Abstract
An image forming apparatus communicable with an external apparatus includes a reception unit configured to receive from the external apparatus a request for displaying a frame used to operate the image forming apparatus on a display of the external apparatus, an execution unit configured to perform shut down processing of the image forming apparatus when a predetermined time has elapsed, and a control unit configured to prevent the execution unit from performing the shut down processing in a case where the reception unit has received the request before the predetermined time has elapsed.
Claims7
An image forming apparatus comprising:
- a communicating portion configured to communicate with an external apparatus and being capable of executing a first process of transmitting information related to an input screen to the external apparatus so as to cause a web browser of the external apparatus to display the input screen prompting an input of information and a second process of receiving image information from the external apparatus;
- an image forming portion configured to form an image based on the image information;
- a power supplying portion capable of being in a plurality of states including a first state in which the power supplying portion supplies power to the image forming portion so as to enable the image forming portion to be able to form an image and supplies power to the communicating portion so as to enable the communicating portion to be able to perform communication, a second state in which the power supplying portion does not supply power to the image forming portion so as to cause the image forming portion to be unable to form an image and supplies power to the communicating portion so as to enable the communicating portion to be able to perform communication, and a third state in which the power supplying portion does not supply power to the image forming portion so as to cause the image forming portion to be unable to form an image and does not supply power to the communicating portion so as to cause the communicating portion to be unable to perform communication;
- a first executing unit configured to execute a third process of shifting a state of the power supplying portion from the second state to the first state, wherein the first executing unit does not execute the third process in a case where the communicating portion executes the first process when the power supplying portion is in the second state, and executes the third process in a case where the communicating portion executes the second process when the power supplying portion is in the second state;
- and
- a second executing unit configured to execute a fourth process of shifting a state of the power supplying portion from the second state to the third state in a case where the power supplying portion remains in the second state for a predetermined period of time, wherein the second executing unit does not execute the fourth process until a predetermined time passes since the execution of the first process.
A method for controlling an image forming apparatus comprising an image forming portion configured to form an image based on image information, a communicating portion configured to communicate with an external apparatus, and a power supplying portion capable of being in a plurality of states including a first state in which the power supplying portion supplies power to the image forming portion and supplies power to the communicating portion, a second state in which the power supplying portion does not supply power to the image forming portion and supplies power to the communicating portion, and a third state in which the power supplying portion does not supply power to the image forming portion and does not supply power to the communicating portion, the method comprising:
- executing a first process of transmitting information related to an input screen to the external apparatus with the communicating portion so as to cause a web browser of the external apparatus to display the input screen prompting an input of information;
- executing a second process of receiving image information from the external apparatus with the communicating portion;
- executing a third process of shifting a state of the power supplying portion from the second state to the first state in a case where the communicating portion executes the second process when the power supplying portion is in the second state, wherein the third process is not executed in a case where the communicating portion executes the first process when the power supplying portion is in the second state;
- and
- executing a fourth process of shifting a state of the power supplying portion from the second state to the third state in a case where the power supplying portion remains in the second state for a predetermined period of time, wherein the fourth process is not executed until a predetermined time passes since the execution of the first process.
