Abstract
An inkjet printer is provided. The printer comprises an inkjet printhead having a plurality of nozzles; at least one ink reservoir; and an ink supply system for supplying ink from the reservoir to the plurality of nozzles, the ink supply system comprising at least one pressure-dampening structure for dampening pressure fluctuations experienced by the nozzles. A distance between the pressure-dampening structures and at least one of the nozzles is less than 100 microns.
Claims19
An inkjet printer comprising:
- an inkjet printhead comprising a plurality of nozzle chambers covered by a nozzle plate, said nozzle plate having a plurality of nozzle apertures defined therein, said nozzle plate comprising a plurality of pressure-dampening structures for dampening pressure fluctuations experienced at said nozzle apertures;
- at least one ink reservoir;
- and
- an ink supply system for supplying ink from said at least one ink reservoir to said plurality of nozzle apertures, said printhead ink supply system comprising at least one conduit wall defined by part of said nozzle plate, each pressure-dampening structure being positioned in said part of said nozzle plate,
- wherein a distance between at least one of said pressure-dampening structures and at least one of said nozzle apertures is less than 100 microns, and
- wherein said nozzle plate comprises at least 100 pressure-dampening structures.
An inkjet printhead comprising a plurality of nozzle chambers covered by a nozzle plate, said nozzle plate having a plurality of nozzle apertures defined therein, said nozzle plate comprising a plurality of pressure-dampening structures for dampening pressure fluctuations experienced at said nozzle apertures, wherein at least one conduit wall of a printhead ink supply system is defined by part of said nozzle plate, each pressure-dampening structure being positioned in said part of said nozzle plate, wherein said nozzle plate comprises at least 100 pressure-dampening structures.
