*1: used to stabilization the rotation.
*2: moves the secondary transfer outside roller away from the ITB about 30 sec after the start of standby.
*3: executes temperature control (to 190 deg C) using the main heater or
the sub heater to suit the readings of the main thermistor (TH1) and the sub thermistor (TH2).
*4: causes the fixing roller to rotate idly according to the printing time.
(if 1 to 3 min, idle rotation for 30 sec; 3 min or more, idle rotation for 75 sec)
