摘要： A method of removing an electric crosstalk contribution is disclosed. This crosstalk exists in a monitoring signal from a monitored electro-mechanical transducer in a device comprising a plurality of electro-mechanical transducers which are driven by actuation signals so as to produce acoustic waves in an acoustic frequency range. The method comprises the steps of : (a) applying an actuation signal to at least one of the transducers other than the monitored transducer; (b) detecting the monitoring signal in a high frequency range outside of the acoustic frequency range; (c) deriving, from the detected monitoring signal, a number of parameters that characterize the electric crosstalk; and (d) using said parameters to calculate the electric crosstalk contribution in the acoustic frequency range.

摘要： In some examples, a system includes a printhead including a printer fluid nozzle, an air valve in fluid communication with a channel of the nozzle to: (1) create back pressure in the channel when the air valve is closed and printer fluid is ejected through the nozzle and (2) release back pressure in the channel when the air valve is open, an ejector to eject printer fluid through the nozzle to form a meniscus of printer fluid in the channel when the air valve is closed, a pressure sensor to measure pressure within the channel, and an indicator in electrical communication with the pressure sensor. The indicator can, for example, indicate whether there is an air leak in the channel by determining whether the pressure in the channel is within a predetermined pressure range after a predetermined idle time following the formation of the meniscus in the nozzle.

摘要： There is a provided a liquid droplet discharging control device which causes a liquid droplet discharging apparatus including a head, in which a plurality of nozzles are arranged in a predetermined direction, to perform printing and which is capable of executing a nearby compensation process in which, on the basis of a dot position on which a predetermined nozzle for black ink forms a dot, a nearby nozzle that forms a dot in the vicinity of the dot forms a dot and executing a composite compensation process in which dots of a plurality of different colors are overlap-printed on a predetermined dot position. The liquid droplet discharging control device includes a parameter acquiring unit that acquires parameters corresponding to the degree of liquid spreading toward a periphery after adhesion of a liquid droplet to a medium, and a compensation switching unit that switches between execution of the nearby compensation process and execution of the composite compensation process on the basis of the parameters.

摘要： A printing apparatus is provided with a transport mechanism section that transports work, a printing mechanism section that has multiple nozzle groups, which perform printing by discharging an ink onto the work as liquid droplets, and control section that controls the actions of the transport mechanism section and the printing mechanism section. In addition, the printing mechanism section includes a first nozzle row that forms a first printing region, a second nozzle row that forms a second printing region, and an overlapping section in which the first nozzle row and the second nozzle row overlap. Further, the control section prohibits overlapping of the first printing region with the second printing region on the work when forming the third printing region.
