Energy Save

• SP8-941-006: SC (excluding mode SC)
• SP8-941-007: Jam (plotter)
• SP8-941-009: Supply/PM unit end
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 customer’s 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 SP8-941-001 to 005.
• At the end of the measurement period, read the values of SP8-941-001 to 005 again.
• Find the amount of time spent in each mode (subtract the earlier measurement from the later
measurement).
• Multiply this by the power consumption spec for each mode.
• Convert the result to kWh (kilowatt hours)
Recommendation
We recommend that the default settings related to energy saving 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.
