IMAGE FORMING APPARATUS AND METHOD OF CONTROLLING THE APPARATUS
First Claim
1. An image forming apparatus comprising:
- a job execution unit configured to execute a job that involves image formation;
a determination unit configured to, when a transition to hibernation is instructed, determine whether or not the job execution unit is executing an ongoing job;
an issuance unit configured to, if the determination unit determines that the job execution unit is executing the ongoing job, issue a job suspension request that makes the job execution unit suspend the ongoing job; and
a hibernation control unit configured to, in accordance with a response from the job execution unit in reply to the request of the issuance unit, generate a pre-processing sequence to be executed at the time of return from the hibernation, and execute hibernation processing,wherein the job execution unit prohibits a new job input in accordance with the job suspension request, and if the ongoing job involves data reception from an external apparatus, the job execution unit awaits for completion of the data reception and returns the response.

Abstract
The invention relates to an image forming apparatus having a hibernation function and a control method of the apparatus. When a transition to hibernation is instructed, it is determined whether or not a job is ongoing, and if it is determined that a job is ongoing, a job suspension request for suspending the ongoing job is issued. As a result, a job execution unit prohibits a new job input in response to the job suspension request, and if the ongoing job involves data reception from an external apparatus, the job execution unit awaits for completion of the data reception and returns the response. In accordance with the response, a pre-processing sequence to be executed at the time of return from the hibernation is generated, and hibernation processing is performed.

4. A method of controlling an image forming apparatus, comprising:
-
a job execution step of executing a job which involves image formation; a determination step of, when a transition to hibernation is instructed, determining by a determination unit whether or not the job execution step is ongoing; an issuance step of, if it is determined in the determination step that a job is ongoing, issuing a job suspension request which makes the ongoing job suspended; and a hibernation control step of, in accordance with a response to the job suspension request, generating a pre-processing sequence to be executed at the time of return from the hibernation, and executing hibernation processing, wherein in the job execution step, a new job input is prohibited in accordance with the job suspension request, and if the ongoing job involves data reception from an external apparatus, completion of the data reception is awaited and the response is returned. - View Dependent Claims (5, 6)
