摘要:
The systems and methods of this invention allows for an electrical contact structure of the drop ejecting transducer in an inkjet printhead to be designed in such a way that the relatively thick electrical contact lines are not in the ink drop ejection path between the drop ejector transducer and the corresponding nozzle. Such a design thereby minimizes any visible defects due to misdirected satellite drops.

A method of printing with a fluid jet printer (10) is provided. The printer (10) has a printhead (12) with a fluid ejecting face (12a) facing a recording medium (14), the fluid ejecting face (12a) having at least one fluid ejector (18) arranged thereon. The method includes: imparting movement to at least one of the fluid ejector (18) and the recording medium (14) such that the recording medium (14) moves relative to the fluid ejector (18) along a fast scan direction (32) at a velocity (vm); and, selectively ejecting fluid from the fluid ejector (18) toward the recording medium (14) as the movement is being imparted, such that: (i) a main drop is formed and has a first velocity (vd) in a first direction; and, (ii) a satellite droplet is formed and has a second velocity (vs) in a second direction that forms an angle (θ) with respect to the first direction, wherein θ substantially satisfies the equation: tan θ=vm[1/(vs cos θ)−1/vd].

摘要:
A printer with reduced required space for printbar substrates in a printhead is disclosed. A first printbar has of a plurality of first die modules, for applying a first color, spaced apart so as to have gaps between each die module and located on a top surface of a first substrate. A second printbar has of a plurality of second die modules, for applying a second color, different for the first color, spaced apart so as to have gaps between each die module and located on a bottom surface of the first substrate. A third printbar for applying the first color and a fourth printbar for applying the second color, both have die modules, spaced apart on a top surface and a bottom surface of a second substrate, that correspond with the gaps on the top surface and the bottom surface of the first substrate, respectively.
