Fuji Xerox Begins Production of Energy-Saving
EA-Eco Toner to be Used in New Mainstay Products
from Spring 2008

Reduces Power Consumption During Toner Fusion by up to 40 Percemt,
Helping Cut CO2 and Prevent Global Warming

TOKYO, December 25, 2007 ? Fuji Xerox Co., Ltd. has developed the energy-saving EA-Eco toner, which can be fused to paper at a temperature more than 20 °C lower than conventional EA (Emulsion Aggregation) toner, resulting in up to a 40 percent reductionNote: 1 in power consumption during fusion.

To produce the new toner, Fuji Xerox Imaging Materials Co., Ltd. constructed a third wing with an investment of approximate 10 billion yen at its plant exclusively to manufacture EA toner. A ceremony to celebrate the completion of the wing is held on December 25 to start mass production. Once up and running, production capacity of EA toner will increase from roughly 5,000 to 8,000 tons a year.

EA-Eco toner will be used in Fuji Xeroxs core products planned to be launched in spring 2008, and then sefquentially expanded to other new products.

To produce the EA-Eco toner, newly developed polyester that has different characteristics including different melting point is mixed with other materials, thereby enabling to lower a fusing temperature more than 20 °C comparing to traditional EA toner. Power consumption during fusion can thus be reduced by 20 percent, or up to 40 percent in glossy mode.

Toner fusion is the most power-intensive process in copy / multifunction devices, accounting for 50 to 80 percent of total power consumed. By employing EA-Eco toner, power consumption of the devices when used can be slashed by around 15 to 30 percent.

The EA-Eco toner fuses firmly to paper, realizing optimal toner fusing, melting and stripping processes not to blemish next sheet with remained toner inside the fuser. Fused toner surface is smooth, achieving glossy, high-quality images nevertheless the toner is oil-free. Further, the EA-Eco toner realizes an appropriate level of glossy finish for different paper types, such as plain copy paper, coated paper and art paper. Thus, it has achieved both low power consumption and high-quality printing.

Fuji Xerox plans to employ the EA toner in all new office copy / multifunction devices. Starting operation of the Fuji Xerox Imaging Material’s first wing in April 2001, the company first used the toner in the DocuCentre Color 500 / 500 CP, digital color multifunction devices, in September 2001. Since then, Fuji Xerox has employed the EA toner in its core digital color multifunction devices and printers in sequence.

The second wing of the plant became operational in December 2005, expanding production capacity to around 5,000 tons annually, more than double of that in 2004. In line with a forecast of continued demand, Fuji Xerox decided to develop new EA-Eco toner that can achieve both environmental burden reduction and high-quality printing, followed by construction of the third wing.

As part of its manufacturing strategy, Fuji Xerox has been transferring assembly lines to China, while manufacturing such products as publishing systems, high-speed printers for mission-critical systems as well as toner in Japan. This is because toner production requires special equipment with advanced technologies as well as to flexibly respond to customers' daily demands.

Fuji Xerox seeks to develop products with less environmental load while enhancing image quality.

Characteristics of EA-Eco toner

In contrast to conventional pulverized toners, EA toner is produced using Emulsion Aggregation method, in which resin, pigment, and wax particles are aggregated to form toner particle in wet process (in water). With this method, uniform particles with a size of 5.8 micrometers each (average particle diameter) can be manufactured.
The manufacturing process differs from the pulverized toners in that the size of the pigment and latex particles is increased rather than minimized, making it possible to cut CO2 emissions by 35 percent because of less procedures. The shape of the particles can be controlled with precision by employing this method, thus enabling images to be more efficiently transferred and fused to paper, reducing the amount of toner used by 37 percent.
As the toner particle contains wax inside, it does not need oil when fused, enabling to be transferred evenly and thinly. As a result, it is easier to annotate and attach self-adhesive notes, while also enhancing the clarity of fine lines. In addition, photos and graphics appear much more natural controlling glare.
In addition to these features, the EA-Eco toner comprises of new materials and is formed with a new structure to comprehensively reduce environmental burden, leading to lower fusing temperature by 20 °C to 50 °C compared with conventional toner. Being oil-free, it can realize a level of glossy finish appropriate for different types of paper. It therefore meets a wide range of needs, from the office to printing fields.
