Abstract
Ink port adapters for multi-color inkjet heads. In one embodiment, the ink port adapter includes two hose fittings for connecting to hoses, and four openings that align with four ink ports of a four-color inkjet head. The adapter includes one ink path that connects one of the hose fittings to two of the openings, and another ink path that connects the other hose fitting to the other two openings. The adapter therefore converts the four-color inkjet head into a two-color inkjet head.

An apparatus comprising:
- an ink port adapter that converts a two-color inkjet head to operate as a single-color inkjet head;
- wherein the two-color inkjet head includes a nozzle surface with a row of nozzles, and includes an Input/Output (I/O) side opposite the nozzle surface;
- wherein the I/O side has two ends each having two ink ports for receiving ink from an ink supply;
- the ink port adapter comprises:
- a body having a first surface and a second surface;
- a hose fitting that extends from the first surface of the body for connecting to a hose;
- two openings on the second surface of the body;
- an ink path through the body that connects the hose fitting to each of the openings;
- and
- connecting holes that pass from the first surface to the second surface to align with threaded holes on a first end of the two-color inkjet head so that the two openings on the second surface of the body align with two ink ports on the first end of the two-color inkjet head.
