The "RICOH MP 6054/5054/4054/3554/2554" black-and-white digital multifunction printers released in October 2014 are equipped with Ricoh's unique energy-saving technologies: the quick start-up (QSU) technology (DH fixing system)*1 and a low-melting-point toner. Thanks to these systems, the printers provide the industry's top-tier energy efficiency, with their typical electricity consumption (TEC) values being far below the regulatory standard values*2. Moreover, the time required to recover from sleep mode has been reduced by 48% from that of the previous model*3 to 5.2 seconds.
The major improvements include adoption of the QSU technology (DH fixing system) for the first time for a black-and-white multifunction printer for efficient heating to the fixation temperature. Further, the conventional data reading timing has been improved to minimize the extra time needed for motor drive control. Moreover, by use of the low-friction grease developed jointly with a chemical company, gear loss has been reduced by 40%, which has also helped reduce noise and foster energy conservation. In fact, the RICOH MP 2554 is the first in its class (machines that can print up to 25 pages per minute) to limit copying noise to below 60 dB. Environmental performance has also been increased by enabling the use of thinner paper (53 g/m3) to save resources as well as by using recycled plastics and bioplastics as materials to ensure compliance with the Japanese Act on Promoting Green Purchasing and conformity with the Eco Mark criteria.

As much as 229% below the fiscal 2017 standard values set under the Japanese Act on the Rational Use of Energy (enforced on March 1, 2013) and 284% below the TEC standard values (Ver.2) of the International Energy Star Program enforced in January 2014.

The "RICOH SP 6410/6420/6430/6440" A3 black-and-white printers released in February 2015 are designed to be compact and eco-friendly machines. They provide high environmental performance and flexible paper handling capabilities with a small footprint while also being highly productive. In developing these smaller and lighter products, we set ourselves the following technical challenge: to suppress rises in temperature inside the printer. To meet this challenge, we set temperature targets for components that have a particular tendency to heat up inside the printer and carried out a series of simulations to optimize airflow inside the machine.
For the internal mechanism, we developed a unique fixation roller that has been reinforced with inner ribbing to prevent it from being deflected. At the same time, we kept the roller as slim as possible. Moreover, by incorporating a duplex unit, we have reduced the footprint of these printers by 18% compared with that of the previous model*, thereby making the machines compact enough to fit on an ordinary desk. Further, as a result of repeated simulations aimed at making the printers stronger and more resistant to shocks and deformations even as we made the resin and sheet metal components thinner, we have decreased the body weight by 20% from that of the previous model.
With regard to energy efficiency, we adopted power-saving application-specific integrated circuits (ASIC) as well as energy-efficient display panels and others. This has resulted in a 24% reduction in the typical electricity consumption (TEC) value. Also, power consumption in the sleep (standby) mode is reduced by about 80% from 2.8W to 0.52W. Moreover, recycled plastics, bioplastics, and other eco-friendly materials are used in the products to boost their environmental performance, including making them compliant with the Japanese Act on Promoting Green Purchasing and meeting the Eco Mark criteria.

Comparison of TEC Values
Ricoh has been pursuing higher environmental performance also for its production printers, which provide flexible paper handling capabilities and are used for high-quality, high-volume printing. Released in April 2015, the RICOH Pro C9110/C9100 printers provide overwhelmingly high productivity. These highly durable, high-speed, and full-color printers boast the industry’s top-class performance in terms of typical electricity consumption (TEC value)*, with the maximum monthly output being set at 1 million sheets. The Pro C9110/C9100 printers have met Japan’s Eco Mark and U.S. EPEAT Gold criteria, and there are no other production printers that have achieved a color printing speed of 110 pages or more per minute while meeting the International Energy Star standards.
The printers are thus highly energy efficient thanks to the energy conservation technologies and space-saving designs developed by Ricoh as well as the paper cooling mechanism that adopts a highly efficient liquid-cooling method, also developed in-house. Compared with the conventional method of employing two air-cooling devices, power consumption has been reduced by 46% as a result of using this mechanism.
On-demand printers, such as production printers, offer a wider range of benefits than offset printing machines. These include waste reduction achieved by printing only in the necessary quantity; elimination of the need for high-volume test printing; and no use of ink and the generation of no waste liquid. In addition to these environmental advantages, Ricoh has further pursued the reduction of environmental impact throughout the life cycles of its production printers by such measures as drastically reducing the use of packaging materials in the delivery of the products. Through these measures we aim to become the industry’s No. 1 in terms of both productivity and environmental performance.
