Abstract: The invention relates to a method for printing on a media object supported by a flat bed of a printer, the printer comprising a print head and a camera above the flat bed, the method comprising the steps of detecting a media object on the flat bed surface of the printer by means of a digital camera image captured by the camera, deriving camera coordinates of the media object in the digital camera image, applying a direct transformation from the camera coordinates into print head coordinates of the media object without using coordinates of the flat bed surface, and printing a digital target image on the media object by ejecting recording material on the media object from the print head, the print head controlled according to the print head coordinates appropriate for the media object.

Abstract: An inkjet print head includes an ejection unit having a liquid chamber for holding an amount of liquid, a electromechanical transducer operatively coupled to the liquid chamber for generating a pressure wave in the amount of liquid and a nozzle in fluid communication with the liquid chamber for enabling a droplet of the amount of liquid to be ejected through the nozzle. A method for detecting an operating state of the ejection unit includes the consecutive steps of actuating the electromechanical transducer to generate a pressure wave in the liquid; actuating the electromechanical transducer to suppress a residual pressure wave in the liquid; sensing an amplitude of the residual pressure wave in the liquid; and based on the result of the sensing step determining that the ejection unit is (i) in an operative state if the amplitude of the residual pressure wave is below a threshold or (ii) in a malfunctioning state if the amplitude of the residual pressure wave is above the threshold.

Abstract: A method compensates a failing nozzle of a print head of an inkjet printer. The inkjet printer includes at least one print head, the at least one print head including a plurality of nozzles. A receiving material is moved relatively to the at least one print head. The method includes ejecting droplets of marking material from the plurality of nozzles onto the receiving material forming dots of an image, scanning the printed dots, analyzing the scanned dots for detecting whether a nozzle is failing, determining a group of nozzles, which group of nozzles most likely contains the nozzle that is failing, selecting one nozzle of the group of nozzles, in an image part ejecting compensating droplets of marking material in accordance with a compensation scheme selected as if the one nozzle is failing, scanning the image part, repeating the steps of ejecting and scanning for each other nozzle in the group of nozzles, analyzing each image part, selecting from the image parts a deviating image part, the deviating image part having a highest or lowest print quality of all image parts, selecting a compensation scheme based on the deviating image part, and proceeding with printing, including ejecting compensating droplets in accordance with the selected compensation scheme. An inkjet printer is configured to execute the method.

Abstract: For assessing the functioning of an ejection unit of an inkjet print head, a comparison of a residual pressure wave with a residual pressure wave reference is employed. To enable assessment during printing, multiple residual pressure wave references are provided, each relating to a condition relevant to the residual pressure wave. Such a condition may relate to an actuation status of an adjacent ejection unit which may cause crosstalk, for example. When performing the assessment, the condition during assessment is taken into account, for example for selecting a suitable residual pressure wave reference, such that an appropriate and correct assessment can be performed independent from the conditions during assessment.

Abstract: A printing assembly comprises a medium support surface, a guide assembly and a carriage support structure for moveably supporting a print head carriage on the guide assembly. The guide assembly is arranged to move the print head carriage in a carriage plane, which carriage plane is parallel to the medium support surface. The guide assembly comprises a guide beam; and a guide rail arranged on the guide beam. The guide rail and the guide beam each extend in a scanning direction. The printer carriage support structure comprises a guide frame arranged on the guide rail and the guide frame is moveable in the scanning direction and extends in the scanning direction between a first support position and a second support position. The guide frame is supported on the guide rail at said first support position and at said second support position. A carriage frame is moveably supported on the guide rail through the guide frame. The carriage frame is coupled to the guide frame such that the carriage frame is moveable relative to the guide frame in the carriage plane.

Abstract: An inkjet printing apparatus includes an inkjet print head arranged to be moveable in a direction of movement along a guiding assembly. The guiding assembly includes a support structure; a strip mounted on the support structure, the strip being substantially rigid and straight in a first direction substantially perpendicular to the direction of movement and mounted in such way that a straightness in the direction of movement is provided; and an air bearing system operatively coupled to the strip. The strip extends in a vertical plane, the vertical plane being substantially parallel to the direction of movement and being substantially parallel to the first direction. The air bearing system is configured to control a position of the inkjet print head in a horizontal plane relative to the strip during movement of the print head in the direction of movement, the horizontal plane being substantially perpendicular to the vertical plane. Employing such a strip and a suitable mounting method for mounting the strip on the support structure, it is enabled to select a cost-effective and/or light-weight support structure.
