● Down sequence when switching paper size
Purpose:
When feeding a sheet with a wider width than a preceding sheet during continuous printing,
temperature at the non paper-feed area of the preceding sheet increases, and it can cause
fixing offset and wrinkles when feeding the succeeding sheet. This down sequence controls
temperature increase at the non paper feed area.

Starting conditions:
The difference between the higher temperature detected by either Sub Thermistor (Rear)
(TH02) or Sub Thermistor (Front) (TH03) and the temperature of the Main Thermistor (TH01)
has become higher than the specified temperature (5 deg C).
Operation:
This is a control to stop pickup of the succeeding sheet and power distribution to the Fixing
Heater to reduce fixing temperature.
