Abstract: The invention is a replacement printed circuit board or chip that allows a printer to utilize a replacement printer cartridge. The printed circuit board has an encrypted memory device and a microcontroller, wherein the microcontroller is programmed to intercept the request from the printer for the unique lot number data and to provide the appropriate unique lot number data to the printer in response to the request. The encrypted memory device is programmed just like the custom original equipment manufacturer encrypted memory device, and, with the exception of providing the unique lot number data to the printer, communicates with the printer just as the original equipment manufacturer encrypted memory device would.

Abstract: The present invention is a circuit board with precision clearance holes that accommodate components that are attached to the circuit board. The components are mounted in an inverted position so that the component contacts are still connected to the top side of the circuit board and the body of the component fits substantially within the precision clearance hole.

Abstract: The invention is a replacement universal printer chip that utilizes a single data table. The replacement printer chip includes a microcontroller that emulates the chip functions of an entire model line of printers made by the same manufacturer. The universal chip identifies and blocks the overwrite locations in a single data table of multiple models of printers made by the same manufacturer. The single data table chip functions correctly on all machine or printer models of a particular manufacturer.
