Managing the Power Supply for Power Saving (For Administrators)

Change the time required to automatically change to the Sleep mode after you did not operate this machine.

Sleep mode provides a greater power saving effect than the Low Power mode. However, the time required to return to the normal mode is longer than the time required to recover from the Low Power mode.

bizhub C658/C558/C458: [15] min. is specified by default (allowable range: [2] to [60] min.).

bizhub C368/C308/C258: [20] min. is specified by default (allowable range: [2] to [60] min.).

Change the time required to automatically change to the Low Power mode after you did not operate this machine.

In the Low Power mode, the display of the Touch Panel is turned off to reduce power consumption.

[15] min. is specified by default (allowable range: [2] to [60] min.).

Select whether to use the Power key on the Control Panel as a sub power OFF key or as a power save key. [Power Save] is specified by default.

When using this machine in the factory default status, choose this setting to select the type of the power save mode when pressing the Power key on the Control Panel. [Low Power] is specified by default.

When this machine receives a print job from a fax machine or computer in the Power Save mode, select the timing to switch to the Power Save mode after the print job has ended. [Immediately] is specified by default.

Select whether to reduce the power consumption in the Sleep mode. [High] is specified by default.

Select whether to give priority to the power saving when returning from the Sleep or sub power off mode to a mode other than the copy mode. [Standard] is specified by default.

When returning to a mode that does not involve printing, such as scan/fax mode, power consumption can be reduced by not adjusting the temperature of the Fusing Unit on this machine.

You can set this option when you have selected an option other than [Copy] in [Priority Mode] that is selected by [Administrator Settings] - [System Settings] - [Reset Settings] - [System Auto Reset].

Specify whether to use the weekly timer. Then, select a power save mode for the machine to enter according to the weekly timer.

Configure the day to which the weekly timer is applied.

Select the day to which the weekly timer is applied by switching the calendar by [Year] and [Monthly]. Optionally, you can collectively configure the appropriate days for each day of the week with [Daily Setting].

Specify whether to set a time zone for switching the machine in the normal mode with the weekly timer enabled temporarily to the sleep mode during lunch time, for example.

[OFF] is specified by default.

Specify whether to restrict the use of this machine in the Power Save mode by requesting a password.

To request a password in order to restrict operation, enter the password for a user to enter (using up to eight characters).

[No] is specified by default.

Specify whether to use the tracking function that automatically adjusts the weekly timer On or Off time to fit the user's operating conditions or office use status.

When the tracking function is used, the inactive rate is calculated for each time zone based on the machine use status over the past four weeks. Based on the inactive rate thus calculated, the (inactive) time zone in which the machine is not operating is determined, and the result is reflected to the weekly timer On or Off time.

You can adjust the judgment criteria for non-operation, which defines the minimum inactive rate requirement of the machine in [Auto Standby Adjustment Level].

Inactive rate

The inactive rate is calculated for each time zone based on the machine use status over the past one to four weeks. To come closer to the actual operating status of the user, the inactive rate of one week ago is weighed at 40%, two weeks ago at 30%, three weeks ago at 20%, and four weeks ago at 10%.

[Auto Standby Adjustment Level]

Select the judgment criteria for non-operation, which is defined to be less than the minimum active rate requirement of the machine based on the calculated inactive rate. If the inactive rate exceeds the selected value in a certain time zone, it is judged that the machine is inactive for the time zone.

[ON] is specified by default. The default of [Auto Standby Adjustment Level] is [Level 3].

Displays the switching times to enter the power save mode ([OFF Time]) and to the normal mode ([ON Time]) set by the tracking function.

Tap the [Clear Usage Data] to delete data related to the usage status of this machine and reset the values for [OFF Time] and [ON Time] that have been automatically set.
