Energy Conservation / Prevention of Global Warming -Concept, Targets and Results-

Products that are not easy to use will not be selected by customers, even if their energy-saving performance is solid. Such products can neither contribute to energy conservation nor help prevent global warming.
Ricoh is further developing its unique and easy-to-use energy-saving QSU (Quick Start-Up) technology^*, which enables users to make copies as soon as they need to. We are also expanding the product lineup of QSUequipped machines with a view to reducing recovery time from energysaving mode to less than 10 seconds for all our models in the future. Meanwhile, reducing unnecessary paper consumption (indirect energy saving) is important since paper production consumes a lot of energy. Therefore Ricoh is helping to decrease the environmental impact caused by customers' paper consumption by offering highly productive duplex copying functions, digitization, and by promoting sales of recycled paper.

• *Ricoh's original energy-saving technology that enables quick recovery from energy-saving standby mode.

Achieve Ricoh's energy-saving goals.

We released the imagio MP C3301/2801 series and the imagio MP C2201 series multifunctional color copiers during the fiscal year. These models feature Ricoh's original energy-saving QSU technology and are able to recover from energy-saving (sleep) mode within less than 10 seconds, the first in the multifunctional color copier segment to achieve this. In addition, the imagio MP C2201 series achieved Typical Electricity Consumption (TEC)^*1 of 1.07 kWh^*2 by reducing the aforementioned recovery time, requiring less electricity consumption, and achieving quicker switch to energysaving mode after operation. Sales ofcopiers using QSU technology with a recovery time of less than 10 seconds from energy-saving mode have been steadily increasing, thus reducing CO₂ emissions by approximately 42,600 tons during the year (see graph (4)).

• *1The measuring procedure is defined by the international ENERGY STAR Program.
• *2Indicates the value for imagio MP C2201 SP. The value for imagio MP C2201 SPF is 1.31 kWh.

We will further improve QSU technology, so that more customers will use energy-saving mode, and pursue user-friendliness (shorter recovery time from energy-saving mode) and energy-saving for color copiers.

Changes in energy consumption

Energy conservation values are calculated as follows:
∑(<Energy consumption when recovery time is 10 seconds (kWh) ^*1> × Annual number of units marketed)/∑Annual number of units marketed

• *1Energy consumption when recovery time is 10 seconds: Based on TEC measured for models with a 10-second recovery time from energy-saving mode in accordance with the method defined by the International ENERGY STAR Program.
  (Electricity consumption in standby mode was measured for models with a recovery time of more than 10 seconds.)

• *Graphs (1) and (2) were compiled based on the number of units marketed in Japan.

Changes in recovery time from energy-saving mode

Energy conservation values are calculated as follows:
∑(<Recovery time from sleep mode (sec.)> × Annual number of units marketed)/∑Annual number of units marketed
