an image;
- means for holding a shipping material therein, separate from a concentrated ink, said means for holding a shipping material being directly connected to said means for printing;
- and
- means for holding a concentrated ink therein, said means for holding a concentrated ink being connected to and being adapted for supplying concentrated ink to said means for holding a shipping material,
- wherein said printing mechanism further comprising means for pumping connected between said means for holding a shipping material and said means for holding a concentrated ink.
