Down sequence when switching paper size
Purpose:
This down sequence prevents temperature rise of non-feeding area: there can be
possible fixing offset or wrinkle of the succeeding paper due to increased temperature
of non-feeding area of the preceding paper when continuously making prints or
feeding wider length of paper than the preceding paper.

4th Step
Starting conditions:
If the detected temperature of the sub thermistor reaches more than 210 deg C (*1)
when switching to the paper which has longer width than the preceding paper.
Operation:
Pickup of the succeeding paper and power distribution to the heater are stopped as
well to decrease the fixing temperature.
Completion conditions:
When the detected temperature of the sub thermistor reaches 170 deg C and less (*1)
*1. It is different according to setting value of the user mode (Special mode S or
Rotation/collation adjustment)
