A printer includes: a printhead and a platen positioned below the printhead for supporting print media conveyed along a media feed direction through a print zone. The platen has a particle-collection slot upstream of the print zone relative to the media feed direction and a dam wall at a downstream side of the particle-collection slot. The particle-collection slot and the dam wall extend transversely relative to the media feed direction.

A recording device includes a recording head, a conveyance portion that conveys a liquid-ejected medium so that the liquid-ejected medium passes through a position facing the recording head, a supply portion for air, and an air blowing mechanism that is disposed on an upstream side of the recording head in a relative moving direction between the recording head and the liquid-ejected medium, the air blowing mechanism including an air blow-out port for blowing out air from the supply portion toward a gap between the recording head and the liquid-ejected medium. The air blow-out port includes a plurality of slits that are lined up in a direction intersecting the relative moving direction, and the plurality of slits are lined up in the direction intersecting the relative moving direction so that long sides of the adjacent slits have regions facing each other in a direction orthogonal to the long sides.

A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising an airflow guide structure extending into the opening of the carrier plate, the airflow guide structure configured to flow air at a direction aimed under the printhead and at an oblique angle relative to the movable support surface. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

A printer includes a transport unit, a first head, a second head disposed downstream of the first head, a first suction unit configured to suction ink mist discharged from the first head, a second suction unit configured to suction ink mist discharged from the second head, and a suction device coupled to the first suction unit and the second suction unit, and configured to generate an airflow for suctioning the ink mist, and a first suction device disposed either one of on a first path from the first suction unit to the suction device, and at the suction device, and configured to adjust a flow rate at the first suction unit, and a second suction device disposed either one of on a second path from the second suction unit to the suction device, and at the suction device, and configured to adjust the flow rate at the second suction unit.

The present invention provides an inkjet recording device capable of automatically cleaning the head tip and a cleaning method for inkjet recording apparatus.

An inkjet recording apparatus has a printhead that receives a supply of ink and prints, a main unit that supplies said ink to said printhead, and a cleaning unit that has a cleaning tank into which said entire printhead is inserted and injects a cleaning solution from a cleaning nozzle to said printhead for cleaning. The cleaning unit has a cleaning nozzle that sprays cleaning liquid into the cleaning tank and a cleaning base section that has a housing section that accommodates the tip of the printhead and allows said cleaning liquid to flow into the housing section. The cleaning liquid is allowed to flow into the housing section to clean the tip of the printhead.

A printing apparatus includes a printing unit configured to apply ink containing a coloring material, and a reactive liquid that reacts with the ink, to a printing medium, a reading unit configured to read an ink image on the printing medium, a printing control unit configured to cause the printing unit to print a plurality of ink images different in application amount of the reactive liquid on the printing medium, and a determination unit configured to determine an application amount of the reactive liquid in printing using a predetermined type of printing medium, based on a correlation between a plurality of reading results obtained by the reading unit by reading the plurality of ink images printed on the predetermined type of printing medium.

A liquid discharging device is provided that includes: a first head (11) containing a pretreatment liquid, configured to discharge the pretreatment liquid onto a recording medium; a second head (12) disposed downstream of the first head (11) in a conveyance direction of the recording medium, configured to discharge an ink; an exhaust unit (14) disposed upstream of the first head (11) in the conveyance direction, configured to evacuate a gas present between the first head (11) and the recording medium from a downstream side to an upstream side in the conveyance direction; and a housing (30) internally containing the first head (11) and the second head (12), internally or externally containing the exhaust unit (14), and having an opening (32) downstream of the exhaust unit (14) in the conveyance direction.

In some examples a printing system includes purging manifolds. The printing system includes a fluid ejection device to dispense a fluid and a first reservoir to house a fluid. The system further includes a purging manifold to fluidically couple to the fluid ejection device, and the purging manifold to fluidically couple to the first reservoir. The purging manifold includes a second reservoir. The purging manifold further includes a supply port; a fluid inlet port; and a purging outlet port. The purging outlet port is disposed above the supply port to convey fluid to the first reservoir. The printing system also includes a fluid interface connector to fluidically connect to the supply port and fluidically connect to the fluid ejection device.

A liquid discharge apparatus includes a body and a carriage disposed inside the body. A head is mounted on the carriage. The head discharges ink onto a recording medium and generates ink mist. An ink mist collector includes a fan that generates an air current that circulates in an air flow direction inside the body. A filter collects the ink mist generated by the head. At least one duct adjusts the air flow direction. An encoder is mounted on the carriage. The encoder is disposed downstream from the fan and disposed upstream from the head in the air flow direction.

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 rotating 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.
