    摘要： An image forming apparatus, an image formation method, and a non-transitory recording medium. The image forming apparatus acquires print data, converts the print data into ejection data to be used by the recording head to eject ink, applies to the ejection data, a correction mask pattern to change a manner of ink ejection for each nozzle of a nozzle row, the nozzle row including a plurality of nozzles arranged in a sub scanning direction of the recording head, and causes each nozzle of the recording head to eject ink onto the recording medium based on the ejection data to which the correction mask pattern is applied.

    摘要： An ejection apparatus includes an ejection head having an ejection port, a droplet detection unit, an acquisition unit, a control unit, and a decision unit. The droplet detection unit detects that a droplet ejected from the ejection port has reached a predetermined position. The acquisition unit acquires information regarding a velocity of movement of the detected droplet. The control unit controls the ejection head to eject the droplet from the ejection port. The decision unit decides a number of consecutive ejections of a plurality of droplets from the ejection head based on the acquired information regarding the velocities of each of the plurality of droplets ejected consecutively and detected by the droplet detection unit. If the acquisition unit acquires the information regarding velocities of detected droplets, the control unit controls the ejection head to consecutively eject the droplets from the ejection head based on the decided number of consecutive ejections.

    摘要： A printing device comprises a droplet generator for generating a droplet of printing fluid, a droplet detector for detecting a generated droplet of printing fluid, and a controller. The droplet detector is moveable along an axis. The controller is to cause the droplet detector to be positioned at a known location along the axis, cause the droplet generator to generate a droplet, receive a measurement signal from the droplet detector, and determine a location of the droplet generator based on the received measurement signal and the known location.

    摘要： A droplet detection device includes a light emitting element that emits a detection light for detecting shielding of at least one part by a microdroplet discharged from a nozzle of a head of an ink jet printer in a direction intersecting an advancing direction of the microdroplet; a light receiving element; and a pair of wall portions facing each other and enabling the microdoplet to pass therebetween; where the wall portions have one part of a light path of the detection light from the light emitting element to the light receiving element and allows at least one part of the detection light to be reflected and to reach the light receiving element, and the detection light has a width in a direction equal to a spacing in the direction of the wall portions in a region sandwiched by ends on the light emitting element side of the wall portions.

    摘要： A continuous ink jet print head (10), including: an ink droplet generator (116) configured to emit an ink droplet (158) along an undeflected droplet flight path (30); a charge electrode (118) configured to impart a charge to the ink droplet; deflector plates (120A, 120B) adjacent the undeflected droplet flight path, downstream from the charge electrode, and configured to deflect the ink droplet to a deflected droplet flight path that lies within a range of deflected flight paths bounded by at least deflected droplet flight path and a most deflected droplet flight path; a gutter (122) configured to receive an ink droplet traveling along the undeflected droplet flight path; and an ink buildup sensor (102) configured to detect an accumulation of ink (140) relative to a droplet flight path disposed within the range of deflected flight paths.
