Abstract

It is desirable to be able to identify specific characteristics of an ink tank fluidly connected to an ink jet printhead such as color, brand, etc. One method is to attach metal strips at strategic locations on the outside surface of the ink tank and sense the presence of the strips by inductive proximity switches. A variation is to use an analog inductive sensor and a range of different compositions for the metal strips.

It is desirable to be able to identify specific characteristics of an ink tank fluidly connected to an ink jet printhead such as color, brand, etc. One method is to attach metal strips at strategic locations on the outside surface of the ink tank and sense the presence of the strips by inductive proximity switches. A variation is to use an analog inductive sensor and a range of different compositions for the metal strips.

A second ink tank identification method is to place minute magnetic strips at strategic locations on the outside surface of the ink tank. The magnetic strips can be sensed by reed switches and, in turn, positively decoded.
