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.

Embodiments described herein relate to an inkjet service station and methods of servicing an inkjet printer with the inkjet service station. The inkjet service station is disposed in an inkjet printer of an inkjet chamber. The inkjet service station is operable to perform servicing operations on a processing apparatus of the inkjet printer. The servicing operations include at least one of printhead spitting, printhead purging, printhead flushing, printhead cleaning, printhead drying, or vacuum suction.

An ink jet recording apparatus includes an ink container in which ink to be used to perform printing on a print target is stored, a nozzle which is connected to the ink container and from which pressurized and supplied ink is jetted, charging electrodes that charge ink particles jetted from the nozzle with electricity, deflecting electrodes that polarize the ink particles charged with electricity by the charging electrodes, a gutter that recovers ink not used for printing, a solvent container in which a solvent is stored, and a liquid nozzle which is connected to the solvent container and from which a pressurized and supplied solvent is jetted. The liquid nozzle includes a liquid flow passage portion that extends from the nozzle in a direction of the gutter, and a liquid jet hole that is formed at an angle allowing the pressurized and supplied solvent to hit the nozzle through the liquid flow passage portion.

An ink-jet printer includes: a base material transport mechanism for transporting a base material along a transport path in a transport direction; an ink ejection head having a lower surface opposed to the transport path, and an ink ejection port for ejecting ink toward the transport path; and a base plate having a lower surface opposed to the transport path over the transport path, and a mounting hole open in the lower surface, the ink ejection head being mounted in the mounting hole. The base plate includes an air flow hole that is a though hole penetrating through the base plate. The air flow hole has an air outlet open in a location downstream of the ink ejection port in the lower surface. Air passing through the air flow hole is ejected from the air outlet toward the transport path.

A gas collection device of a printing press includes an organic compound treatment system (33) including a gas chamber (34). The device includes a cover (3) configured to cover a print unit (2) of a printing press. The device includes a gas transfer device (4) configured to suck a gas of a volatile organic compound produced in the print unit (2) from the inside of the cover 3 and transfer the gas to the gas chamber (34). It is possible to provide a gas collection device of a printing press, which can prevent a work environment in which the printing press is installed from being deteriorated by the gas of the volatile organic compound.

A printing apparatus includes a platen that supports a recording medium, a printing head that reciprocates along the platen, and discharges a droplet onto the recording medium supported by the platen at least in a forward route or a backward route of the reciprocation, to perform printing, and an air blowing unit disposed on at least one of two sides of the platen in a reciprocation direction, that is a direction in which the printing head moves along with the reciprocation, and blows an airflow to a nozzle surface of the printing head that reciprocates.

A printhead servicing system comprises a humidified air stream generator (10) to generate a humidified air stream; a humidified air stream channelling module (20) to channel the generated humidified air stream to a humidified air stream ejection module (30) to eject the humidified air stream towards a printhead nozzle plate (52a) of a printer (50); and a wiping module (40) to wipe a printhead nozzle plate (52a) of the printer.

Disclosed is an inkjet head cleaning device comprising: a body; an ejection part formed in the body, and configured to eject a cleaning liquid to a nozzle surface of a head; and, a suction part formed in the body, and configured to suck the cleaning liquid ejected from the ejection part and used for cleaning the nozzle surface of the head, and foreign substances separated from the nozzle surface of the head; and wherein the ejection part comprises, a perpendicular passage through which the cleaning liquid flows and a discharge end at the end of the perpendicular passage and configured to guide the cleaning liquid to eject toward the suction part.

A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.
