  • Patent number: 11407219
    Abstract: A liquid discharge apparatus includes a head to discharge a liquid containing a solvent from a discharge port toward an object, a concentration detector to detect a vapor concentration of the solvent, and circuitry to causes the head to discharge the liquid from the discharge port while moving the discharge port of the head in a movement direction perpendicular to a discharge direction to discharge the liquid. When the vaper concentration is equal to or higher than a first threshold, the circuitry stops moving the head in the movement direction and causes the head to stop discharging the liquid from the discharge port. When the vaper concentration is less than a second threshold, the circuitry resumes moving the head in the movement direction from a stop position where the head stops moving in the movement direction and causes the head to resume discharging the liquid from the discharge port.

  • Patent number: 11400705
    Abstract: In a liquid ejection apparatus, a controller of the liquid ejection apparatus is configured to, in response to receiving a recording instruction to instruct the liquid ejection apparatus to perform image recording on a recording medium, perform ejection inspection to determine whether liquid is ejected from each nozzle of a liquid ejection head toward an electrode based on a signal outputted from a signal output circuit. For the ejection inspection, the controller is configured to control a voltage applying circuit to apply an inspection voltage between the electrode and the liquid ejection head. In response to detecting that a leakage current greater than a predetermined value flows between the electrode and the liquid ejection head, the controller is configured to cancel the ejection inspection and control a voltage applying circuit to apply a reverse voltage opposite in polarity to the inspection voltage between the electrode and the liquid ejection head.
