Abstract: A liquid discharging system includes a head and a controller system. The head has a first nozzle row including a first nozzle and a second nozzle row including a second nozzle. The nozzles in the first and second nozzle rows are aligned in a first direction, and the first nozzle row and the second nozzle row are arrayed along a second direction, which intersects with the first direction. The controller system is configured to control the head to discharge liquid of the same type from the first nozzle and the second nozzle at a recording medium when the first nozzle and the second nozzle are each located at a same position with respect to the recording medium while the head moves in the second direction relatively to the recording medium.

Abstract: A non-transitory computer readable medium recorded with a program for controlling an external apparatus which has a memory and which is configured to communicate with a liquid ejecting apparatus is provided. The program allows a computer to acquire nozzle information from the liquid ejecting apparatus so that the nozzle information is stored in the memory. The program allows the computer to execute the nozzle information acquiring process at a first timing if the nozzle information, which is stored in the memory, fulfills a first condition, or the program allows the computer to execute the nozzle information acquiring process at a second timing having a frequency lower than that of the first timing if the nozzle information, which is stored in the memory, fulfills a second condition.

Abstract: A liquid ejecting apparatus includes an ejection head including a plurality of nozzles communicating with a pressure chamber and an actuator configured to apply pressure on liquid stored in the pressure chamber, a carriage, a storage storing information relating to a first timing when a non-ejecting flashing operation is started, and a controller. The actuator applies pressure on the liquid in the pressure chamber in the non-ejecting flashing operation so as to vibrate, without ejecting, the liquid in the plurality of nozzles of the ejection head, while the carriage is decreased in speed so as to be stopped. The controller is configured to select, based on status information, one of the first timing and a second timing, and start the non-ejecting-flashing operation at the selected timing while the carriage is decreased in speed so as to be stopped.

Abstract: A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.

Abstract: There is provide an image processing apparatus including a carriage with a recording head and a sensor mounted thereon, a conveyer, and a controller. The controller carries out: acquiring a recording data, a front edge margin, and a tail edge margin, determining whether or not at least one of first and second reference values is less than a threshold value, and a positioning process. When at least one of the first and second reference values is less than the threshold value, then the controller carries out: a front edge detecting process, a first recording preparation process, and a recording process. When at least one of the first and second reference values is not less than the threshold value, then the controller carries out: a second recording preparation process, and the recording process.

Abstract: A printing apparatus includes: a print execution section and a controller. The print execution section includes: a printing head having nozzles, an ink having a specified color being discharged from the nozzles; a head driver which drives the printing head to form dots having the specified color on a printing medium by discharging the ink having the specified color from the nozzles; and a movement mechanism which moves the printing medium relative to the printing head. The controller is configured to: obtain object image data; generate, by using the object image data, a plurality of pieces of dot data indicating formation states of the dots having the specified color, for a plurality of pixels; and print a printing image by causing the print execution section to execute discharge of the ink having the specified color and movement of the printing medium by use of the pieces of dot data.

Abstract: A controller of a liquid ejection device is configured to receive a preparation signal instructing preparation to eject the liquid, the preparation signal being externally issued upon issuance of an ejection instruction to eject the liquid toward a target medium. The controller is configured to start receiving ejection data after the preparation signal is received, the ejection data being externally transmitted on condition that the ejection instruction is issued and after the preparation signal is issued. The controller is configured to control the liquid ejection head to eject the liquid toward the target medium through the multiple nozzles based on the ejection data. After receiving the preparation signal and before receipt of the ejection data is completed, the controller is configured to control the liquid ejection head to eject liquid through the multiple nozzles and examine at least a part of the nozzles for ejection-defectiveness based on the determination signal.

Abstract: When a specified image is recorded while ranging over a boundary between a first dot recording range and a second dot recording range, a controller of an image recording apparatus judges whether or not a predetermined condition is fulfilled, the predetermined condition including at least one of a first condition which relates to a duty and a second condition which relates to a positional deviation in a scanning direction of a landing position of a liquid. If the predetermined condition is fulfilled, the dot belonging to a correcting portion is formed by correcting discharge in which the liquid in a discharge amount smaller than a set discharge amount is discharged. If the predetermined condition is not fulfilled, the dot belonging to the correcting portion is formed by ordinary discharge in which the liquid in the set discharge amount is discharged.
