Abstract

PURPOSE:To raise the temperature of a heater and to complete drying and fixing operation in a short time by reversing the wind direction of a duct when a form jam is detected and disconnecting the form from the heater. CONSTITUTION:The form 1 conveyed to the heater 4 by a conveyor roller 5 advances while pressed with air blown out of a duct 2 and moves in contact with the heater 4 by being sucked by air to a duct 3 to complete its fixation, so that the form is discharged. If the form 1 stays at the heater 4 owing to a form jam, etc., the power source of the heater 4 is disconnected, the wind directions of the ducts 2 and 3 are reversed to elevate the form 1, which is separated from the heater 4, so that the heater 4 is cooled by the air of the duct 3. Consequently, the temperature of the heater 4 during drying and fixing operation is raised to complete the drying and fixing operation in a short time.

り、解決を計ったものである。In order to complete drying and fixing in a short time, a method is used in which the paper is moved in contact with a heating element in order to improve heat conduction to the paper, but in order to increase the printing speed, the temperature of the heating element is set high. It is necessary to consider safety issues such as preventing the paper from burning if a paper jam occurs or the paper stops on the heating element. For this purpose, it is necessary to separate the paper from the heating element when a paper jam occurs or the paper is stopped, but the present invention attempts to solve this problem by using a method of blowing air from the heating element side.

It advances while being held down by the wind blown out by A2, and is pulled by the suction wind from duct B5, moves while contacting the heater 4, completes fixing by the heat of the heater 4, and is ejected by the ejection roller 6. . Fig. fa2 shows a case where the paper 1 is stuck at the heater 4 due to a paper jam or the like. When a paper jam is detected, the power to heater 4 is cut off, and duct A
2. Since the direction of the wind in the duct B3 is reversed, the paper 1 is lifted and separated from the heater 4. The heater 4 is
