The recovery time depends on the model and the region.
• 5.1 sec. or less
Off/Sleep Mode
Recovery time.
• 5.6 sec. or less
Recommendation
We recommend that the default settings should be kept.
• If the customer requests that these settings should be changed, please explain that their energy
costs could increase, and that they should consider the effects on the environment of extra energy
use.
• If it is necessary to change the settings, please try to make sure that the Auto Off timer is not too
long. Try with a shorter setting first, such as 30 min., then go to a longer one (such as 60 min.) if the
customer is not satisfied.
• If the timers are all set to the maximum value, the machine will not begin saving energy until 240
minutes has expired after the last job. This means that after the customer has finished using the
machine for the day, energy will be consumed that could otherwise be saved.
• If you change the settings, the energy consumed can be measured using SP8941, as explained
below.
Energy Save Effectiveness
SP 8941 (Machine Status) keeps a record of the amount of time that the machine spends in each mode.
• 8941-001: Operating mode
• 8941-002: Standby mode
• 8941-004: Low power mode
• 8941-005: Off/sleep mode
With this data, and the power consumption values from the specifications, we can estimate the amount
of energy that is used by the machine.
This should only be used as a reference value, because the power consumption specifications are
measured in a controlled environment with a constant power supply.
To get an exact measurement at the customers site, a watt meter must be used to measure the actual
energy consumed.
To use SP8941 to calculate the energy consumed:
• At the start of the measurement period, read the values of SP8941 001 to 005.
• At the end of the measurement period, read the values of SP8941 001 to 005 again.
