CO2 Emissions from Product Usage

Targets and Results for Fiscal 2012 (Product Usage)

Strengthened lineup of energy-saving products

In the area of product usage, Konica Minolta is focusing on its Business Technologies Business, which accounts for over 90% of the total CO2 emissions from product usage, and is pursuing the development of energy-saving product technologies. In fiscal 2012, it strengthened its lineup of products with high energy-saving features, mainly color MFPs, with the release of the bizhub C554 series and bizhub C554e series, both of which can save substantially more energy than previous models.

Energy-Saving Product Design

Example1: Color MFP "bizhub C554e"

The bizhub C554e color MFP boasts one of the world’s lowest power consumption levels. Power consumption during use has been reduced by adopting LED for the scanner light source and further improving the induction heating (IH) fusing technology to increase heating efficiency. Moreover, standby power consumption was cut to a third that of the previous model by implementing finely tuned electricity saving measures during sleep mode. Incorporation of these diverse environmental technologies resulted in a reduction in power consumption of about 39% compared to the previous model *1 (based on TEC *2).

Simitri HD Toner Fuses at a Lower Temperature

Simitri HD Toner is a proprietary polymerized toner developed by Konica Minolta. Polymerization is a method of toner manufacturing that greatly reduces environmental impact during production when compared to conventional toner manufacturing methods. The toner particles are smaller than regular toner particles, so less toner is required for the same print jobs. In addition, the toner is fused at a lower temperature. All of these features contribute to reducing the amount of energy used when the product is in use.

Using IH Technology to Create an Energy-Efficient Fusing Unit temperature

To start printing with an MFP, the fusing roller needs to be heated to a certain temperature. If the standby temperature is kept high, then the roller can be heated quickly to the proper temperature. However, this means that a significant amount of energy is consumed during the standby mode. Reducing this energy consumption is key to making an energy-saving MFP.
Konica Minolta provides a solution with its induction heating (IH) technology. This technology has been applied as the means of rapidly heating the fusing unit of MFPs*. By rapidly heating the surface of the fusing roller, a low standby temperature can be quickly increased to printing temperature. This greatly reduces power consumption during standby mode.

Example3 : AeroDR Cassette digital radiography detector

The AeroDR Cassette digital radiography detector now uses far less power while maintaining image quality and processing capacity as a result of a newly developed IC and a variety of design techniques. Compared to existing models, the AeroDR uses approximately 60% less power when scanning images and approximately 90% less power when on standby.
