A conveyance device includes a conveyor having an outer face that contacts a sheet adhered with liquid. The conveyor conveys the sheet. A heat radiator generates air. A ventilator sends the air to the outer face of the conveyor.

A printing machine includes an inkjet printing head having separately controllable nozzles for applying ink to a transported printing material, a radiation drier having radiation sources for generating electromagnetic radiation to at least partly dry and/or cure the applied ink on the transported printing material and at least one light trap disposed between the inkjet printing head and the radiation drier in such a way that the light trap forms a barrier for reflected and/or scattered radiation, thus protecting the inkjet printing head from radiation. The light trap includes at least one channel connected to an aspiration device for aspirating contaminated ambient air through the channel and reducing or preventing contamination of the radiation drier.

In some examples, a convective gas bar can include a gas inlet to receive supply gas to a first portion of the convective gas bar, feed holes located in the first portion, a nozzle plate located in a second portion of the convective gas bar, where the nozzle plate includes nozzles, and the nozzles are adapted to receive and direct the supply gas from the feed holes through the nozzles.

An image forming apparatus includes a housing, a sheet conveyor, a sheet stacker, and circuitry. The sheet conveyor is configured to convey a sheet on which liquid is applied. The sheet stacker is configured to stack the sheet conveyed by the sheet conveyor. The circuitry is configured to control conveyance of the sheet. The circuitry is configured to cause the sheet conveyor to expose the sheet on which the liquid is applied, to an outside of the housing, and convey the sheet to the sheet stacker.

A dryer includes a first airflow generator configured to generate a first airflow to be blown to a sheet conveyed in the blower, a second airflow generator configured to generate a second airflow to exhaust air in the blower outside the blower, and circuitry configured to control the first airflow generator and the second airflow generator to control a blowing amount of the first airflow and an exhaust amount of the second airflow according to a type of the sheet.

A printer includes an ejecting head that ejects ink, a glued belt including a support surface, a first fan and a second fan configured to blow air toward the support surface, and a facing portion facing a portion of the first fan and a portion of the second fan. The facing portion includes an opening that opens in the Z direction. The opening is located between the first fan and the second fan in the X direction when viewed in the Z direction. When a spacing in the X direction at a first position in the +Y direction is defined as the first spacing and a spacing in the X direction at a second position upstream of the first position in the +Y direction is defined as the second spacing, the second spacing is larger than the first spacing.

A recording system includes a recording device including a recording unit configured to perform recording, and a drying device including a drying mechanism. The recording device includes a support surface configured to support the recording medium and provided downstream of the recording unit in the conveyance direction, the device is configured to be mounted on the recording device at a position where the support surface and the drying mechanism face each other, one of the recording device and the drying device includes a setting member configured to set a spacing between the support surface and the drying mechanism to a predetermined spacing when the drying device is mounted on the recording device, the drying mechanism functions when the spacing is set to the predetermined spacing by the setting member, and a function of the drying mechanism stops when the setting by the setting member is released.

Provided are a drying device, a liquid applying system, and a printing system that suppress an increase in size in a direction facing a substrate transport surface.

A drying device that blows a heated gas to a substrate transport surface in a substrate transport path includes a blowing unit provided with a jetting port formed in a first surface facing the substrate transport surface, a heat source, and a fan motor that blows a gas to the heat source to generate the heated gas. A heated gas inflow port through which the heated gas is supplied is formed in a second surface of the blowing unit, the second surface intersecting the first surface.

Provided are a blowing unit, a drying device, a liquid applying system, and a printing system with which it is possible to realize uniformly blowing air via a plurality of jetting ports.

In a blowing unit that has a hollow structure and blows air via a plurality of jetting ports disposed at a first surface, a gas inflow port through which a gas supplied from a gas supply source flows in is formed in a second surface which intersects the first surface and at which the jetting ports are not disposed and a ratio of a sum of opening areas of the plurality of jetting ports to an opening area of the gas inflow port is equal to or larger than 0.1 and equal to or smaller than 1.0.

A heating device includes a blower configured to blow air, the blower comprising a channel member defining a channel of the air, and a heater disposed outside the channel member. The channel member has end portions and a central portion in a longitudinal direction, each of the end portions having higher heat absorption property than the central portion, and said each of end portions of the channel member faces the heater.
