Abstract
An ink jet printer having an inking system that includes an ink jet cartridge, a large ink reservoir mounted on the ink jet printer at a location which is remote from the ink jet cartridge and tubing connecting the ink reservoir to the ink jet cartridge. The tubing and the ink reservoir are permanently mounted within the ink jet printer. Only the ink jet cartridge needs to be replaced, because the jet plate has a finite life span during which the print quality from the jet plate is satisfactory. The ink jet cartridge includes a quick release fitting which enables the easy disconnection of an old ink jet cartridge and reconnection of a new ink jet cartridge with the tubing. Further, the size of the ink jet cartridge is reduced since almost all of the ink storage is moved to a location which is remote from the ink jet cartridge. By removing a majority of the ink from the carriage assembly, the amount of weight attached to the carriage assembly is reduced and thus the amount of power required to move the carriage is reduced.
