A printing apparatus includes a head including a plurality of nozzles configured to discharge liquid to a medium, an abnormal nozzle detection unit configured to detect an abnormal nozzle having a discharging defect among the plurality of nozzles, a contact detection unit configured to detect contact between the head and the medium, a suction unit configured to perform an ejection operation of ejecting the liquid from the plurality of nozzles, and a control unit. The control unit executes a suction operation when the abnormal nozzle is detected and the contact between the head and the medium is detected, and the control unit executes a printing of complementing the abnormal nozzle when the abnormal nozzle is detected and the contact between the head and the medium is not detected.

There is provided a liquid discharge apparatus including a head configured to eject a liquid from nozzles being open in a nozzle surface, a liquid absorbing wiper, and a support supporting the liquid absorbing wiper. The supporter is movable relative to the head, between a first position where the liquid absorbing wiper is in contact with the nozzle surface, and a second position where the liquid absorbing wiper is away from the nozzle surface, the supporter has a flow channel for a liquid cleaner to flow therethrough, and the liquid absorbing wiper sucks in the liquid cleaner from below by way of contact with the liquid cleaner flowing in the flow channel.

Provided is a liquid ejection apparatus which, in a case of performing wiping operations at a plurality of different wiping pressures, can perform each wiping operation at a suitable wiping pressure and a suitable angle. To achieve this object, a liquid ejection apparatus is configured such that the angle of the wiping surface of a wiper to an ejection port surface can be changed while the wiper is out of contact with the ejection port surface and is not performing wiping, and the ejection port surface can be wiped with the wiper after the wiping surface angle is changed.

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 head cap configured to maintain a head configured to discharge a liquid from nozzles formed in a nozzle surface, the head cap includes a cap configured to cap the nozzle surface of the head, and a holder holding the cap, the holder being detachably attachable to one of a carriage mounting the head and a guide configured to guide the carriage.

A channel member of a liquid ejection head includes an ejection surface, an outer peripheral surface that is connected to an outer edge of the ejection surface and that faces outside of the ejection surface in a direction along the ejection surface, and a plurality of ejection holes that open in the ejection surface. The channel member includes a plurality of concave portions in the outer edge of the ejection surface, the plurality of concave portions being recessed in the ejection surface and being recessed in the outer peripheral surface. With the configuration, it is possible to collect, in the concave portions, a liquid (such as ink mist) that has leaked out from the ejection holes.

Examples for of a floating printhead shield for a printing device are described herein. In some examples, a printhead shield may be located between a printhead and a print zone. When in a printing position the printhead shield may engage the printhead. When in a retracted position the printhead shield may separate from the printhead.

The liquid ejection apparatus includes a liquid ejection head, a cap having a closed space forming section forming a closed space, an inflow port through which a humidification fluid flows in, and an outflow port through which the humidification fluid flows out, a humidification fluid storage section storing the humidification fluid, a supply flow path communicating the humidification fluid storage section with the inflow port, a collection flow path communicating the humidification fluid storage section with the outflow port, a pump, a moisture supply section, and a controller. One end of the collection flow path opens at a position in the humidification fluid storage section that is lower than a liquid surface of the humidification fluid. The controller causes the moisture supply section to supply water into the circulation path and drives the pump to cause the humidification fluid to flow in the circulation path.

Present examples relate to fluid ejection peripherals for, non-limiting example, ink jet peripherals. More specifically, but without limitation, present examples relate to caps for fluid ejection peripherals which may be locked or unlocked relative to the peripheral device.

A liquid receiving device includes a liquid receiving portion configured to receive a liquid ejected from a liquid ejecting portion via an opening portion, a first discharge flow path configured to discharge the liquid in the liquid receiving portion, and a second discharge flow path configured to discharge the liquid in the liquid receiving portion. The liquid receiving portion includes an absorbing member, a first communication portion that has a first discharge port open to an inside of the liquid receiving portion, and a second communication portion that has a second discharge port open to an inside of the liquid receiving portion, the first communication portion is provided at a position where the first discharge port is in contact with the absorbing member, and the second communication portion is provided at a position where the second discharge port is not in contact with the absorbing member.
