The print heater is an aluminum foil heater which heats the media uniformly during printing in order to control the spreading of ink drop (dot gain). Internally, it is divided into the print heater end left [A], the print heater center [B], and the print heater end right [C] to prevent temperature unevenness which can be caused by the temperatures at the edges of the heater being lower. Each heater has the thermistor [D] which detects the temperature. The print heater also has a thermostat [E] as a safety equipment.
Target Temperature
The target temperature of each heater is controlled by the RIP or SP. The machine compares the temperature detected by the thermistor and the target temperature, and controls the temperature by turning the heater ON/OFF. The temperature of the print heater is controlled according to the media size as follows.
