摘要： The head system includes: a plurality of heads disposed staggered along a first direction; a sub-tank disposed above the heads and configured to distribute a liquid to each of the heads; a plurality of liquid channels; a chiller configured to cool the heads, including a manifold disposed between the heads and the sub-tank in an up-down direction; and a casing having a pair of inner surfaces opposed to each other in a second direction orthogonal to the first direction and the up-down direction. Each of the liquid channels extends linearly parallel to the up-down direction in an entire region between the sub-tank and one of the heads. Each of the plurality of liquid channels and the manifold are aligned in the second direction between the pair of inner surfaces of the casing.

摘要： A waveform selecting process includes selecting one of a plurality of kinds of driving waveforms for each of a plurality of dot elements, based on a density value set to each of the plurality of dot elements in image data. The waveform selecting process includes, for a dot element array of each of the plurality of ejection ports: determining whether a dot element corresponding to a target dot has a second density value and determining whether a subsequent dot element corresponding to a subsequent dot has a first density value and, when both determinations are positive, setting the dot element corresponding to the target dot as a correction-target dot element, the subsequent dot being subsequent to the target dot in the formation order; and selecting one of a first driving waveform and a second driving waveform as a driving waveform of a correction-target dot element.

摘要： A recording apparatus comprising a container to store a sheet of recording medium; a conveyer configured to convey the recording medium in the container; a main tank receiving portion configured to receive a main tank for storing liquid; a sub tank configured to store liquid supplied from the main tank; and a recording head including an ejection surface where ejection openings for ejecting liquid supplied from the sub tank are formed. Each of three projected areas which are an area of the main tank receiving portion, an area of the sub tank, and an area of the recording head, each projected to a virtual plane parallel to a surface of the recording medium contained in the container from a first direction orthogonal to the virtual plane, at least partially overlaps a container projected area which is an area of the container projected to the virtual plane from the first direction.

摘要： A liquid application apparatus comprises: a pair of conveyor rollers including two rollers configured to rotate while pinching a recording medium thereby to convey the recording medium in a first direction; a liquid applicator configured to apply a liquid; and a controller configured to control driving of the pair of conveyor rollers and to control the liquid applicator. The controller executes a calculation process of calculating an estimated value of an amount of extraneous matter attached to the pair of conveyor rollers taking into account weighting data indicating a weighting given, based on an amount of paper dust, to each of areas on the recording medium which areas are arranged in a second direction crossing the first direction.

摘要： A head unit includes a circuit board, a casing, and a head module including: a nozzle plate and a liquid-passage defining member stacked on each other in a stacking direction; a drive element; and an interconnect member. A distance between a first end and a second end of the nozzle plate which are spaced in a first direction is greater than a distance between a third end and a fourth end of the nozzle plate which are spaced in a second direction. A distance between a seventh end and an eighth end of the circuit board which are spaced in the stacking direction is greater than a distance between a fifth end and a sixth end of the circuit board which are spaced in the first direction.

摘要： A recording apparatus includes a controller configured to: decrease the number of recording pages which is stored in a storage in response to completion of recording on a recording medium on a page-by-page basis; increase the number of recording pages in response to an increase in an amount of image data in the storage; determine whether the number of recording pages is greater than or equal to a first number; control a drive source and a recording device to convey the recording medium at a first speed and perform recording when the number of recording pages is less than the first number; and control the drive source and the recording device to convey the recording medium at a second speed greater than the first speed and perform the recording when the number of recording pages is greater than or equal to the first number.
