An image forming apparatus includes a plurality of devices configured to perform different job processing, a control unit configured to control job processing performed by each device, a reception unit configured to receive an instruction for causing the control unit to shift to a state where the job processing is capable of being performed, and a power control unit configured to, when the control unit is shifted to a stand-by state in response to receiving the instruction, supply a power to a device specified based on a job processing function corresponding to an initial screen to be displayed.

An information processing apparatus includes a storage unit configured to store information related to an activation of the information processing apparatus, a control unit configured to perform a control such that, in a case where the information stored in the storage unit relates to a first activation, the information processing apparatus is shifted into a standby state when power is supplied to the information processing apparatus, and in a case where the stored information relates to a second activation, the information processing apparatus is shifted into the standby state when the power is supplied to the information processing apparatus and also a signal input to the control unit is put into a particular state, and a power supply control unit configured to put the signal input to the control unit into the particular state when the information processing apparatus is not shifted into the standby state even when the power is supplied.

An information processing apparatus includes a plurality of human body detecting sensors that detect a user, each of the human body detecting sensors having a detection area for detecting the presence of the user; an operation part that receives an operation by the user; and an erroneous detection determination part that determines an erroneous detection if the operation part does not receive the operation by the user within a predetermined time after one of the human body detecting sensors detects the presence of the user. If a number of erroneous detections of the one of the human body detecting sensors is equal to or more than a first threshold, the erroneous detection determination part sends an instruction to reduce the detection area to the one of the human body detecting sensors and sends an instruction to increase the detection area to another one of the human body detecting sensors.

An information processing apparatus that reduces power consumption using IEEE802.11ah connection without spoiling usability of wireless communication. The information processing apparatus includes a memory device that stores instructions, and a processor that executes the instructions to wirelessly communicate with an external apparatus by at least one of a first communication function that wireless communicates by a first wireless communication method that conforms to IEEE802.11ah and a second communication function that wirelessly communicates by a second wireless communication method of which a communication speed is higher than that of the first wireless communication method, determine whether an electric power state of the apparatus is a second electric power state in which power consumption is lower than a first electric power state, and prompt a user to set switching setting that stops the second communication function and starts the first communication function in the second electric power state.

An image forming apparatus includes: an operation panel having an operation surface for accepting operations from a user; a photovoltaic module for generating electric power upon reception of light; and a support member for supporting the photovoltaic module in such a way that the photovoltaic module is placed above the operation surface of the operation panel. The photovoltaic module is supported so as to be pivotable relative to the support member.

Information is stored indicating a power state to which a printing apparatus is to be shifted. When a power switch receives a power off instruction, the printing apparatus is shifted to a first power state or a second power state in accordance with the stored information. In a first power state, power is supplied to a part of devices provided in the printing apparatus, and in a second power state, power is not supplied to the part of devices in the printing apparatus.

An image forming apparatus includes a main CPU, and, in an unused period in which the image forming apparatus is not used, the main CPU detects whether or not a person exists within a human detection range, on the basis of an output of a human detection sensor. When a person has been detected, by outputting a notification voice regarding an intruder, which indicates that the intruder has been detected, from a speaker, the main CPU notifies the surroundings of the image forming apparatus and also transmits an electronic mail including a message indicating that the intruder has been detected to an address that has been registered in advance and thereby notifies a user of a terminal of the address of the detection of the intruder.

An MFP communicates with a DNS server through a network. This MFP includes an operation unit that sets whether a printing service is activated or not and a controller unit that registers search information in which capability information provided for a client terminal and information relating to name resolution are associated with each other in the DNS server in accordance with activation of the printing service being set by this operation unit.

A communication apparatus includes a connection unit, a storage unit, first and second processing units, and a control unit. The storage unit operates in one of a first state where a memory keeping process to keep information stored in the storage unit is executed in response to accepting an outside instruction, and a second state in which the memory keeping process is executed without accepting an outside instruction. The first processing unit performs a first process based on network received information and the stored information. The second processing unit performs a second process different from the first process and based on the stored information. The control unit forces the storage unit to transit from the first to the second state where the first and second processing units are not accessing the storage unit. Consumption power consumed in the first state is larger than consumption power consumed in the second state.

An image forming apparatus includes a capacitive human body sensor that detects an operation to return to a normal mode from a power saving mode consuming less power than the normal mode, wherein an antenna of the human body sensor is wired along a periphery of a predetermined detection target area which can receive the operation to return from a user, and a difference in sensitivity between a corner portion and a part other than the corner portion of the antenna is reduced by shaping the antenna at least to be wired in a curve without forming a corner in the corner portion, to be thinner in the corner portion than in the part other than the corner portion, or to be wired without meandering in the corner portion and wired while meandering in the part other than the corner portion.
