An ink maintenance system for a printer comprising a first tray having a base and a plurality of side walls, the first tray having a first length and an open top along the length and a second tray having a base and a plurality of side walls, the second tray having a second length and an open top along its length. The system also includes a fan and a filter. To use the system, a print head is positioned in a standby or cleaning position within the printer and ink is ejected from one or more print nozzles into an ink maintenance system within the printer such that the ejected ink is collected in at least one of a catch tray or a filter of the ink maintenance system. The system is then removable from the printer for cleaning.

A printer and corresponding method of printing an image on a surface of a plurality of food products by providing a system having a printer with an extendable and retractable receiving arm and a movable food product delivery tray for continuously and automatically providing delivery of unprinted food products which are retracted into the printer, printed on, and returned by the receiving arm to the rotatable delivery tray and the tray further moves to deliver subsequent food products for printing. A motorized base spaced apart from the printer supports the delivery tray during and printing processes.

The disclosure relates to a printer device configured for a packaging machine as a thermal inkjet printer. The printer device includes a frame and a printhead holder mounted thereon and configured to support a replaceable printhead. The printhead holder has an opening for at least one nozzle formed on the printhead. The printer device further includes a sealing unit and a lifting mechanism for the sealing unit, by means of which the sealing unit is adjustable between a first position, in which the sealing unit exposes the opening of the printhead holder, and a second position, in which the sealing unit closes the opening of the printhead holder. Furthermore, the disclosure relates to a wet cleaning process of a printer device.

A recording device includes: a storage unit configured to store a medium, a recording unit configured to dispense a liquid droplet onto the medium transported from the storage unit to perform recording, a discharge unit configured to discharge the medium on which recording was performed and an imaging unit disposed on a transport path running from the storage unit, past the recording unit, to the discharge unit, the imaging unit being configured to capture an image of the medium on which recording was performed, where a restricting wall narrowing a space above the medium on the transport path is provided between the recording unit and the imaging unit.

A mist collector includes: a nozzle through which air is sucked from a suction port and discharged from a discharge port; and a cyclone including an outer cylinder and an inner cylinder. The inner cylinder includes an intake hole and forms an airflow inside the inner cylinder by air taken therein through this intake hole, thereby separating ink mist from the air.

Provided is an evacuation device for an inkjet printing device that is designed to guide a printed recording medium along a transport direction through a constriction with an opposite gas flow, in order to be able to efficiently and comprehensively evacuate ink vapor before the constriction, in terms of the transport direction.

The present disclosure relates to a device for climate control of an interior of a machine in a food and beverage industry. The device includes an air discharge system for discharging air from the interior of the machine. The air discharge system includes a first air extraction duct configured for first selective extraction of contaminated air or second selective extraction of high-temperature air or at least two separate air extraction ducts including a first air extraction duct configured for the first selective extraction of the contaminated air and a second air extraction duct configured for the second selective extraction of the high-temperature air. The device further includes an air supply system for supplying air to the interior of the machine. The supplied air includes at least one of fresh air or purified extracted air.

Systems and methods for industrial printing, e.g., using drop-on-demand (DOD) inkjet print heads, include, in at least one aspect, a printing device including: a print head including a print engine, including multiple nozzles, and circuitry to selectively eject ink through the multiple nozzles to form an image on a moving substrate, and to purge the ink through the multiple nozzles; and a printhead enclosure having an opening in front of the multiple nozzles to allow the selectively ejected ink to pass through the opening when the selectively ejected ink is ejected toward the moving substrate; wherein the printhead enclosure includes a hole placed away from the multiple nozzles; and wherein the printhead enclosure is configured to direct the ink that is purged through the multiple nozzles along an inside surface of the printhead enclosure to the hole through which the ink flows and exits the printhead enclosure.

A printing device includes a head and a carriage. The head has a nozzle. The head is configured to eject liquid from the nozzle toward a printing medium. The carriage is configured to move the head in a first direction. The carriage includes a first distance sensor. The first distance sensor is configured to measure a distance between the head and the printing medium. The first distance sensor is a specular reflection type distance sensor. The first distance sensor includes a light-emitting element and a light-receiving element. The light-emitting element and the light-receiving element are aligned in the first direction.

Disclosed herein is a device, a printing device and a method of operating a printing device. The device comprises an air flow path extending from an intake to an outlet. The intake is to be mounted in a printing device and comprises a proximal intake segment and a distal intake segment along the air flow path. A proximal air flow path from the proximal intake segment to the outlet is shorter than a distal air flow path from the distal intake segment to the outlet. Each of the proximal and distal intake segments comprises a wall segment with at least one hole. An opening ratio of an area of the at least one hole and an area of the respective wall segment is larger in the distal intake segment than in the proximal intake segment.
