Abstract:
1. An apparatus for testing a cartridge in a printer for a defect wherein the printer has a port wherein the defect of the cartridge is identified by a yield test and a post test, the apparatus comprising: a housing having walls defining an interior wherein the housing has an exterior surface; a logical device within the interior of the housing wherein a power source supplies a voltage to the logical device wherein the logical device is programmed to instruct the printer to perform the yield test and the post test; a user interface located on the exterior surface of the housing wherein the user interface is connected to the logical device wherein the yield test or the post test is selected with the user interface and further wherein the logical device is programmed to produce a signal corresponding to the yield test and the post test; a connector on the exterior surface of the housing wherein the connector connects to the logical device wherein the logical device communicates with the printer via the connector and the port of the printer wherein the signal is transmitted from the logical device to the printer via the connector and the port of the printer and further wherein the cartridge prints a page of paper based on the signal from the logical device wherein the connector is a light emitting port that emits infrared light that transmits the signal from the logical device to the port of the printer; and a first light emitting diode on the exterior surface of the housing wherein the first light emitting diode emits light if the signal is transmitted from the logical device to the printer via the connector and the port of the printer.
