Print temperature control
Startup (warm-up rotation) temperature control
To increase fixing temperature to be ready for printing after receiving the print-start command
Print temperature control
To set optimal target temperature to prevent fixing failure or offset, and keep the specified target temperature during printing
A.Setting target temperature
Target temperature is specified depending on the paper type, paper size, elapsed time since the last control (including the standby control) of fixing temperature and fixing temperature at the start of warm-up control.
B.Temperature control during printing
When the paper passes in the fixing unit, the fixing temperature is controlled to keep the target value (see the table on the next page) according to the detection result of main thermistor.
C.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. Set to 5, 15 or 20 deg C low according paper type
Target temperature during printing
The control temperature is determined according to the fixing mode or to the fixing temperature at the start of warm-up control. The 12 modes are provided as the fixing mode for the selected feed table and paper type.
The following table is the control temperature when the fixing temperature is less than 55 deg C at the start of warm-up control.
