Temperature Control

• The fusing temperature is increased to a predetermined level during the warm-up cycle.
• The warm-up control is provided when power is turned ON, the Front Door is opened and
closed, and the Energy Save mode is canceled.
• In the standby state, the fusing temperature is set to a level (130 °C) lower than that dur-
ing a print cycle, thereby cutting down power consumption.
• The temperature control mode when the control is resumed (when power is turned ON,
the Front Door is opened and closed, or the Energy Save mode is canceled) is set
according to the mode and the fusing temperature valid before the interruption.
• In the Energy Save mode, the Fusing Roller Heater Lamp is turned OFF to reduce power
consumption.
