Chemical Emissions and Ultrafine Particles
All laser printers emit small amounts of volatile and semi-volatile organic compounds (VOCs and SVOCs) due to the heating of plastic parts, and they produce small amounts of dust (mostly paper remnants) as paper moves through the printer. Emissions from printers in the workplace are subject to occupational exposure restrictions of individual countries for specific chemicals.
Lexmark printers are tested throughout the development cycle for emissions of styrene, benzene, ozone, dust, total and individual volatile organic compounds, and ultrafine particulates according to the protocols of the internationally recognized Blue Angel ecolabel. Results are compared to the Blue Angel limits set forth in the standard, and summary reports are available to customers upon request. No CO2 or other greenhouse gasses are emitted during the printing process as it does not involve combustion. In addition, the majority of Lexmark laser printers emit no more than trace amounts of ozone and all comply with the ozone limits set forth by Blue Angel.
Lexmark owns and operates a Blue Angel-certified and ISO 17025-accredited chemical emission test facility. This allows us to perform official tests for Blue Angel certification and EPEAT. We also conduct additional tests to gain a better understanding of emissions sources and solutions for mitigation.
