Abstract: A controller of an inkjet printing apparatus is configured to raise a driving voltage to a target voltage, move the cap for an inkjet head from a covering position to a spaced position, and move a carriage, from which the cap is spaced, from a first position to a second position, simultaneously. The controller is further configured to cause the inkjet head to eject the ink toward an ink receiver in response to completion of boosting of the driving voltage and moving of the cap to the spaced position, and cause the conveyer to convey the sheet and cause the inkjet head to eject the ink in accordance with the recording command, in response to receipt of a recording command which instructs recording of an image on the sheet through a communication device, and completion of flushing.
Abstract: Provided herein is a printing apparatus that includes a printhead assembly and a plurality of printhead pressure load modules that are adjustable on a shaft of a printhead pressure load assembly and engaged with a printhead member. The printhead pressure load module has a hollow housing, a plunger member, and a rotary cam. The plunger member and the rotary cam are movably engaged in the hollow housing. The rotary cam includes a plurality of channel members defined at an outer surface. Each channel member has a depth that is different from a depth of an adjacent channel member. A movement of the plunger member inwardly through the hollow housing defines a position of the rotary cam along the longitudinal axis with respect to the hollow housing. Position change of the rotary cam defines a force that acts on a pressure contact member and adjusts a load on the printhead assembly.

Abstract: A head unit control circuit controls a head unit. The head unit includes: an ejector, a determination circuit, and an ejection limit circuit. The injector includes a displaceable piezoelectric element. The piezoelectric element is displaced by changing a drive signal potential. The determination circuit determines whether the piezoelectric element has a predetermined electrical storage capability. The ejection limit circuit stops the drive signal to limit the ejection of the liquid based on the determination. The head unit control circuit supplies an instruction signal, a first designation signal, and a second designation signal to the head unit. The instruction signal instructs the head unit to execute the determination. The determination circuit executes the determination during a period in which the first designation signal is set to a high level, the second designation signal is set to a low level, and the instruction signal is supplied.

Abstract: An inkjet recording apparatus includes an image forming device and a controller. The image forming device includes a recording head unit and forms on paper a fold line image representing a fold line. The controller includes a first selection section. The first selection section selects formation of the fold line image in a “first manner” or a “second manner”. In the “first manner”, the fold line image is formed so as to become invisible after a first period elapses from a first time point at which the fold line image is formed on the paper. In the “second manner”, the fold line image is formed so as not to become invisible even after a second period elapses from the first time point. The second period is longer than the first period.

Abstract: A printing apparatus performing printing by an inkjet scheme includes: an inkjet head; and a controller, configured to control the operation of a main scan driver and a sub scan driver to perform a main scanning operation multiple times on each position on a medium. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controller causes the inkjet head to eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions.
Abstract: A printing apparatus provided with a carriage provided with a mounting unit which can be mounted with a cartridge in which ink is accommodated and a printing head, an ink tank which stores ink, and a control unit which controls ejecting of ink using the printing head, in which, in a case in which the control unit obtains information for blocking ejecting of ink corresponding to the mounting unit, ejecting of ink, by the printing head, corresponding to the mounting unit is blocked.
Abstract: An inkjet printing apparatus includes a head unit including a print head provided with an ejection opening surface for ejecting ink and performing a print operation with respect to a print medium, a platen unit including a platen having a support surface to support the print medium opposite to the ejection opening surface in a case in which the print head performs the print operation, and a spacer member configured to define a print gap between the ejection opening surface and the support surface by abutting against the head unit. A cap member caps the ejection opening surface, and a cap moving unit moves the cap member with respect to the ejection opening surface. In addition, an adjusting member adjusts the print gap by moving the spacer member in association with an operation in which the cap moving unit moves the cap member.
Abstract: In a method for controlling printing elements of an ink print head, an idle time between the ejection of two dots from the same nozzle is determined. In the event that the idle time exceeds a predetermined threshold (?tS), a determined number of vibration cycles is performed (e.g. in immediate succession). The number of vibration cycles is determined based on the idle time, such that more vibration cycles are performed the longer that the idle time lasts between the ejections of two dots from the same nozzle.
