  • Patent number: 11077690
    Abstract: A printing apparatus of this invention scans with a tester a testing chart printed by a printing controller to acquire testing image data. A total amount of displacement calculator calculates an amount of displacement of a recording position including a direction of misregister as a total amount of displacement, based on a large amount of displacement determined by a large amount of displacement determiner, a direction of displacement detected by a direction of displacement detector, a shift amount corresponding to an amount of displacement detecting chart determined by an amount of displacement detecting chart determiner, and a peak position of the amount of displacement detecting chart determined by the amount of displacement detecting chart determining unit. Thus, since a total amount of displacement of the misregister can be calculated only by printing the testing chart on web paper WP, an amount of displacement of the misregister in the transport direction can be obtained easily in a short time.

  • Patent number: 11034156
    Abstract: In an inkjet recording apparatus, ink reserved in a reserve portion flows into a valve chamber through an inflow port. A first outflow port and a second outflow port are capable of flowing the ink from the valve chamber. The first valve element is preliminarily located at an opening position separated from the first outflow port in an inward direction directed from the first outflow port toward inside of the valve chamber. The first valve element is displaced from the opening position to the first outflow port and closes the first outflow port when the valve chamber is filled with the ink. The second valve element is preliminarily located at a closing position closing the second outflow port, and opens the second outflow port when the valve chamber is filled with the ink. Subsequently, a recording head becomes ready to record an image on a recording object with the ink.
