Image forming device, image forming device controlling method, and recording medium

摘要

In an image forming device having a plurality of functions, a power measuring unit measures a power consumption of the image forming device, a power consumption computing unit computes a power consumption for execution of one of the plurality of functions based on the measured power consumption, a storage unit stores a target power consumption range for each of the plurality of functions, a measuring mode selecting unit selects one of a measuring mode and a non-measurement mode, and a power consumption estimation unit generates an estimated power consumption for execution of one of the plurality of functions in the non-measurement mode. The measuring mode selecting unit selects the measuring mode when the estimated power consumption in the non-measurement mode is beyond a target power consumption range for a corresponding function from the storage unit.

1. An image forming device having a plurality of functions, comprising:
a power measuring unit to measure a power consumption of the image forming device by measuring a total power entering the image forming device from a direct connection to an external power source, the power measuring unit including a power supply unit internal to the power measuring unit; a power consumption computing unit to compute a power consumption for execution of one of the plurality of functions with power supplied from a power supply unit external to the power measuring unit, based on the power consumption measured by the power measuring unit; a display unit to display the power consumption computed by the power consumption computing unit; a storage unit to store a target power consumption range for each of the plurality of functions; a measuring mode selecting unit to select one of a measuring mode in which electric power is supplied to the power measuring unit via the internal power supply unit and a non-measurement mode in which electric power is not supplied to the power measuring unit via the internal power supply unit; and a power consumption estimation unit to generate an estimated power consumption for execution of one of the plurality of functions in the non-measurement mode, wherein the measuring mode selecting unit selects the measuring mode when the estimated power consumption in the non-measurement mode generated by the power consumption estimation unit is beyond a target power consumption range for a corresponding one of the plurality of functions from the storage unit.
