  • Patent number: 11141989
    Abstract: An electrohydrodynamic (EHD) jet printing apparatus or system may include circulation of printing fluid to minimize or eliminate clogging in a nozzle. An exemplary nozzle comprises at least two ink channels—one allowing flow to a droplet emitting opening and one allowing flow away from the droplet emitting opening—configured for circulating ink. The nozzle may transfer ink to a substrate with an EHD technique involving voltage or current modulation. For example, an electric field may be applied between the nozzle and printing substrate such that the ink meniscus changes shape and releases ink from the tip of the liquid cone. A multi-channel nozzle may take a variety of configurations, including two co-axially aligned capillaries, side-by-side parallel capillaries, or capillaries arranged at an angle with respect to one another but converging at a single point where the conical meniscus is formed.

  • Patent number: 11142424
    Abstract: A sheet conveying apparatus includes a sheet conveying path, conveying members, a switching unit, a receiving unit, and a control unit. The sheet conveying path includes a first conveying path and a second conveying path having a conveying load for a sheet larger than the first conveying path. The switching unit selectively switches the sheet conveying path between the first conveying path and the second conveying path. The control unit determines whether the sheets are first sheets or second sheets thicker than the first sheets, based on sheet thickness information received by the receiving unit. If the sheets are the first sheets, the switching unit switches the sheet conveying path between the first conveying path and the second conveying path alternately. If the sheets are the second sheets, the switching unit switches to fix the sheet conveying path to the first conveying path.

  • Patent number: 11124005
    Abstract: With a conventional method of estimating an application amount of a clear recording material from a color of a patch, it is difficult to realize high accuracy, similar colors are sometimes exhibited in measurement results even if there is a significant difference in the application amount of a clear ink. In contrast, with a disclosed configuration of estimating an application amount of a clear recording material from a reflection intensity of a patch, measurement results that exhibit a one-dimensional increase of a relationship between the application amount of the clear recording material and the reflection intensity are acquired, so that the accuracy of application amount estimation increases.
