摘要： A liquid ejection device comprising:
- a liquid duct system (14) having a plurality of nozzles (10), a plurality of pressure chambers (12) communicating with the nozzles (10), and a liquid supply line (24) communicating with the pressure chambers (12),
- a plurality of actuators (22) arranged to pressurize the liquid in the pressure chambers (12) for ejecting droplets of liquid through the nozzles (10), and
- a dampening device (26) comprising a cavity (28) that is in fluid communication with the duct system (14) and is delimited by a resilient foil (30) for dampening pressure waves in the liquid,
- characterized in that the resilient foil (30) is pre-formed in a corrugated shape.-

摘要： The present invention relates to a method and apparatus for media calibration in an inkjet printer, wherein the inkjet printer comprises a printing surface on top of which a recording medium is displaced, a strip of a first color on top of the printing surface, and a light source. The method comprises illuminating the recording medium with the light source, wherein the color of the wavelength of the light source with a higher energy substantially coincides with the first color. Further it comprises selecting a second color for printing at least one calibration marker such that a contrast between the first and the second color causes at least an amount of direct and reflected light from the light source to be absorbed by the at least one calibration marker, and printing at least one calibration marker of the second color on the recording medium.

摘要： A method for detecting an operating state of an ejection unit during the printing of an object of a print job the method comprising determining whether the ejection unit is in an operative state or in a malfunctioning state by analyzing a residual pressure wave generated in the liquid in a duct of the ejection unit by an actuation pulse. Further, the method comprises scanning the location of a recording medium onto which liquid has been ejected in order to perform an additional determination of whether the ejection unit is in an operative state or in a malfunctioning state. The method uses both determinations to build feedback information in the form of labeled data that is used in subsequent executions to improve the result of the determinations performed by analyzing a residual pressure wave generated in the liquid. Other aspects of the present invention relate to a droplet ejection device comprising a plurality of ejection units, as well as a printing system comprising the droplet ejection device, and a software product comprising program code on a machine-readable non transitory medium for executing the method in the printing system.

摘要： The invention provides a method for operating a printing system including a printer and a finisher. The invention further provides a printer controller, a printer, a printing system, a computer program product and a software medium. Time ordinarily spent idle by a printer because of a necessary setup time by the finisher is utilized to make more efficient use of time. The otherwise idle time may be used to start printing a sheet of the next print job sooner, or may be used to print a quality assurance sheet that is desired in any case. Measures can also be taken to prevent maintenance actions that can take a lot of time by rendering the idle time of the printer shorter than a trigger time that triggers the maintenance action.

摘要： A device for arranging a print head in a certain position includes a main unit comprising a main frame providing a primary abutting part and a support part; a sub-unit comprising a sub-frame providing a secondary abutting part, a connecting member movable relative to the sub-frame between a first position and a second position, and an urging member for urging the connecting member from the second position towards the first position, and a print head connectable to the connecting member to form a sub-assembly with the sub-unit, wherein the main unit is configured to accommodate a sub-assembly formed by the sub-unit and the print head in a preliminary position in which, with the connecting member in the first position, the print head contacts the support part, and the secondary abutting part is spaced apart from the primary abutting part. The support part is configured to mate with the print head to prevent lateral displacement of the print head relative to the main frame, and the sub-frame is movable relative to the main frame from the preliminary position towards a final position against a force exerted onto the sub-frame by the urging member while the connecting member moves from the first position towards the second position against a force exerted onto the connecting member by the urging member, under the influence of a force exerted onto the print head by the support part, wherein in the final position, the secondary abutting part abuts the primary abutting part.
