摘要:
An inkjet printer includes at least one print cartridge mounted in a scanning carriage having an ink interconnect coupled, via a flexible tube, to an ink output of a stationary pressure regulator. An ink input of the pressure regulator is connected, via a tube, to a stationary ink supply having replaceable ink cartridges. The print cartridge contains one or more printheads and one or more ink interconnects, one interconnect for each color ink which is printable by the print cartridge. To avoid ink pressure spikes due to the momentum of the ink in the flexible ink tube as the carriage scans across the medium, a flexible diaphragm is incorporated in the ink chamber of the print cartridge. The print cartridge is inserted in the scanning carriage so as to create a fluid coupling between the printhead and the flexible tube leading to the scanning carriage.

Described is an inkjet print cartridge including an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber; said ink firing chambers arranged in a first chamber array and a second chamber array and said firing chambers spaced so as to provide 600 dots per inch printing; an ink channel connecting said reservoir with said ink firing chambers, said channel including a primary channel connected at a first end with said reservoir and at a second end to a secondary channel; a separate inlet passage for each firing chamber connecting said secondary channel with said firing chamber for allowing high frequency refill of the firing chamber; a group of said firing chambers in adjacent relationship forming a primitive in which only one firing chamber in said primitive is activated at a time; a first circuit on said substrate connected to said firing elements; and a second circuit on said cartridge connected to said first circuit, for transmitting firing signals to said ink firing elements at a predetermined frequency. The preferred configuration of the nozzle member, ink channels, and firing chambers allows a printing resolution of 600 dots per inch.

This invention provides an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the nozzle member is associated with a vaporization chamber and heater element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edge of the substrate gain access to the ink channels and to the vaporization chambers.

Disclosed is an inkjet print cartridge including an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber along a top surface of said substrate and having a first outer edge along a periphery of substrate; the first outer edge being in close proximity to the ink firing chambers. The ink firing chambers are arranged in a first chamber array and a second chamber array and with the firing chambers spaced so as to provide 600 dots per inch printing. An ink channel connects the reservoir with the ink firing chambers, the channel including a primary channel connected at a first end with the reservoir and at a second end to a secondary channel; the primary channel allowing ink to flow from the ink reservoir, around the first outer edge of the substrate to the secondary channel along the top surface of the substrate so as to be proximate to the ink firing chambers. A separate inlet passage defined by a barrier layer for each firing chamber connecting the secondary channel with the firing chamber for allowing high frequency refill of the firing chamber. The separate inlet passage for each firing chamber having peninsulas and pinch points formed in the barrier layer to prevent cross-talk and overshoot during high frequency operation. A group of the firing chambers in adjacent relationship forming a primitive in which only one firing chamber in said primitive is activated at a time. A first circuit on said substrate connect to the firing elements and a second circuit on the cartridge connect to the first circuit, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz. The preferred configuration of the nozzle member, ink channels, and vaporization chambers allows a printing resolution of 600 dpi and a firing rate of greater than 9 kHz.
