  • Technique for converting single cartridge monochrome printer to multi-cartridge color inkjet printer
    Patent number: 5959647
    Abstract: A simplified technique and conversion kit allows a user to change a single cartridge monochrome printer into a multiple cartridge color printer without having to use the same slots in the carriage for different print cartridges. As part of the conversion, modifications are made to the carriage by manually removing a carriage cover, manually removing a service station cover for certain user-activated functions such as primer selectors, and adding a new ROM SIMM to the printer.
