Image forming apparatus and non-transitory computer readable medium storing program

#This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2019-189166 filed Oct. 16, 2019.

#The present invention relates to an image forming apparatus and a non-transitory computer readable medium storing a program.

#There is known an image forming apparatus provided with a light emitter that supports handling of an image-formed paper or the like. By the light emitter being turned on, the user is notified of the discharge of the paper and the presence of the discharged paper. Alternatively, by the light emitter being turned on, the discharged paper and the surroundings are illuminated. For example, in a state where a paper sensor is embedded in a mounting surface such as a discharge tray and the paper sensor detects a paper, the light emitter is turned on.

#Exemplary embodiment(s) of the present invention will be described in detail based on the following figures, wherein:

#FIG. 1 is a perspective view illustrating a configuration example of an image forming apparatus according to an exemplary embodiment;

#FIG. 2 is a block diagram illustrating an image forming apparatus according to the exemplary embodiment;

#Hereinafter, exemplary embodiments will be described with reference to the drawings.

#An image forming apparatus according to an exemplary embodiment has a unit group and a processor. The unit group includes a specific unit, and the specific unit includes a specific component that performs an operation necessary for notifying of the paper remaining on the mounting surface. The processor controls supply of power to the unit group when returning from a sleep state based on a return event. Specifically, in a case where there is no paper on the mounting surface when transition to the sleep state (that is, in the case of “transition without paper”), in the return, the processor performs a first control to supply power to the specified power supply destination corresponding to the return event. Further, in a case where there is a paper on the mounting surface when transition to the sleep state (that is, in the case of “transition with paper”), in the return, even in a case where the specific unit is not included in the specified power supply destination, the processor perform a second control to supply power to the specific unit.

#The above configuration switches the power supply control or the power supply condition after the return, depending on the transition mode, that is, the transition without paper or the transition with paper. In the case of the transition without paper, normal power saving control for supplying power to the specified power supply destination corresponding to the return event after the return, that is, first control is executed. On the other hand, in the case of the transition with paper, special control for supplying power to at least the specific unit, that is, second control is executed. In the case of the transition with paper, power is supplied to the specific component after the return, so that the operation of the specific component can reliably notify of the paper remaining. The above control can reduce power consumption as compared to a case where power is uniformly supplied to the specific unit at the time of return regardless of the transition mode.
