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: A printing device is provided with a print head having a plurality of nozzles configured to eject ink droplets therefrom, a supplier configured to supply ink contained in a container to the print head, and a controller. The controller is configured to perform obtaining ink information having correlation with a height of a liquid surface of the ink contained in the container, obtaining subject image data representing an image to be printed, generating print data based on the subject image data, and causing the print head to eject ink droplets based on the print data. The generating includes adjusting the print data in accordance with the ink information.

Abstract: In a control system, a controller is configured to determine presence or absence of an obstructed area within the intermediate section, and control movement of the moving body in accordance with a selected one of controlling methods including a first and a second control methods. The first control method causes the moving body to move at a first constant speed in the processing section defined within the intermediate section and at a second constant speed faster than the first constant speed in at least a part of a non-processing section within the intermediate section and other than the processing section, the first control method being selected when the obstructed area is absent. The second control method causes the moving body to move at the first constant speed in the processing section and the non-processing section, the second control method being selected when the obstructed area is present.
