Ricoh Group Sustainability Report 201361
One of our goals is to reduce total lifecycle CO2฀emissions฀by฀30%฀by฀the฀year฀2020฀as฀compared฀
to the level of the year 2000. To reach this goal, the Ricoh Group is working to lessen the
environmental impact throughout the life cycles of our products, focusing specifically on the phase
that has the greatest impact — the daily usage of our products. Current Ricoh products require less
energy and help our customers to practice eco-efficiency in their work.

In฀June฀2013,฀Ricoh฀launched฀the฀RICOH฀MP฀C6003/
C5503/C4503/C3503/C3003฀series,฀a฀family฀of฀full-
color MFPs with a very short recovery time from energy-
saving (sleep) mode. Ricoh’s new Quick Start Up (QSU)
fusing system*2 and Color PxP-EQ, a low-temperature
fixing toner, were the keys to this achievement. Sleep
mode power consumption was also cut to less than 1W
through the use of an application-specific integrated
circuit (ASIC) that uses a low level of electricity.
