1. A liquid discharge device comprising:
a conveyor including an unwinding roller to rotate in a direction in which a continuous form sheet being wound is unwound, and a winding roller to rotate in a direction in which the continuous form sheet unwound and fed from the unwinding roller is wound, and configured to convey the continuous form sheet from the unwinding roller to the winding roller;
a liquid discharger arranged between the unwinding roller and the winding roller in a conveying direction of the continuous form sheet, and configured to discharge liquid onto the continuous form sheet;
a dryer arranged between the liquid discharger and the winding roller in the conveying direction of the continuous form sheet, and configured to dry the liquid adhering to the continuous form sheet, setting a heater temperature higher as a conveying speed of the continuous form sheet by the conveyor becomes faster;
a seam detection sensor arranged between the unwinding roller and the liquid discharger in the conveying direction of the continuous form sheet, and configured to detect a seam of the continuous form sheet;
a temperature detection sensor configured to detect the heater temperature; and
a controller including a memory and a processor configured to control the conveyor based on detection results of the seam detection sensor and the temperature detection sensor,
wherein the controller determines, in a state of the liquid discharger discharging the liquid onto the continuous form sheet being conveyed by the conveyor at a first conveying speed, in response to a seam of the continuous form sheet being detected by the seam detection sensor, whether the heater temperature detected by the temperature detection sensor is higher than or equal to a threshold temperature,
wherein the controller causes, in response to the heater temperature being determined to be higher than or equal to the threshold temperature, the conveyor to stop conveying the continuous form sheet, until the heater temperature falls below the threshold temperature, and
wherein in response to determining that the heater temperature having fallen below the threshold temperature, the controller causes the conveyor to convey the continuous form sheet at a second conveying speed that is slower than the first conveying speed until the seam of the continuous form sheet is wound up around the winding roller.
