Abstract

A server includes: a receiving unit receiving, from each of a plurality of image forming apparatuses, a schedule including information related to a period in which each image forming apparatus enters an energy saving mode; an analyzing unit analyzing the received schedules group by group; a changing unit changing the schedule or schedules of image forming apparatuses belonging to each group in accordance with the result of analysis; and a transmitting unit transmitting the changed schedule to a corresponding image forming apparatus. Each image forming apparatus operates in accordance with the schedule transmitted from the server. Thus, image forming apparatuses belonging to a group as a whole can be operated appropriately.

Claims

1. A server computer, comprising:

a receiving unit receiving, through a network, from each of a plurality of image forming apparatuses, a schedule including information related to a period in which each image forming apparatus enters an energy saving mode;

an analyzing unit analyzing said received schedule;

a changing unit changing said schedule in accordance with the result of analysis by said analyzing unit; and

a transmitting unit transmitting the changed schedule to the corresponding image forming apparatus.

2. The server computer according to claim 1, wherein

said analyzing unit calculates total sum of power use of prescribed image forming apparatuses not set to the energy saving mode among said plurality of image forming apparatuses and specifies an excess period in which the total sum exceeds a prescribed value in said schedule;

and

said changing unit sets at least one of said prescribed image forming apparatuses to the energy saving mode so as to have said total sum equal to or lower than said prescribed value in said excess period, and thereby changes the schedule of said image forming apparatus.

3. The server computer according to claim 1, wherein

said analyzing unit specifies, in the schedules of at least two of image forming apparatuses among said plurality of image forming apparatuses, an energy saving mode overlapping period in which periods set to the energy saving mode overlap;

and

said changing unit changes the schedules of said at least two image forming apparatuses such that of said at least two image forming apparatus, except for one of the image forming apparatuses, the remaining image forming apparatuses are not set to the energy saving mode in said energy saving mode overlapping period.

4. The server computer according to claim 1, wherein

said receiving unit receives information related to operating time of each image forming apparatus, from each of said plurality of image forming apparatuses;

said analyzing unit includes a calculating unit calculating relative usage rate from said information related to the operating time, for said plurality of image forming apparatuses; and

said changing unit changes the schedules of said plurality of image forming apparatuses such that the time period in which an image forming apparatus having smaller usage rate is set to the energy saving mode becomes longer.

5. An image forming system, comprising:

the server computer according to claim 1; and

a plurality of image forming apparatuses;

wherein

each of said image forming apparatuses transmits a schedule including information related to a period in which each image forming apparatus enters an energy saving mode to said server computer, receives the schedule changed by said server computer, and operates in accordance with said received schedule.
