Provided is a transport device including a feeding unit on which a roll-type medium is set and which feeds the medium by rotating the medium, and an endless transport belt that transports the medium in a transport direction by supporting the medium fed out from the feeding unit and rotating. When seen from a support direction in which the transport belt supports the medium, the feeding unit is configured to change the posture thereof so as to incline a rotating shaft of the medium with respect to a width direction that is a direction intersecting the transport direction.

Transport device, printing apparatus, and method for adjusting feeding unit

A printing apparatus includes a printing unit that performs printing on a printing medium, a transporting belt that transports the printing medium and has an endless shape, and a belt-driving roller that causes the transporting belt to circulate and has a cylindrical shape. In the transporting belt, a magnetic scale having a magnetic pole changing at a predetermined pitch is arranged along a transport direction of the printing medium. The belt-driving roller includes an outer circumferential surface constituted of a magnet body, and is in contact with the transporting belt at the outer circumferential surface. The circumferential length of the outer circumferential surface of the belt-driving roller is an integer multiple of the pitch of the magnetic scale.

Printing apparatus and method of controlling printing apparatus

There is provided a medium conveying device which includes a conveyance belt passed around a first roller and a second roller and configured to support and convey a medium on a supporting surface, and in which a controlling unit is able to execute first control to determine whether a first skewing direction and a second skewing direction are the same, the first skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the first rotational direction, the conveyance belt moves toward one side or the other side in a width direction intersecting a moving direction of the conveyance belt, and the second skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the second rotational direction, the conveyance belt moves toward the one side or the other side in the width direction.

Medium conveying device, recording device, and method for determining skewing state of conveyance belt

Provided is a printing apparatus that includes a printing unit, a conveyance belt that is stretched over a first roller and a second roller such that a tension is applied to the conveyance belt, and a control unit configured to perform on the conveyance belt a forward rotation operation configured to convey a medium in a conveyance direction and a reverse rotation operation configured to convey the medium in a reverse conveyance direction. When the reverse rotation operation has been performed during a print pause period and the tension at the end of the print pause period has changed from the tension when printing of a first image is complete due to the reverse rotation operation performed during the print pause period, the control unit corrects a rotation amount of the conveyance belt in a first rotation direction during printing of a second image.

Printing apparatus and medium conveyance method

A printing apparatus includes a recording section including a plurality of ink heads configured to discharge, ink, a first reaction solution head, and a second reaction solution head configured to discharge the reaction solution, a driving section configured to drive the recording section, and a controller configured to execute causing the driving section to move the recording section in a first direction, causing the plurality of ink heads to discharge the ink, and causing the first reaction solution head and the second reaction solution head to discharge the reaction solution. The plurality of ink heads are arranged in the first direction. The first reaction solution head is located downstream in the first direction of an ink head located most downstream in the first direction. The second reaction solution head is located between two ink heads located adjacent to each other in the first direction.

Printing apparatus

An image forming apparatus includes a reaction liquid application portion that applies reaction liquid to a recording medium, an ink application portion that applies ink which includes a color material that is coagulated using the reaction liquid onto the recording medium onto which the reaction liquid is applied, and a control portion that adjusts an amount per unit area of the reaction liquid that is applied to the recording medium from the reaction liquid application portion according to infiltration into the recording medium.

Image forming apparatus and image forming method

A printing apparatus includes a reaction liquid application portion that applies dots of reaction liquid onto a recording medium by applying the reaction liquid to pixels in a pixel array in which rasters in which a plurality of pixels are lined up in a first direction are lined up in a second direction which is orthogonal to the first direction and an ink application portion that applies ink dots to the recording medium by applying ink which includes a color material that is coagulated using an action of the reaction liquid to the pixels of the pixel array, in which the reaction liquid application portion applies the reaction liquid dots by being separated by one pixel or more in the first direction and the second direction.

Printing apparatus and printing method

A liquid ejecting apparatus which includes a carriage including an ejecting unit which ejects liquid onto a medium, and can move in a reciprocating direction, in which the carriage includes catching units which catch mist which occurs along with ejecting of the liquid from the ejecting unit on at least one side of the ejecting unit in the reciprocating direction, and the catching units include a fan which moves the mist from the catching units by generating an air current.

Liquid ejecting apparatus

A liquid ejecting apparatus which includes an ejecting unit which ejects liquid, and a collecting unit which collects mist which occurs along with ejecting of the liquid from the ejecting unit from a collecting port, in which the collecting unit includes a backflow prevention unit in the collecting port. By adopting such a liquid ejecting apparatus, it is possible to suppress backflow of mist of the liquid from the collecting unit which collects mist of the liquid which occurs along with ejecting of liquid from the ejecting unit.

A liquid ejecting apparatus which includes a carriage which can move in a reciprocating direction, in which the carriage is provided with an ejecting unit which ejects liquid, a circuit board which inputs a signal to the ejecting unit, and a fan which can blow air toward the circuit board, and includes a separator which separates a path through which mist which occurs along with ejecting of liquid from the ejecting unit reaches the fan.

A liquid discharging apparatus includes multiple nozzle rows, in which a plurality of nozzles capable of discharging liquid onto a medium are arranged, that are arranged in an intersection direction intersecting with a nozzles-arranged direction where the nozzles are arranged, a shielding portion that shields an area between the nozzle rows, and a collecting portion that collects mist which is attached to the shielding portion and is generated due to discharging of the liquid from the nozzles.

Liquid discharging apparatus

An image forming apparatus of the invention includes; a cleaning member that collects liquid developer by cleaning a developer carrier; a first transporting path that moves the liquid developer collected by the cleaning member; an oscillating member that applies vibration to the liquid developer transported from the first transporting path; a developer supply unit that stores the liquid developer transported from a first transporting mechanism; a second transporting mechanism that includes a second transporting path that transports the liquid developer stored in the developer supply unit to a developer storage in a developing unit; and a control unit that adjusts a toner charge current applied to the toner charging unit and controls vibration applied to the oscillating member on the basis of the adjusted toner charge current.
