*1: H3 and H4 turn ON in alternate shifts (50 % Duty)
*2: 1/3-speed rotation
*3: Sheet-to-sheet attachment/detachment of the fixing belt
*4: Fixing web solenoid is turned ON once for each small paper, and twice for each paper larger than that.
*5: Only when the temperature of the inlet roller main thermistor (THM3) is detected as 100 deg C or more.
The fixing belt is attached/detached during the sheet-to-sheet interval.
Cause:
When paper is not passing (=sheet-to-sheet interval), the fixing belt is detached to prevent temperature rise.
