摘要： An inkjet printing apparatus includes a transport speed detector for detecting transport speed of a printing medium, an inkjet head having a plurality of discharge portions for discharging ink droplets from the discharge portions for printing, and a flushing controller for carrying out discrete flushing from the discharge portions. For an acceleration area of the printing medium where the transport speed detector detects an increase in transport speed before printing, a first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing. For a constant speed area of the printing medium where the transport speed detector detects a substantially constant transport speed during printing, a second discharge rate lower than the first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing.

摘要： A nozzle arrangement has nozzle arrays arranged in a first direction. Liquid passages are interconnected via a communication path and arranged in the first direction. Nozzles in each one of the nozzle arrays are connected to a corresponding one of the liquid passages. Each of the liquid passages has a first end connected to a supply port and a second end connected to the communication path, in a second direction. The controller controls a flushing operation ejecting liquid from the nozzles as waste liquid. The controller controls the head portion to perform a selective flushing operation. The selective flushing operation is an operation of ejecting the liquid from the nozzles corresponding to a part, being at least one of the liquid passages, of a set of liquid passages while stopping ejection of the liquid from the nozzles corresponding to a remaining part of the set of liquid passages.

摘要： A droplet ejecting apparatus includes a liquid filling chamber filled with a liquid, and a plurality of pressure chambers in communication with the liquid filling chamber and filled with the liquid. Each of the pressure chambers includes a communication port in communication with the liquid filling chamber, a pressure generating element for exerting pressure on the liquid which fills the interior of each pressure chamber, and a nozzle for ejecting the liquid in each pressure chamber therefrom in the form of droplets. A recovery controller brings the pressure generating element corresponding to the communication port included in a partial region of the liquid filling chamber into operation to cause the corresponding nozzle to eject the droplets. This produces a flow of the liquid directed toward the partial region in the liquid filling chamber to efficiently diffuse precipitable ingredients accumulating in the liquid filling chamber, thereby efficiently eliminating the accumulation of the precipitable ingredients in the liquid filling chamber in communication with the pressure chambers.

摘要： An inkjet printer is operated to print an ink image and clear inkjets simultaneously. The inkjet printer delivers to a first inkjet in a printhead a first signal that ejects an ink drop from the first inkjet that corresponds to a pixel of an ink image stored in a memory of the printer and delivers to at least one other inkjet in the printhead a second signal that ejects an ink drop from the at least one other inkjet that does not correspond to a pixel of the ink image stored in the memory of the printer.

摘要： A recording head includes an ink-discharging surface and nozzles. The ink-discharging surface is provided with ink-discharging ports of the nozzles. A light-emitting element and a light-receiving element are disposed opposite each other close to the ink-discharging surface. The light-receiving element outputs a detection signal. A reflector is provided on the ink-discharging surface and reflects light emitted from the light-emitting element toward the light-receiving element. One of the nozzles is driven and whether the nozzle discharges an ink drop is checked on the basis of change in the detection signal due to interception of the reflected light by the ink drop. If the nozzle discharges an ink drop, then whether the nozzle discharges the ink drop in an appropriate direction is checked on the basis of change in the detection signal due to interception of the direct light by the ink drop.
