A document carrier device is provided for supporting and transporting a document in a document processing system. The device includes a workpiece carrier having a support surface for receiving a document; a heating device having a heat conducting element for transferring heat generated; and an actuator for causing relative movement between the heat conducting element and the workpiece carrier to change between a first mode of operation and a second mode of operation. In the first mode of operation, the heat conducting element extends, without thereby being in mechanical contact with the workpiece carrier, through one or more recesses in the workpiece carrier in the region of the support surface to be able to transfer heat generated by the heating device, at least in part, to a document received. In the second mode of operation, the heat conducting element has a distance from the support surface which is increased.

A fixer includes a fixing roller around which a recording medium is directed such that the print image to be fixed faces toward the shell surface of the fixing roller. A fixing gap is generated with a gaseous fixing medium between the shell surface of the fixing roller and the recording medium. This advantageously produces an efficient and gentle fixing of the print image.

A heating device heats a sheet to which a liquid discharge unit discharges a liquid. The heating device includes a first heater to heat the sheet that has passed through the liquid discharge unit, a vacuum conveyor to convey the sheet that has passed through the first heater while sucking the sheet, a second heater to heat the sheet being conveyed by the vacuum conveyor, and circuitry that cause the first heater to heat the sheet when sheet data regarding the sheet satisfies a predetermined condition.

Both stability and high glossiness of a glossy ink used for printing can be achieved. A printer is provided that performs inkjet printing for a medium. The printer includes a glossy ink head as an inkjet head that discharges droplets of a glossy ink, a heater, and an ultraviolet light source. The glossy ink includes an ultraviolet-curable resin curable by being irradiated with ultraviolet light, a glossy pigment, and a solvent added to disperse the pigment. Particles of the glossy pigment have particle sizes less than or equal to 0.5 μm. The heater heats the medium to volatilize and strip the solvent in the ink. The ultraviolet light source irradiates dots of the glossy ink on the medium with ultraviolet light after a preset waiting time has passed subsequent to a timing of the droplets of the glossy ink landing on the medium.

There are disclosed methods for producing curable elastomeric compositions comprising carbon black particles, as well as their corresponding cured products. Such compositions, once cured, can be used for the preparation of numerous articles of wide industrial applicability.

A medium drying device that dries a liquid applied to a medium includes a front surface portion in contact with the medium at a first surface, a heat source unit provided on a second face side, a rear surface portion provided at a position opposing the second face with the heat source unit therebetween, a side surface portion disposed at a position opposing the heat source unit in a direction intersecting both the front surface portion and the rear surface portion, and a heat insulating material. The heat source unit opposes the second face without the heat insulating material therebetween, and the heat insulating material is disposed at a position opposing the rear surface portion and the heat source unit.

A dielectric heating apparatus includes: a conveyance unit configured to convey an object to be heated; an electrode unit including a first electrode and a second electrode which face the object to be heated, that is conveyed in a first direction, in a second direction intersecting the first direction and which are applied with an alternating current voltage; and a metal first cover unit configured to surround the electrode unit. The first cover unit includes a first insertion port through which the object to be heated is inserted into the first cover unit, a first feed-out port through which the object to be heated is fed out of the first cover unit, and a plurality of first opening portions that are different from the first insertion port and the first feed-out port.

A printing apparatus includes a heat transfer system for transferring heat away from or to a print medium moving in a movement direction through the printing apparatus. The heat transfer system includes a heat transfer member with a rotatable support surface configured for supporting the print medium. The heat transfer member is provided with at least one channel. The support surface is rotatable around an axis in order to move the print medium in the movement direction. A fluid circulation means is configured for supplying a fluid through said at least one channel. The at least one channel is configured such that, in operation, when fluid is supplied through said at least one channel, torque is generated in a fluido-mechanical manner around said axis, contributing to a rotational movement of the support surface of the heat transfer member.

An information processing device includes a storage portion storing a learned model trained by machine learning based on a data set in which temperature information, setting information, and countermeasure information are associated, a reception portion receiving the temperature information and the setting information at a time of ejecting ink by the printing head, and a processing portion deciding a countermeasure to be executed for condensation based on the received temperature information and setting information and the learned model.

Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.
