Abstract: A liquid discharge apparatus includes a head configured and arranged to discharge a liquid including a sedimentary substance, and a liquid supply path for supplying the liquid from a liquid tank where the liquid is retained to the head. The liquid supply path has differences in elevation of a predetermined length or more in a vertical direction. The liquid supply path has a portion formed into a stepped shape and an angle formed by a width portion and a height portion in the portion formed into the stepped shape is 45 degrees or more and 90 degrees or less.

Abstract: A liquid discharging apparatus, which discharges liquid from a nozzle of a liquid discharging head on the basis of data, includes a controller and a member. When the controller is in a standby state where the liquid is not discharged from the nozzle on the basis of the data or after the controller has received a power OFF instruction, the controller performs a drawing operation in which the liquid is drawn to a side opposite to a discharge direction in which the liquid is discharged so as to at least form a space at a distal end portion of the nozzle. After the controller has performed the drawing operation, the member covers an opening of the nozzle.
