A marking system includes a valve body including an orifice plate including multiple orifices and multiple micro-valves. Each micro-valve includes an actuating beam movable from a closed position in which a corresponding one of the orifices is sealed by a portion of the actuating beam such that the micro-valve is closed, into a peak position in response to application of a control signal. A controller is configured to generate a control signal for each of the actuating beams, each control signal including a drive pulse having a predetermined voltage such that the actuating beam moves from the closed position into the peak position in which the corresponding orifice is open and returns to the closed position in a characteristic period, wherein the drive pulse has a duration that substantially corresponds to the characteristic period such that the actuating beam is in the closed position after the drive pulse is complete.

Systems and methods for controlling operation of micro-valves for use in jetting assemblies

Methods and systems for forming compound slots in a substrate are described. In one exemplary implementation, a structure contains a plurality of slots in a substrate. The structure also has a trench in the substrate contiguous with the plurality of slots to form a compound slot.

Slotted substrates and methods and systems for forming same

An embodiment includes determining a temperature change of a fluid-ejecting substrate, and determining a mass of fluid ejected from the fluid-ejecting substrate from the temperature change of the fluid-ejecting substrate.

Fluid-dispensing devices and methods

Methods and systems for forming compound slots in a substrate are described. In one exemplary implementation, a method forms a plurality of slots in a substrate. The method also etches a trench in the substrate contiguous with the plurality of slots to form a compound slot.
