摘要： An inkjet print cartridge is described which has a first fill port, for initially filling the print cartridge with ink, and a refill port for recharging the print cartridge. The refill port includes a slideable valve which is engageable with a valve on an external ink reservoir to create an airtight fluid communication path between the print cartridge reservoir and the external ink reservoir.

摘要： A closed ink replenishment system for replenishing the supply of ink in negative pressure spring-bag reservoirs in a printer/plotter. A tube runs between each cartridge reservoir and an auxiliary reservoir mounted to the printer/plotter frame to form the closed ink system. As ink is depleted from the spring-bag reservoir during printing operation, the negative pressure in the cartridge increases, drawing ink through the tube from the auxiliary reservoir into the cartridge until the negative pressure decreases to an equilibrium point. As a result, the volume of ink within the spring-bag reservoir remains substantially constant so long as there is ink remaining within the auxiliary reservoir. This maintains the print quality. The auxiliary reservoir is a flat bag mounted on a spring-biased platform, which acts as a height regulating system. As ink is depleted from the auxiliary bag, the height of the platform and bag increases to maintain a constant pressure and elevation head at the spring-bag reservoir.

摘要： This present invention is embodied in a printing system with thermally efficient heat transfer capabilities for reducing dimpling of a nozzle member during fabrication of the printhead portion of an inkjet printer. The printing system of the present invention includes a printhead assembly and an ink supply for printing ink on print media. The printhead assembly includes a printhead body having a heat transfer device, ink channels and a nozzle member having plural nozzles coupled to respective ink channels. The nozzle member is secured to the printhead body with a suitable adhesive layer. The heat transfer device can be defined by a portion of or the entire printhead body for reducing thermal expansion of the printhead body during exposure to heat. Namely, the heat transfer device of the printing system of the present invention is capable of efficiently reducing thermal expansion of the printhead body during the process of adhering (which includes heating and curing the adhesive) the nozzle member to the printhead body. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.
