    Abstract: An ink jet printing apparatus includes a print head having a nozzle array (N1 - N320) and which scans across the print medium in a scan direction. The nozzle array includes first and second substantially columnar nozzle arrays (34,36), each aligned with a print medium advance direction. Each substantially columnar array has an upper subarray pair including an upper left and an upper right subarray of nozzles (C84, C83; C74, C73), each including a substantially linear arrangement of n nozzles having equal nozzle-to-nozzle spacings. Each upper right subarray is offset from the corresponding upper left subarray in the scan direction by a first spacing and in the print medium advance direction by one-half of the nozzle-to-nozzle spacing. The second substantially columnar array of offset from the first substantially columnar array in the second direction by a second spacing and in the print medium advance direction by one-forth of the nozzle-to-nozzle spacing.

    Abstract: An ink jet print head has first nozzles (10) of a first diameter for ejecting droplets of ink having a first mass, and second nozzles (12) of a second diameter for ejecting droplets of ink having a second mass. The first diameter is larger than the second diameter, and the first mass is larger than the second mass. First and second heater-switch pairs are connected in parallel on a substrate of the print head. The first heater-switch pairs include first heaters adjacent corresponding first nozzles, and the second heater-switch pairs include second heaters adjacent corresponding second nozzles. The first (14) and second (16) heaters are composed of electrically resistive material occupying first and second heater areas on the substrate (4).

    Abstract: An inkjet printhead heater chip has a silicon substrate with a heater stack formed of a plurality of thin film layers thereon for ejecting an ink drop during use. The thin film layers include: a thermal barrier layer on the silicon substrate; a resistor layer on the thermal barrier layer; a doped diamond-like carbon layer on the resistor layer; and a cavitation layer on the doped diamond-like carbon layer. The doped diamond-like carbon layer preferably includes silicon but may also include nitrogen, titanium, tantalum, combinations thereof or other. When it includes silicon, a preferred silicon concentration ranges from 20 to 25 atomic percent. A preferred cavitation layer includes an undoped diamond-like carbon, tantalum or titanium layer. The doped diamond-like carbon layer ranges in thickness from 500 to 3000 angstroms. The cavitation layer ranges from 500 to 6000 angstroms. Inkjet printheads and printers are also disclosed.
