Abstract: A recording method which uses a water-based ink composition and a treatment liquid containing an aggregating agent, includes: a main scanning to eject the ink composition and the treatment liquid from an ink jet head so as to be adhered to a recording medium while the ink jet head is transferred with respect to the recording medium; a sub-scanning to transport the recording medium in a sub-scanning direction which intersects a direction of the main scanning; and a ventilation step of sending a wind to the recording medium in the main scanning. In the main scanning, by a portion of the ink jet ink head to eject the ink composition and the treatment liquid located upstream in the sub-scanning direction, the ink composition and the treatment liquid are overlapped and adhered to the same main scanning region of the recording medium by the same main scanning, and by a portion of the ink jet ink head to eject the ink composition and the treatment liquid located downstream in the sub-scanning direction, the ink composition is adhered to the recording medium, and when the ink composition is adhered thereto, the treatment liquid is not overlapped and adhered to the same main scanning region of the recording medium by the same main scanning. In addition, when the main scanning is performed, the recording medium to which the ink composition and the treatment liquid are adhered has a surface temperature of 33° C. or less.

Abstract: Disclosed is a system and method for cooling paper within a printer assembly that includes at least one misting assembly designed to mist an aqueous solution onto an unprinted surface of paper stock after a first side is printed. At least one convection accelerator assembly is designed to accelerate evaporation of the aqueous solution before the printed paper stock arrives at the at least one printing station for printing on the unprinted surface. At least one or more of a paper temperature, machine temperature, printhead temperature, and humidity sensor are operationally coupled to at least one controller assembly programmed to control at least one or more of misting, humidity, and airflow. The at least one controller assembly is designed to determine the heat to be dissipated into the airflow from the printed paper stock to obtain a targeted paper temperature and, therefore, the amount and placement of aqueous solution misted.

Abstract: An image forming apparatus includes: an image forming portion which discharges ink onto a recording medium to form an image; a heat source portion which heats the ink on the recording medium; an exhaust air duct from which gas heated by the heat source portion is exhausted; and a detection portion which detects smoke or gas generated at a time of fire. The exhaust air duct is arranged such that an inlet from which gas is sucked in opposes the heat source portion. The detection portion is arranged inside the exhaust air duct.

Abstract: An inkjet recording apparatus includes a conveying portion, a recording portion including a line head including a plurality of recording heads, a temperature detecting portion, a cooling mechanism, and a control portion. The cooling mechanism includes a storing portion that stores cooling liquid, a circulation path of the cooling liquid that is arranged to be branched into a plurality of branch paths passing near the recording heads, a heat dissipating portion that dissipates heat of the cooling liquid, and a pump that causes the cooling liquid to circulate. If there exists, among the recording heads, a recording head that is predicted to undergo a temperature rise, the control portion increases a flow amount or circulation time of the cooling liquid in whichever of the branch paths serves as a flow path of the cooling liquid flowing toward the recording head that is predicted to undergo a temperature rise.
