  • Patent number: 6948798
    Abstract: An apparatus for horizontally loading and unloading an ink-jet print cartridge from a carriage in a printer. The apparatus includes a generally rectangular print cartridge, an elongate supporting lip located on a side wall of the print cartridge, a carriage body, a chute mounted on the carriage for receiving the print cartridge, and a generally horizontal rail on a side wall of the chute for guiding the print cartridge into the carriage. In operation, the apparatus horizontally loads a print cartridge into a carriage by translating the print cartridge horizontally forward into a carriage, engaging a lip on the print cartridge with a guide rail on the carriage, sliding the print cartridge up and over a datum on the carriage with the guide rail and latching the print cartridge in the carriage.
