In the interest of improving indoor air quality, an investigation was performed to develop methods for determining ozone (10028156), particulate and volatile organic compound (VOC) emission rates from laser printers, and to provide emission rates for some printers. Four different printers were tested in a validated environmental chamber. Significant levels of ozone were produced by older printers which used a corona wire. Maintenance of these older printers' ozone filters tended to reduce the generation of ozone during operation. The new printers which used a charged roller rather than a corona wire produced little ozone. For all printers the amount of particulate produced was extremely low. However, particulate generation during the toner cartridge replacement operation was not evaluated, nor was there any attempt made to consider the possible particulate generation caused by the use of different printer papers. The volatile organic compounds produced were butanol (71363) and xylene (1330207). The significance of these was dependent on the other sources of VOCs available. The author concludes that the information generated in this study will assist with sizing a building's heating, ventilation, and air conditioning system, and thereby maintain acceptable levels of indoor air quality.
