Products that are not easy to use will not be chosen 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 energy-saving QSU (Quick Start-up) technology*,
which allows users to make copies whenever they need to. We are also expanding the product lineup of QSU-equipped machines with a view to reducing recovery time from energy-saving 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. Ricoh helps decrease the environmental impact caused
by customers' paper consumption by offering highly productive duplex copying functions, digitization, and by promoting sales of recycled paper.

In the field of high-speed multifunctional copiers, we launched the imagio MP 7501/6001 series equipped with our original energy-saving technology "HYBRID QSU" to realize a recovery time from energy-saving mode (sleep mode) of 10 seconds*1.
These models offer both user-friendliness and energy conservation by enabling warm-up to be completed quickly while users set documents and make copy settings,
even when the energy-saving mode is activated. These models also achieve the Typical Electricity Consumption
(TEC)*2 of 7.73 kWh*3. In addition, sales of copiers using QSU technology with a recovery time of less than 10 seconds from energy-saving mode are steadily increasing,
thus reducing CO2 emissions by approximately 48,200 tons a year (see graph(4)).

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.

- 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

- Energy 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.)
