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.
Starting conditions:
If the temperature difference between sub thermistor (front) and main thermistor or between sub thermistor (rear) and main thermistor exceeds 20 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 temperature difference between sub thermistor (front) and main thermistor or between sub thermistor (rear) and main thermistor reaches 20 deg C and less (*1) *1. It is different according to setting value of the user mode (Special mode S or Rotation/collation adjustment).
*1. It is different according to setting value of the service mode (Productivity priority mode or Productivity priority in rotation collation mode).
