International ClassB41J 002/01AbstractA color ink-jet printer having a heating blower system for evaporating ink carriers from the print medium after ink-jet printing. A preheat drive roller engages the medium and draws it to a print zone. The drive roller is heated and preheats the medium before it reaches the print zone. At the print zone, a print heater heats the underside of the medium via radiant and convective heat transfer through an opening pattern formed in a print zone heater screen. The amount of heat energy is variable, depending on the type of the print medium. A crossflow fan at the exit side of the print zone direct an airflow at the print zone in order to cause turbulence at the medium surface being printed and further accelerate evaporation of the ink carriers from the medium. An exhaust fan and duct system exhausts air and ink carrier vapor away from the print zone and out of the printer housing. | |
