The method includes the following steps: a step of printing a testing chart; a step of reading the testing chart downstream of the printing head; a step of extracting grid boxes; a step of deriving a standard width from width sizes; a step of detecting a box having a width size equal to or larger than a corrected standard width by comparing the width sizes of the respective boxes with the corrected standard width; and a step of determining that a missing nozzle exists upon detection of the box having a width size equal to or larger than the corrected standard width.

Abstract: A liquid ejecting apparatus includes: a support that extends in a second direction intersecting a first direction in which a printing medium is transported; a carriage that is connected to the support and is movable in the second direction; an ejector that is provided in the carriage and ejects a liquid to the printing medium; and a detector that is provided in the carriage and detects a change in posture of the carriage. In a case where the liquid is not ejected from the ejector, the carriage moves in the second direction, and the detector detects the change in posture of the carriage. The detector outputs posture-change amount information based on the change in posture of the carriage. Ejection of the liquid is corrected based on the posture-change amount information.

Abstract: A printing system includes a pair of encoders to compensate for encoder noise in the velocity of a media transport as the transport moves past a plurality of printheads. One encoder monitors a roller that positioned at a location of low thermal stress and the signal generated by this encoder is used by a controller to maintain a constant velocity for the media transport. The second encoder monitors a roller used to drive the media transport and is positioned close to the print zone opposite the printheads. The signal from the second encoder is used to identify a corrected distance between each tic in the tics generated by the second encoder and the corrected distance is used to count a firing distance for generation of a dot clock signal to activate ejectors in a printhead when a substrate has traveled the firing distance.

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.

Abstract: Disclosed is a method of providing adjustment data for a droplet deposition head (such as a printhead), or a data processing component therefor. The method makes use of test data, which has been collected by operating the droplet deposition head (or a test droplet deposition head of substantially the same construction, e.g from the same batch), using a set of test waveforms, at a number of frequencies within a test range, and by recording the volume and velocity of the thus-ejected droplets, with these recorded values (volr, velr) being represented within the test data. Each of the set of test waveforms includes a basic drive waveform and a number of adjusted drive waveforms, each of which corresponds to the basic drive waveform, but with a particular waveform parameter adjusted by a corresponding amount. This waveform parameter is a continuous variable, such as pulse width or pulse amplitude.
