ABSTRACT:
A handheld device for testing printer cartridges interfaces with a computer for processing of test results. 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. The device may obtain 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. The application may present a pass/fail indication to a user and tally the number of passed/failed cartridges. The device for testing printer cartridges may include a sensor for detecting cartridge information and a computer program for altering the cartridge identification.
