next page) according to the detection result of main thermistor.
3. Sheet-to-sheet distance temperature control
To prevent the excessive temperature rise and to save the power consumption, the target temperature is set 5 deg C low (in
case of plain paper *1) from the printing temperature.
*1. When the fixing mode is the plain paper 1, plain paper 2 or thin paper, set to -5 dec C. In the other cases, set to -15 or
-20 deg C low or +5 deg C high according paper type
Target temperature during printing

The following 16 modes are provided as the fixing mode. The fixing modes are changed by the paper setting and the service
mode setting.
