According to one embodiment, an ink jet recording apparatus includes a first ink jet head, a second ink jet head, a main feeding passage, a first roundabout feeding passage, and a controller. The first ink jet head forms an image on a medium. The second ink jet head forms an image on the medium. The main feeding passage feeds the medium so that the first ink jet head and the second ink jet head form an image on the medium. The first roundabout feeding passage feeds the medium without allowing the medium to face the first ink jet head. The controller controls so as to feed the medium through the first roundabout feeding passage if the first ink jet head is unusable.

An image recording apparatus includes a conveyance unit which includes a conveyance belt and an air suction unit for sucking air through the conveyance belt to adsorb a recording medium onto the conveyance belt. A recording head ejects ink to carry out recording on the recording medium conveyed by the conveyance unit. An adsorption force adjusting unit adjusts the adsorption force for the recording medium on the conveyance belt, which occurs by sucking air, according to the size of the recording medium.

An ink jet recording apparatus includes an ink jet head in which a plurality of nozzles are arranged, a sub-scan driving unit which carries a recording medium to be formed with an image, a first carrying unit which is disposed on a downstream side of a carrying direction of the recording medium by the sub-scan driving unit and carries the recording medium on which an image is formed by the ink jet head, and a second carrying unit which is disposed so as to face the first carrying unit and heats the recording medium interposed between the first carrying unit and the second carrying unit.
摘要:
An inkjet recording device has a conveying path, a feed mechanism configured to feed the paper sheet on the conveying path in the feed direction, an inkjet head configured to make droplets land on the paper sheet, a suction mechanism configured to suction the paper sheet towards the conveying path, and the control mechanism configured to predict the extent of the cockling caused in the paper sheet on which the droplets land based on either one of paper sheet information of the paper sheet and information of the image to be formed on the paper sheet to control suction force of the suction mechanism in accordance with the degree of the cockling.
摘要:
According to one embodiment, an inkjet image forming apparatus includes a transport section configured to adsorb a recording medium by suction to transport the recording medium under inkjet heads, and a controller configured to perform control in a manner that an adsorption force to the recording medium if the image is formed on a second surface of the recording medium is larger than an adsorption force to the recording medium if the image is formed on a first surface of the recording medium.
