  • Patent number: 11192357
    Abstract: Although a conventional method of inspecting an ink discharge state in which the temperature change of the heater is detected enables accurate and high-speed inspection, due to the situation in which the inspection was performed, appropriate post-processing depending on the situation cannot be executed based on a result of the inspection. Therefore, it is necessary to determine the ink discharge state in detail. A plurality of modes are provided in accordance with the purpose of performing an inspection of the ink discharge state, and a discharge inspection threshold is provided for each of these modes. By selectively executing or continuously executing these modes, it is possible to determine the ink discharge state in more detail.

The controller, based on the determined ink amount being less than a first threshold value, causes the recording head to discharge ink of the determined ink amount in ? times of the flushing processes, and based on the determined ink amount being the first threshold value or more, causes the recording head to discharge ink of the determined ink amount dispersed in ?(?>?) times of the flushing processes.

  • Patent number: 10201976
    Abstract: An inkjet printer has a printing head, a sheet conveying mechanism, a carriage mounting a printing head and configured to be reciprocally movable in a printing area and non-printing area. A cap is provided to be movable between a capping position an uncap position. A controller of the inkjet printer is configured to execute a printing process, a standby process, and a capping process in which the controller causes the carriage to move to the non-printing area and moves the cap from the uncap position to the capping position. The controller causes the carriage to move into the printing area when the next printing command is received after the standby process is finished and before the carriage moving process has been completed.

  • Patent number: 10195857
    Abstract: A jet recovery print process is performed each time before printing a print job, when an inactivity period of non-printing has been exceeded, or during a long print job, where the jets might clog with debris. The jet recovery print process ejects the ink from the inkjets by printing (using the inkjets) a sacrificial page in a jet recovery pattern, while operating the actuators in the inkjets at their maximum voltage rating. The jet recovery pattern is designed to purge all the ink from all the inkjets. Thus, in the jet recovery print process, the controller operates the actuators at their maximum voltage rating so as to provide a higher driving force for the ink to be ejected from the inkjets and thereby make the purge process more effective.

  • Patent number: 10076908
    Abstract: Ink supplies and methods to prepare an ink supply are disclosed. An example ink supply for a printer includes an ink chamber within a housing of the ink supply. The housing is removably installable within the printer. The ink chamber is to store ink. The ink supply further includes a machine readable storage medium to store a first priming parameter. The machine readable storage medium is carried by the housing of the ink supply. The first priming parameter has a value to cause the printer to configure a first priming procedure of the printer. The first priming parameter has precedence in configuring the first priming procedure over a first corresponding priming parameter stored in a second machine readable storage medium of a second ink supply installed in the printer.

    Abstract: A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.

  • Patent number: 9889668
    Abstract: A printing system, print control device, and print control method enable non-technical users without specific technical knowledge to appropriately set the flushing conditions of a printer. A host that sends commands to an inkjet printer that prints on a print medium provides a user interface for selecting an operating mode prioritizing the throughput of the printing operation, or a normal operating mode. When the operating mode prioritizing printer throughput is selected using the user interface, the host generates a command setting a condition for flushing the ink nozzles of the inkjet printer, and sends the generated command to the inkjet printer.

  • Patent number: 9868280
    Abstract: A print device includes a head, a recovery portion, and a processor. The head ejects an ink onto a print medium. The recovery portion performs recovery processing to recover an ejection performance of the ink of the head. The processor acquires an integrated value of an ejection amount of the ink, and determines when the integrated value is equal to or more than a reference value, execution of the recovery processing including wiping of a nozzle surface. A nozzle hole is formed in the nozzle surface and ejects the ink. The processor acquires a temperature correlation value corresponding to an environmental temperature, and sets the reference value based on the acquired temperature correlation value such that the reference value when the environmental temperature is a first temperature is smaller than the reference value when the environmental temperature is a second temperature. The second temperature is higher than the first temperature.
