• 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.

■ Down sequence control
● Down sequence when feeding small size paper
Purpose:
• To prevent temperature rise of non-feeding area in the case of continuous print of small size paper (less than A4 of length
in width direction), fixing offset or deterioration of fixing film.
Starting conditions:
• The down sequence is performed step by step. When the detected temperature of sub thermistor reaches the following
temperature or higher for 430 msec continuously, the productivity decreases every one step.
