Replenishment system for a print media processor

A system for supplying a processing solution to a printing device comprising:

• a. a supply tank adapted to hold the processing solution;
• b. a printing device adapted to print images;
• c. a delivery system connected between the supply tank and the printing device, wherein the delivery system comprises
• i. a retaining vessel adapted to hold a retained fluid;
• ii. an adjustable liquid level probe set at a first specific depth in the retaining vessel and adapted to sense a predetermined amount of the retained fluid in the retaining vessel;
• and
• iii. a reference probe set at a second specific depth in the retaining vessel and adapted to provide a reference probe signal to the adjustable liquid level probe;
• d. a controller adapted to receive the adjustable liquid level probe signal from the adjustable liquid level probe which compares the adjustable liquid level probe signal against a preset reference, and when the signal from the adjustable liquid level probe equals the preset reference transmits a signal;
• e. a three-way valve adapted to receive the signal transmitted from the controller and move to permit a predetermined volume of the retained fluid from the retaining vessel to flow to the printing device or flowing an identical defined volume of the processing solution from the supply tank to the retaining vessel.

A method for supplying processing solution to a printing device, wherein the method comprises the steps of:

• a. providing a signal from a printing device that indicates a need for fluid;
• b. supplying a signal to a three-way valve to allow a predetermined amount of retained fluid from a retaining vessel to flow to the printing device;
• c. sending a signal to the three way valve to refill the retaining vessel with an amount of replenishment fluid identical to the predetermined amount of retained fluid from the retaining vessel;
• d. sending a signal from an adjustable liquid level probe to the three way valve to close the three-way valve.
