Abstract: A liquid ejecting device includes a plurality of liquid ejecting heads reciprocally movable in a main scanning direction and arrayed in the main scanning direction. Each of the plurality of liquid ejecting heads include a liquid ejecting portion configured to eject liquid. The plurality of liquid ejecting heads includes: a first endmost liquid ejecting head; and a second endmost liquid ejecting head. The first endmost liquid ejecting head constitutes one end in the main scanning direction of the plurality of liquid ejecting heads. The second endmost liquid ejecting head constitutes another end in the main scanning direction of the plurality of liquid ejecting heads. The liquid ejecting portion of at least one of the first endmost liquid ejecting head and the second endmost liquid ejecting head is disposed at a position deviated toward the remaining one of the first endmost liquid ejecting head and the second endmost liquid ejecting head.

Abstract: A liquid discharging device including a liquid discharging head with nozzles, a carriage, and a controller is provided. When a position of the end of a sheet is on an inner side of an outmost contact part among a plurality of contact parts along a scanning direction, the controller determines discharging timings to discharge liquid from the nozzles based on first gap information, which is related to a gap between the sheet and the liquid discharging surface and is stored in a gap information storage. When the position of the end of the sheet is on the inner side of the outmost contact part, the controller determines the discharging timings based on the first gap information stored in the gap information storage and on second gap information generated in a gap information generating process.

Abstract: A first cover moves between a first closed position and a first open position. The first cover is located at another end of a housing when the first cover is located at the first closed position. A second cover moves between a second closed position and a second open position. The second cover is located closer to one end than the first cover is at the first closed position and at the second closed position. A first portion of a first conveyance path is formed between the first cover and the second cover at the first closed position and at the second closed position. A second portion of a second conveyance path is formed at a side of the second cover facing the one end at the second closed position. When the first cover opens the first portion, the second cover is located at the second closed position.

Abstract: A replenishing-type liquid storage tank includes a tank body, a backpressure application member, and upper limit indicator set in the tank body. Liquid is replenishable in the tank body and the tank body is configured to store the liquid therein. The backpressure application member is made from a material capable of absorbing liquid and is accommodated in the tank body to apply backpressure to the liquid stored in the tank body. The upper limit indicator is indicative of a liquid level of a maximum tolerable amount of the liquid that can be stored in the tank body. The backpressure application member has a portion positioned higher than the upper limit indicator.

Abstract: There is provided a liquid jetting apparatus including a conveyor, a liquid jet head, a carriage, a carriage moving device, and a controller. The controller carries out printing by repeating a scan-printing operation and a conveyance operation, and carries out a process of determining a jet-timing such that the jet-timing and a predetermined reference timing may deviate oppositely from each other between a print area on the upstream side and a print area on the downstream side along a scanning direction for the carriage to move in the scan-printing operation with respect to a predetermined reference position in the scanning direction, based on a value of a correction parameter. The correction parameter is set to the same value for nozzles included in an identical one of nozzle groups and to different values for the corresponding nozzles included in different ones of the nozzle groups.

Abstract: A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.
