摘要： Methods and systems are described herein for driving droplet ejection devices with multi-level waveforms. In one embodiment, a method for driving droplet ejection devices includes applying a multi-level waveform to the droplet ejection devices. The multi-level waveform includes a first section having at least one compensating edge and a second section having at least one drive pulse. The compensating edge has a compensating effect on systematic variation in droplet velocity or droplet mass across the droplet ejection devices. In another embodiment, the compensating edge has a compensating effect on cross-talk between the droplet ejection devices.

摘要： A fluid droplet ejection device including a body defining a plurality of fluid paths that each include an inlet including a flow restriction, a pumping chamber, and a nozzle opening communicating with the pumping chamber for discharging fluid droplets. An actuator is associated with each pumping chamber. The pumping chamber has a largest dimension that is sufficiently short and the flow restriction provides sufficient flow resistance so as to provide a fluid droplet velocity and/or volume versus frequency response that varies by less than plus or minus 25% over a droplet frequency range of 0 to 40 kHz. Also disclosed are fluid droplet ejection devices in which the ratio of the inlet flow resistance to the pumping chamber flow impedance is between 0.15 and 0.9, the pumping chamber has a time constant for decay of a pressure wave in the pumping chamber that is less than 25 microseconds.

摘要： A method for operating a printhead of a continuous inkjet printer comprising: producing at least one ink jet in a cavity of the print head; electrostatically separating drops or sections of one or more of the jet intended for printing from drops or sections that do not serve for printing; exiting from the cavity drops or sections of ink intended for printing, through a slot open on the outside of the cavity; and circulating at least one flow of air along the outlet slot of the cavity in a direction essentially perpendicular to at least one jet of ink emitted by the printhead and intended for printing. The air having a water vapor pressure lower than the water vapor pressure defined by 100% relative humidity at the coldest temperature of the printer.
