Abstract:
A pen assembly for an ink-jet printer, comprising:a carriage member defining a socket therein and having a first set of conductive leads attached thereto, the first set of leads having ends that are exposed to protrude into the socket;a print head assembly removably mounted to the carriage and carrying an ink-jet print head and a second set of conductive leads connected to the print head, the second set of leads being shaped to define exposed ends, part of the print head assembly fitting into the socket so that the ends of the first set of leads contact the ends of the second set of leads thereby providing conductive paths between the first set of leads and the second set of leads, the ends of the second set of leads protruding outwardly from the print head toward an end wall of the socket assembly so that the ends of the first set of leads obstruct movement of the ends of the second set of leads when the print head assembly is removed from the carriage member, thereby to resist removal of the print head assembly from the carriage member; andan ink supply coupled to the carriage member for supplying ink to the print head.
