Print system and image forming apparatus for setting a transition standby period

An image forming apparatus comprising:

• a notification part for providing, to a user, a notification of an inquiry about whether concurrent printing output that the image forming apparatus performs first printing output and subsequently performs second printing output is scheduled, in a non-sleep period associated with the first printing output by the image forming apparatus;
• and
• a setting part for setting a transition standby period for transition of the image forming apparatus to a sleep state at a first value when a reply for informing that the concurrent printing output is scheduled is not sent from the user, and setting the transition standby period at a second value which is larger than the first value when the reply is sent from the user;
• wherein in the non-sleep period associated with the first printing output by a first user, the notification part provides the notification to a second user;
• the image forming apparatus further comprising:
• a calculation part for calculating an estimated time of completion of the first printing output, wherein
• the notification part notifies the second user of the estimated time of completion calculated by the calculation part, and inquires of the second user as to whether the concurrent printing output is scheduled.

An image forming apparatus comprising:

• notification part for providing, to a user, a notification of an inquiry about whether concurrent printing output that the image forming apparatus performs first printing output and subsequently performs second printing output is scheduled, in a non-sleep period associated with the first printing output;
• and
• setting part for setting a transition standby period for transition of the image forming apparatus to a sleep state at a first value when a reply for informing that the concurrent printing output is scheduled is not sent from the user, and setting the transition standby period at a second value which is larger than the first value when the reply is sent from the user;
• wherein
• the setting part sets the second value so as to satisfy a condition that a power consumption amount in the transition standby period after extension associated with extension of the transition standby period is equal to or smaller than the power consumption amount at the time of return from the sleep state.
