ABSTRACT:
A handheld device for testing printer cartridges that interfaces with a computer for processing of test results is provided. Multiple testing devices may be coupled to the computer. In one embodiment, each testing device includes a base board and an adaptor board. The base board includes a host processor and a computer interface. The adaptor board comprises a cartridge-specific socket for retaining a printer cartridge to be tested and test circuitry. The adaptor boards may be interchanged. In another embodiment, the device obtains power from the computer interface. A computer program communicates with the test device and displays the results of the tests through execution of a suitable application or program. In a presently preferred embodiment, the application presents a pass/fail indication to a user and tallies the number of passed/failed cartridges.
