To automatically configure a weekly timer schedule depending on operation conditions ([Tracking Function Settings])

To display:
  • [Utility]
    • [Administrator Settings]
      • [System Settings]
        • [Weekly Timer Settings]
          • [Tracking Function Settings]

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.

You can select the [Auto Standby Adjustment Level] from the following five levels. The higher the level, the more likely it is that the machine will be judged to be inactive.

  • Level 1: The inactive rate is 71% or more.

  • Level 2: The inactive rate is 51% or more.

  • Level 3: The inactive rate is 41% or more.

  • Level 4: The inactive rate is 31% or more.

  • Level 5: The inactive rate is 10% or more.

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

  • To prevent the weekly timer setting from being changed drastically as a whole even in an irregular case where the operating hours are reversed between day time and night time, the time to be changed in a week is limited to one hour.

To confirm the weekly timer schedule configured by the tracking function ([Display ON/OFF Time])

To display:

      • [System Settings]
        • [Weekly Timer Settings]
