Disclosed herein is a print head maintenance cartridge, a printing device and a method of cleaning a print head. The print head maintenance assembly comprises a maintenance cartridge that is movable along a first direction and a wiper assembly comprising a wiper element for wiping a print head. The wiper element extends along the first direction. The maintenance cartridge comprises a guide rail extending along the first direction. The guide rail is to engage with the wiper assembly to adjust a position of the wiper element depending on a relative position between the maintenance cartridge and the wiper assembly in the first direction.

An inkjet recording apparatus includes a nozzle surface, a supply port, a conveyance unit, a first moving device, a cap, a second moving device and a controller. The supply port supplies a cleaning liquid for cleaning the nozzle surface. The cap has a recessed part whose upper surface is opened and a discharge port through which the liquid dropped in the recessed part is discharged. The controller controls the first moving device to arrange the nozzle surface and the conveyance unit in a retreat position, then controls the second moving device to arrange the cap, the nozzle surface and the supply port in a covering position, then controls such that the cleaning liquid is discharged from the supply port to the cap, and then controls such that the ink is purged from the nozzle surface to the cap.

In some examples, a printing press includes a printing unit having at least four nozzle bars, each including a print head. The printing unit includes at least two cleaning devices. At least two of the nozzle bars are configured to make contact with at least one of the cleaning devices. At least one of the cleaning devices has at least one storage position and at least one usage position. In the storage position, the at least one cleaning device is arranged along a transport direction of a printing substrate. The at least two cleaning devices may include at least one guide system configured as a shared guide system, and the at least two cleaning devices may further include at least one guide element configured as a shared guide element. For example, the shared guide element may be configured as at least one of a linear guide or a rail.

A single pass inkjet printer that utilizes a modular printing system with one or more self-contained printing modules, where each printing module is easy to remove and replace from a large printing machine, thus resulting in an overall system that is easy to service and maintain Each module is a self-contained printer including an ink supply, printhead drive electronics, and printhead assembly in order to provide one color or fluid of inkjet printing capability. Each module includes a precise three-point compliant self-aligning mount system to obtain accurate printhead positioning, and a unique integrated printhead tending system that includes a compact movable vacuum knife for cleaning the printheads, and a printhead capping station for sealing and protecting the printheads from the ambient environment when not in use.

A liquid discharge apparatus includes a carriage (1), a liquid discharge head (300, 300C, 300K, 300M, 300Y, 300S, 300W) having a discharge port (P1, P2), a first driver (92), and a second driver (93). The carriage is movable along at least one of a first axis (X) and a second axis (Y) intersecting the first axis. The liquid discharge head is held by the carriage and discharges a liquid from the discharge port toward an object (100) in a direction along a third axis (Z) intersecting the first axis and the second axis. The first driver moves the carriage along the third axis. The second driver moves the liquid discharge head along the third axis relative to the carriage.

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 recording portion has a nozzle surface. A first movement portion moves the recording portion in a first direction intersecting the nozzle surface. A second movement portion moves a first maintenance portion in a second direction along the nozzle surface. The recording portion is movable to a recording position at which recording is performed on a medium, and a first retreated position where the recording portion is retreated from the recording position. The first maintenance portion is movable to a maintenance position at which maintenance of the nozzle surface is performed and a second retreated position retreated from the maintenance position. When an error occurs, a control portion causes the recording portion to retreat away from the first maintenance portion in a first direction. Then, the first maintenance portion is caused to retreat in a second direction.

A printer includes a head having a nozzle face which ejects ink toward an object, a driving mechanism which moves the head in a first direction and a second direction approximately orthogonal to the first direction, a nozzle cap movable between a first position where the nozzle face is capped and a second position where the nozzle face is uncapped, and a lock mechanism which regulates movement of the head in the first direction and the second direction in the state where the nozzle cap is in the first position.

A liquid ejecting apparatus including a transporting portion that transports a medium along a transport path, a liquid ejecting head that performs recording by ejecting, through a nozzle, a liquid onto the medium that is being transported, a mounting portion in which a liquid storage portion that stores the liquid supplied to the liquid ejecting head is mounted, and a heating portion that heats the medium on which the recording has been performed. The transport path includes an upper path positioned above the mounting portion in a vertical direction. After transporting and passing the medium, on which the recording has been performed, through the upper path, the transporting portion discharges the medium through a discharge port. The heating portion is provided above the mounting portion in the vertical direction and heats the medium transported through the upper path.
