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.

Image recording apparatus

A replenishing-type liquid storage tank includes a tank body, and a backpressure application member. Liquid is replenishable in the tank body and the tank body is configured to store the liquid therein. The backpressure application member is accommodated in the tank body to apply backpressure to the liquid stored in the tank body. The backpressure application member has a portion positioned equal to or higher than a liquid level of a maximum tolerable amount of the liquid storable in the tank body.

A replenishing-type liquid storage tank includes a tank body, and a backpressure application member. Liquid is replenishable in the tank body and the tank body is configured to store the liquid therein. The backpressure application member is accommodated in the tank body to apply backpressure to the liquid stored in the tank body. The backpressure application member has a lower end positioned at a height equal to or lower than a liquid level of a minimum amount of liquid required to be stored in the tank body for enabling the backpressure application member to apply backpressure to the liquid stored in the tank body.

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.

An image forming apparatus includes a casing having a front end and a rear end, a first tray, a first print engine, a second tray, a second print engine and a controller. The controller configured to perform: receiving first image data representing the first image and second image data representing the second image; executing a first process including a first conveying process and a first recording process; executing a second process including a second conveying process and a second recording process; determining whether an error has occurred in the second process; and in a case where the error has occurred in the second process, stopping the second process while continuing the first process.

A printer includes a head having nozzles, a carriage with the head mounted thereon, a carriage motor to move the carriage along a scanning direction, an encoder including a scale having reference marks formed thereon along a particular direction, and a sensor to detect the reference marks while moving relative to the scale along with movement of the carriage along the scanning direction, and a controller configured to perform liquid discharging to control the head to discharge liquid from the nozzles toward a recording medium while performing feedback control of the carriage motor based on velocity information such that the carriage moves at a target velocity along the scanning direction, the velocity information representing a carriage velocity based on detection results of the sensor, and interrupt the liquid discharging when the carriage velocity exceeds an overshoot threshold higher than the target velocity during the liquid discharging.

Printer and method for preventing erroneous interruption of printing

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.

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.

A liquid ejection device includes an ejection head having a plurality of nozzle groups, each of the plurality of nozzle groups including one nozzle or two or more nozzles arranged adjacent to each other, and a controller configured to determine an ejection timing each of the plurality of nozzle groups such that a first deviation amount in the main scanning direction between an first image and an second image on an medium is smaller than a second deviation amount in a main scanning direction between an area to be printed by an first nozzle group included the plurality of nozzle groups and an area to be printed by an second nozzle group adjacent to the first nozzle group.

Liquid ejection device

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.

Liquid discharging device

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.
