  • Patent number: 10710376
    Abstract: The inkjet position adjustment method includes the following steps. A three-dimensional digital model is obtained, and a slicing processing is performed on the three-dimensional digital model to generate a layer object having a cross-sectional contour. A normal direction of an object surface corresponding to the layer object is obtained from the three-dimensional digital model. When the normal direction points to a negative direction of a first axis, a surface tilt degree of the object surface corresponding to the layer object is obtained, and an inner-shift amount of an inkjet position of the layer object is calculated according to the surface tilt degree. An inkjet region of the layer object is obtained according to the inner-shift amount and the cross-sectional contour. After controlling a print module to print the layer object, an inkjet module is controlled to inject ink on the layer object according to the inkjet region.

  • Patent number: 10647110
    Abstract: A method detects defective printing nozzles in an inkjet printing machine having a computer. The method includes printing a multi-row nozzle test chart for detection purposes, the test chart contains a number of horizontal rows of equidistant vertical lines printed periodically and disposed underneath one another. Wherein in every row of the nozzle test chart periodically only those respective printing nozzles of the print head contribute to the first element of the nozzle test chart that correspond to the specified number of the horizontal rows. An area coverage element geometrically associated with the nozzle test chart is printed. Both elements are recorded by an image sensor and both elements are evaluated by the computer. Defective printing nozzles are identified by evaluating the recorded nozzle test chart by the computer. Defects are allocated in the area coverage element to the printing nozzles in the nozzle test chart by the computer.

  • Patent number: 10639885
    Abstract: A liquid discharging apparatus includes a nozzle, a drive signal generation unit that generates a drive signal for driving a piezoelectric element, and a discharge abnormality detection unit that detects a change of an electromotive force of the piezoelectric element, which is caused by residual vibration in a cavity after the drive signal is supplied. The drive signal generation unit generates a first drive signal for checking whether or not a first discharge abnormality caused by a foreign substance adhering to a surface on which the nozzle opens occurs and a second drive signal for checking whether or not a second discharge abnormality caused by a cause other than the foreign substance occurs. A potential of the first drive signal when the discharge abnormality detection unit performs checking is different from a potential of the second drive signal when the discharge abnormality detection unit performs checking.
