Copiers

Economic Aspects. Table 3 shows that mbber production is the largest market for zinc oxide the downturn in 1980 resulted from a drop in tire production because of the production trend to smaller tires, more importation of tires, and a recession. The drop in paint usage reflects the trend to water-base paints, which originally contained no zinc oxide. However, its growing use in such paints is based upon improved formulations based on zinc oxide. The increased use in agriculture is a result of the realization of the importance of zinc as a trace element. The rise in use of zinc-oxide-coated paper for photocopying is followed by a slackening in use because of a shift to plain-paper copiers. 

HP arsenic is used in the manufacture of photoreceptor arsenic-selenium alloys for xerographic plain paper copiers (see Electrophotography). The level of arsenic maybe 0.5%, 5.0%, or 35% present as arsenic triselenide [1303-36-2] As2Se2. 

The usage pattern in Europe and Japan is more dependent upon the automotive industry. However, with the recent concern about acid rain, the European and U.S. markets should show increased interest in fluorocarbon elastomers for pollution control appHcations. On the other hand, the Japanese market has a sizable outlet in electrical and general machinery manufacturing (eg, copiers). Petroleum appHcations are of Htfle interest outside the United States. 

The XeroX Copier Machine Model A was announced in 1949, and involved compHcated manual operation. Copies of acceptable quaUty were operator dependent. The Copyflo printer, introduced in 1955, was the first automated xerographic machine and enabled the production of copies on a continuous web of ordinary paper. Early electrophotographic products used paper coated with dye-sensitized zinc oxide Electrofax which had met market resistance in terms of aesthetics and cost, so that in 1958 the total market was only about 100 million (1—3,5). 

TT-conjugated. Only classes / and 2 have been used in copiers and printers.

The alloys can be processed into parts requiring hydrolytic and autoclave stabiHty, such as desalinization filter frames and medical devices. Foamed products are used in cabinets for business machines, computers, and copiers. Automotive seat backs are made by blow mol ding and replacements for metal parts by injection mol ding. 

While toner particles were used to exemplify a specific technology and lay the groundwork for discussing the scientific issues surrounding particle adhesion, the topic of particle adhesion extends far beyond copiers. For example, let us consider the fabrication of semiconducting devices. 

United States had at least one PC or computer terminal. The more PCs and computer terminals used m a given building, the greater the impact on the building s energy consumption. The proliferation of personal computers, printers, copiers, and other types of plug loads is the main cause of the rise in energy intensity in recent years. 

Office equipnient is an end use that generally is regarded to consist of five major products personal computers, monitors, copiers, printers, and fax machines. This equipment can be defined by characteristics such as size and speed. Although office equipnient is used in homes, this article focuses on office equipment energy use in actual offices. 

Copier characteristics vaiy with the speed of output, with faster machines adding more sophisticated handling of originals, duplexing, finishing of copies as with stapling and collating, and the ability to make more copies each mouth. 

Off mode The power in this mode is that drawn when the device is switched off (essentially zero), or for copiers when the device is unplug... 

In addition to the power levels above, extra energy is required for each image made by a device. While this varies considerably, a value of 1 Wh/image is common. For copiers, about 10 percent of annual energy use is used for making images, with the other 90 percent primarily used to maintain the copier in the ready to copy mode.
