AR-M280U SIMULATIONS 9-2
*1: Only when this value is 0, control is performed with the actual
measurement value of process Thermistor.
If it is not 0, control is forcibly performed.
*2: When the drum motor standby time is greater than this value, the
correction of SIM 44-1 Vb1 is performed.
*3: This value is SIM 44-9 Vb1-1 correction value. The value
corresponding to the drum rotating time is used.
*4: This value is SIM 44-9 Vb1-2 correction value. The value
corresponding to the drum rotating time is used.
