Improvement Overview from Ver1.0 to Ver2.0

Criteria have been revised twice, actual TEC values greatly improved. Particularly Ver2.0 criteria are so severe for monochrome products that further improvement is hardly possible.

History of power reduction in Sleep mode

In these ten years Sleep power has been improved greatly. After achieving ~1W, there is no other power source, meaning this is the limit.

• 1. Power off of non-active area
• 2. Main CPU off (separation of LAN connection)

③Separation of network-connection-function from high- speed main CPU, which consumes significant power, by way

• f network-control LSI, realizing energy-saving.

Further

Only chip remains, further reduction is difficult. fuser ◆Technical hurdle

・ASIC development – resource investment ・Retarded recovery time – system initialization ・Efficiency of power unit – high efficiency for

low power output ① ② ①Power off only for fuser unit ②Power off for other units, other than network controller

Crash toner (conventional toner) Emulsion polymerization (capsule toner) Lowering toner melting temperature (example) smaller particle diameter improvement of diameter distribution

Big improvement in manufacturing method (break through) （ remove too big / too small particles）

Toner viscosity change vs. temperature EA-Eco toner with an abrupt change of viscosity against temperature lowers the minimum fusing temperature by 20~50 degrees centigrade. However, this needs enormous investment on production plant etc.

Distribution of MFD TEC data

After introducing technologies shown in the preceding pages, the top TEC values of monochrome and color products stay almost at the same level. This shows that EP method has encountered its technological limit.

Summary

Success! ENERGY STAR has driven tremendous energy savings! Concern For top-runner products; there’s no where to go, but these are now very efficient products.
