Abstract
An image forming apparatus includes a CPU and a camera. In the image forming apparatus, the camera takes a facial image of a user approaching the image forming apparatus, and on the basis of the facial image, face authentication is executed. Further, in a case where it has been determined as a result of the face authentication that the user approaching the image forming apparatus is a registered user, it is determined whether there is registered job data registered by the registered user. The image forming apparatus is switched from a power-saving mode to a normal mode in a case where it has been determined that there is registered job data of the user approaching the image forming apparatus.
Claims8
An image forming apparatus including a hard disk drive (HDD) that is able to store therein a facial image of a registered user and predetermined registered job data registered by the registered user and having a power-saving state in which an amount of power consumption is limited to a predetermined value or smaller-and a normal state in which the amount of power consumption is not limited, comprising:
- a human detection sensor that detects whether a user is present in a first range within an area around the image forming apparatus;
- a first determination processor that, in a case where the human detection sensor detected that a user is present in the first range, determines whether the user is the registered user;
- a second determination processor that, in a case where the first determination processor has determined that the user is the registered user, determines whether the HDD has stored therein the predetermined registered job data registered by the registered user, and in a case where the HDD has not stored therein the predetermined registered job data, does not search the predetermined registered job data;
- and
- a state setting processor that sets the normal state in a case where the second determination processor has determined in the power-saving state that the HDD has stored therein the predetermined registered job data registered by the registered user, and maintains the power-saving state in a case where the second determination processor has determined in the power-saving state that the HDD has not stored therein the predetermined registered job data-registered by the registered user.
A non-transitory storage medium having stored thereon a control program for an image forming apparatus including a hard disk drive (HDD) section that is able to store therein a facial image of a registered user and predetermined registered job data registered by the registered user and having a power-saving state in which an amount of power consumption is limited to a predetermined value or smaller and a normal state in which the amount of power consumption is not limited,
- the control program causing a processor of the image forming apparatus to execute a process comprising:
- (a) determining whether a user is present in a first range within an area around the image forming apparatus;
- (b) in a case where, in (a), it has been determined that a user is present in the first range, determining whether the user is the registered user;
- (c) in a case where, in (b), it has been determined that the user is the registered user, determining whether the HDD has stored therein the predetermined registered job data registered by the registered user, and in a case where the HDD has not stored therein the predetermined registered job data, does not search the predetermined registered job data;
- and
- (d) setting the normal state in a case where, in (c), it has been determined in the power-saving state that the HDD has stored therein the predetermined registered job data registered by the registered user, and maintaining the power-saving state in a case where, in (c), where it has been determined in the power-saving state that the HDD has not stored therein the predetermined registered job data registered by the registered user.
A control method by which a processor of an image forming apparatus including a hard disk drive (HDD) that is able to store therein a facial image of a registered user and predetermined registered job data registered by the registered user and having a power-saving state in which an amount of power consumption is limited to a predetermined value or smaller and a normal state in which the amount of power consumption is not limited executes a process comprising:
- (a) determining whether a user is present in a first range within an area around the image forming apparatus;
- (b) in a case where, in a case where, in (a), it has been determined that a user is present in the first range, determining whether the user is the registered user;
- (c) in a case where, in (b), it has been determined that the user is the registered user, determining whether the HDD has stored therein the predetermined registered job data registered by the registered user, and in a case where the HDD has not stored therein the registered predetermined job data, does not search the registered predetermined job data;
- and
- (d) setting the normal state in a case where, in (c), it has been determined in the power-saving state that the HDD has stored therein the predetermined registered job data registered by the registered user, and maintaining the power-saving state in a case where, in (c), it has been determined in the power-saving state that the HDD has not stored therein the predetermined registered job data registered by the registered user.
