Abstract: Suitable preliminary discharge conditions are set for a recording head using reaction liquid in bidirectional recording. While the recording head makes a reciprocating motion and scans a recording medium, a preliminary discharge of the reaction liquid is executed after recording on the recording medium from discharge ports on the rear side in a direction in which the recording head travels and a preliminary discharge of ink is executed when a preliminary discharge of the reaction liquid is not executed.

Abstract: In a print apparatus for performing a print by a scan of a print head with heaters generating thermal energy for ejecting ink, a temperature of the print head is detected before the scan of the print head, and when the detected temperature exceeds a threshold temperature, the print head is controlled to wait. Information relating to the cumulative number of drives of the heater in the print head is acquired and, based upon this information, the threshold temperature is changed to a lower temperature as the cumulative number of the drives increases. An excessive temperature rise of the head is restricted and also a throughput reduction is reduced as much as possible.

Abstract: A printing apparatus includes a print unit, an acquisition unit, and a setting unit. The print unit performs printing on a sheet by repeating reciprocating scans of a print head. The acquisition unit acquires information on a temperature of the print head. The setting unit sets a wait time to start a next scan after one scan. The setting unit increases the wait time by a predetermined additional time for each subsequent scan once a value acquired by the acquisition unit exceeds a first threshold, unless the value falls below a second threshold.

Abstract: A catcher is supported on a base to be capable of reciprocal movement between a standby position where a striker can be caught or released and a final position, and moves slidingly toward the final position after rotating at a fixed angle from the standby position during forward movement from the standby position. Holding of the state in which the catcher is in the standby position, and the aforementioned sliding movement, are accomplished by urging of an urging device provided on the base. The aforementioned holding is released and forward rotation of the catcher is started when the striker is caught by the catcher in the standby position by forward movement of a movable body, and this forward movement is assisted by the aforementioned urging from mid-course of this forward movement.

Abstract: The invention prevents inconveniences from being caused by ejection failure and unintended mixing of different colors. To this end, the invention performs preliminary ejection of ink after a wiping action to sweep mist adhering to a face of a printing head, in which an ejection opening is formed. Moreover, the amount of ink to be wastefully consumed by the preliminary ejection after the wiping is reduced. To this end, the number of preliminary ejections is regulated. The degree of adherence of mist to the ejection-opening-formed face depends on the amount of printing (the number of printed sheets, the number of ink ejections for printing, or the like). So, at the time of the preliminary ejection after the wiping, the number of ink ejections in the preliminary ejection is regulated in accordance with the amount of printing that has been done since the last wiping action.

Abstract: It is to improve the robustness and the data transfer reliability of a network. When the destination node is the sixty sixth wireless device D66, the second wireless device D2 determines that there is no destination node among neighboring nodes based on the parent-and-child-node information of the first neighboring node information to transfer the data to the first wireless device D1 as a parent node. The first wireless device D1 can communicate within a communicable range AR1 and memorizes network information of the zeroth wireless device D0, the second wireless device D2, the seventh wireless device D7, the eighth wireless device D8, and the seventeenth wireless device D17. The first wireless device D1 determines that the sixty sixth wireless device D66 as a destination node exists at the neighborhood of the seventh wireless device D7 to transfer the data to the seventh wireless device D7.

Abstract: The present invention has an object to provide an inkjet printing apparatus that can realize both high quality image formation and improvement of a device life caused by the reduction of a mist amount of a processing liquid. The present invention is provided with a control unit that can independently control an ink ejection condition in an ink ejection unit and a processing-liquid ejection condition in a processing-liquid ejection unit. The control unit controls the ejection condition in each ejection unit so that the mist amount of the processing liquid ejected from the processing-liquid eject unit is smaller than that of the ink ejected from the ink eject unit.
