This is an aluminum foil heater which heats the printed media from below in order to dry the ink. Internally, it is divided into post heater (1) [B] and post heater (2) [A], whose temperatures are controlled independently. Each heater has the thermistor [C] which detects the temperature. The post heater also has a thermostat [D] as a safety equipment. A thermistor [E] detects the temperature of the transport guide plate at the downstream side of the post heater and when the detected temperature reaches the value specified in SP1-108-002, turns OFF the heater. This prevents overheating of the area around the heater.

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.

It is kept at the temperature specified in SP mode when the RIP does not specify the temperature.
Automatic temperature control
When automatic temperature control (SP1-100-014) is ON, the temperature of the post heater (1) will be the average of the print heater (center) and the post heater (2). For example, when print heater (center) is 55 °C and post heater (2) is 70 °C, post heater (1) will be 63 °C.
Turning automatic temperature control (SP1-100-014) ON prevents rapid change of temperature on the path between the print heater and the post heater. This prevents deformation of the media.
