ABSTRACT:
An image processing system integral with an image output unit having a power saving mode comprises a temperature detection section for monitoring a fuser temperature in a power saving mode or a rotation detector for a polygonal motor, a control section for outputting a control signal at a predetermined timing, and an energization control section capable of turning on/off output in response to the control signal from the control section. The timing of a power saving mode off signal output by the control section is when the fuser temperature lowers to a temperature or the polygonal motor take longer to ramp up than the time until the image output unit, after the power saving mode is released, is placed in a reprintable state becomes longer than the time required for setting up the data required when image processing is performed. Thus, the transition time to the copyable state as a whole is used efficiently, and power consumption can be reduced. The user saves power effectively by the operation in the power saving mode. When the power saving mode is released, setting up an image processing section does not cause the user to wait for copy start.
