Laser Printer Health Risks?

May 16th, 2008

Reader’s Question:

I read something somewhere about the findings that show that researchers have found that laser printers are responsible for a significant amount of potentially carcinogenic emissions? Is this true?

According to a recent study some printers emit sub-micrometre particles which some suspect may be associated with respiratory diseases. It is said according to the study that 17 of the strongest emitters were made by Hewlett-Packard and one by Toshiba. However, the machine population studied, was only those machines already in place in the building and was thus biased toward specific manufacturers. It was noted that particle emissions varied substantially even among the same model of machine. According to Professor Morawska of Queensland University the health effects from inhaling ultrafine particles depend on particle composition, but the results can range from respiratory irritation to more severe illness such as cardiovascular problems or cancer

Also a study in Japan found that laser printers increase concentrations of styrene, xylenes, and ozone, and that ink-jet printers emitted pentanol.
