Abstract
A hot-melt type ink jet printer includes a nozzle head for ejecting a hot-melt type ink onto a sheet. The printer has a sheet feed passage defined by, in order from an upstream side in a sheet feeding direction, a sheet supply roller, a preheat platen, a sheet feed roller, a main platen, a cooling platen, discharge roller and a sheet discharge opening. The preheat platen and main platen have preheater and main heater, respectively, and these platen and the cooling platen are supported on a frame. A first suction port is formed between the main platen and the cooling platen and a second suction port is formed between the cooling platen and the frame. A power board and a cooling fan is provided within the frame for cooling the power board. By rotation of the cooling fan, air is introduced from the sheet discharge opening into the frame through the first and second suction ports to also cool the cooling platen and the heating platen.
