Reducing Indoor Air Emissions from Dry-Process Photocopy Machines

摘要

The paper discusses reducing indoor air emissions from dry-process photocopymachines. These emissions include: volatile organic compounds (VOCs), ozone, and particles. By measuring emissions in a large test chamber, reviewing the literature, and interacting with industry, the authors have been able to identify a number of potentil pollution prevention approaches for reducing emissions from dry-process photocopy machines: (1) formulating toners using high purity raw materials and state-of-the-art manufacturing processes; (2) using a charged roller system (rather than electrically charged corona wires) to reduce ozone emissions; (3) minimizing the need for and/or improving equipment maintenance to improve machine performance; (4) reducing the temperature of the fusing operation to reduce the volatilization of VOCs from the toner; and (5) improving the transfer efficiency of the toner to the paper to minimize toner emissions.
