From when the power switch is turned on to when the surface tem-

From when the surface temperature of the fixing assembly has
reached 195°C to when it reaches 200°C; this is to even out the
surface temperature of the fixing roller.
From when INTR ends to when the drum surface potential for
copying has been measured; this is to measure the drum surface
potential (VD, VL1, VL2) and to control it.
From when CNTR1 ends to when the drum surface potential for
printing has been measured; this is to measure the drum surface po-
