摘要： A fluid ejector head includes a die with a plurality of fluid ejector units, each fluid ejector unit comprising a pumping actuator having a drive electrode, and a manifold that contacts the first side of the die to define a module volume in fluidic communication with a drainage volume. The module volume is defined in part between the manifold and at least a portion of plurality of fluid ejector units, and the drainage volume is located apart from the fluid ejector units. The module volume, in comparison to the drainage volume, has a greater ratio of interior surface area to volume or has a greater percentage of interior surface area covered by a non-wetting coating.

摘要： A method for causing fluid to be ejected from a fluid chamber of a jet in a printhead. An actuator is actuated with a first energy imparting pulse to push fluid away from the actuator and toward a nozzle. Following a lapse of a first interval, the actuator is actuated with second energy imparting pulse to push fluid away from the actuator and toward the nozzle. Following a lapse of a second interval as measured from the second energy imparting pulse, the actuator is actuated with a break-off pulse to cause fluid extending out of an orifice of the nozzle to break off from fluid within the nozzle, wherein the second lapse is longer than the first lapse and is an inverse of the meniscus-jet mass frequency.
摘要翻译：一种用于使流体从喷头的流体室喷射到打印头中的方法。致动器通过第一能量施加脉冲致动，以将流体推离致动器并朝向喷嘴。在经过第一间隔之后，致动器由第二能量施加脉冲致动，以将流体推离致动器并朝向喷嘴。在从第二能量施加脉冲测得的经过第二间隔之后，致动器以断开脉冲致动，以使流出喷嘴孔口的流体从喷嘴内的流体中分离出来，其中第二次流逝比第一次流逝长，并且是弯液面喷射质量频率的倒数。

摘要： In the ink jet printing system described in the specification, a hot melt ink jet printhead having two ink reservoirs is coupled through an ink supply line to a remote hot melt ink supply and a temperature controller is arranged to control the temperatures of the ink in the remote ink supply, the supply line, the ink reservoirs in the printhead and passages leading from the reservoirs to the ink jet orifices at selected temperature levels to inhibit high-temperature degradation of the ink while permitting the ink to be jetted at the desired jetting temperature. In addition, a pressure control system controls the pressure of the ink in the printhead at one or more selected levels to permit the printhead to be used at different orientations and to permit purging of air bubbles and contaminants from the orifice passageways and to supply a relatively high vacuum to a deaerator in the printhead to extract dissolved air from the ink. A check valve in the ink supply line permits the printhead to be positioned at different elevations with respect to the remote ink supply without causing any undesired flow of ink between the reservoir and the printhead.

摘要： In the embodiment of the cleaning device described in the specification, a web of paper is movable past the orifice plate of an ink jet head from a supply roll to a take-up roll. The cleaning device has a movable front end portion with two pressure bars positioned to urge the web of paper against two portions of the orifice plate, one portion being in line with the orifices and the other below the orifices. The pressure bar supports are arranged so that the bar positioned in line with the orifices engages the web after the other bar has urged the web against the orifice plate. The cleaning device also collects ink ejected during purging of air from the system and may be positioned to prevent ejection of ink during an internal purging operation.
