The present work describes the investigation of the particle emissions of hardcopy devices (laser printers and multi-function devices) in the current printer operation. The measurements took place under standardized climatic boundary conditions (temperature, humidity and air exchange) in a 1 m3 glass emission test chamber. As measuring instruments a Condensation Particle Counter (CPC) as well as an optical particle counter were used. The results of these investigations show that within the range of 7 nm to 20 µm particle emissions are detectable. The results point on the fact that here beside toner particles also aerosols generated during the printing process can be responsible.
