A recording apparatus includes a recording head capable of moving back and forth relative to a recording medium and ejecting a liquid from a nozzle, a cover portion that covers at least a portion of a no-nozzle-formed region in which the nozzle is not formed within a nozzle-formed surface in which the nozzle is formed, and a wiper provided in a back-and-forth movement range of the recording head and capable of wiping the cover portion without contacting the nozzle-formed surface as the recording head moves back and forth.

A liquid ejecting device includes a base portion, a liquid ejecting portion movably provided at the base portion, a medium supporting portion provided at the base portion and configured to support a printing medium in a printing region where the liquid ejecting portion performs printing, and a maintenance portion disposed in a region on the +X direction side of the printing region in the X-axis direction in the base portion. The maintenance portion includes a moisturizing portion that can form a closed space to which nozzle opens, a cleaning portion that can forcibly discharge liquid from the nozzle, and a wiper that can wipe a nozzle surface where the nozzle is provided. The moisturizing portion, the cleaning portion and the wiper are disposed side by side in the Y-axis direction.

A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle that is disposed on a nozzle surface, a first wiping portion which is able to wipe away the liquid that is adhered to the nozzle surface, and a second wiping portion which is able to hold the liquid that is adhered to the nozzle surface by contacting the nozzle surface, wherein it is possible to perform a first maintenance operation in which the nozzle surface is wiped using the first wiping portion and a second maintenance operation in which the second wiping portion is caused to contact the nozzle surface due to the second wiping portion being biased by the first wiping portion.

An image forming apparatus includes a conveyance part, a head unit, a distance changing part, three blocks and three pins. The distance changing part moves the head unit between a printing position where a printing operation is performed and a retreat position separated away from the conveyance part farther than the printing position. The three blocks are provided in one of the conveyance part and the head unit at intervals in the conveyance direction and a width direction crossing the conveyance direction. The three pins are provided in the other of the conveyance part and the head unit at positions facing the three blocks. Each of the three blocks has a positioning groove having a pair of inclined surfaces. The pins come into two-point contact with the inclined surfaces of the blocks in a state where the head unit is positioned in the printing position.

A single-pass inkjet printer contains a track for guiding a printing medium in the Y direction, a plurality of printing head modules which are arranged one behind the other in the Y direction and a respective plurality of printing heads which extends in the X direction transversely over the track, and a printing region in which the printing head modules can be mounted in a respective printing position in an upright manner in the Z direction and in a reversibly insertable and removable manner along the Z direction. The single-pass inkjet printer further contains a storage region in which a number of printing head modules are mounted in a storage position in an upright manner substantially in the Z direction and in a reversibly insertable and removable manner along the Z direction. The printing heads of printing head modules set in the storage position are received in a protective cover.

An inkjet printing apparatus includes: a print bar unit having a print bar, a maintainer, and a movement driver; and a controller. Upon maintenance of an inkjet head of the print bar, the controller is configured to drive the movement driver to move the maintainer from a deployment position to a retreat position with the print bar arranged at a maintenance position above a height position for printing while wiping a nozzle surface of the inkjet head with the wiper of the maintainer being moved. The deployment position is a position under the inkjet head in maintenance of the inkjet head and the retreat position is a position where the maintainer is retreated from the deployment position.

An inkjet printing apparatus includes: a print bar unit including an inkjet head configured to eject ink to a web being conveyed; and a guide configured to guide movement of the print bar unit in a print bar movement direction intersecting a conveyance direction of the web between a first position, a second position, and a third position. The first position is a position where the print bar unit performs printing on the web. The second position and third position are located on one and the other sides of the first position in the print bar movement direction.

A printing apparatus includes: a flushing determination unit, and a storage unit, wherein the flushing determination unit is configured to: calculate a temporary return position, a temporary reciprocating movement time that is necessary when the carriage is returned at the temporary return position, and a threshold value that is a longest non-ejection time during which printing can be performed in a stable manner at an environmental temperature measured by a thermometer, based on print data to be printed in reciprocating movement of the carriage; and determine whether the temporary reciprocating movement time exceeds the threshold value, wherein when the temporary reciprocating movement time exceeds the threshold value, the flushing determination unit sets a position at which the one reciprocating movement time becomes longer than the temporary reciprocating movement time as a return position in the reciprocating movement, and determines to perform the flushing in a return path.

There is provided a liquid discharge device including: a wiping member that performs wiping on a nozzle forming surface by being caused to perform relative movement on the nozzle forming surface while coming into contact with the nozzle forming surface; a cleaning liquid supply section that supplies cleaning liquid to at least one of a head and the wiping member; and a circulation speed adjustment section that is capable of adjusting a circulation speed of the liquid, which is circulated between a liquid storage section and the head, to a second speed which is faster than the first speed. In addition, the circulation speed during the wiping is the second speed.

A maintenance device includes a plurality of heads that discharges liquid for printing. A cleaner selectively cleans the heads. A cleaning controller controls the cleaner. A determiner determines a cleaning time when the cleaner cleans one of the heads. An interruption-resumption controller controls the heads to interrupt printing at the cleaning time and resume printing when the cleaner finishes cleaning the one of the heads. The cleaning controller controls the cleaner to clean the one of the heads whenever the interruption-resumption controller controls the heads to interrupt printing at the cleaning time.
