ABSTRACT:
An ink-jet type printer having a self-contained, unitary print-head and ink-supply cartridge which can be readily inserted or removed from the printer without requiring disconnection of or user-exposure to any part of the ink reservoir or ink delivery system. The large-capacity ink reservoir in the cartridge is separate from the ink delivery system and connected thereto by flexible hoses which allow the print-head to be moved independently from the ink supply. A drive gear for the print-head motion system, enclosed in the print-head and ink supply cartridge is partially exposed such that it engages a motor disposed within the printer housing when the cartridge is inserted into the printer housing. An elongated shutter mechanism in the cartridge opens during printing to expose the print-head to the printing surface. When the ink reservoir is exhausted, the cartridge is removed from the printer housing in a single motion.
