Characteristics of Ambient Toner Particle Concentrations in a Printing Plant
Derek Gosman, Renmei Xu, Juan Carlos Ramirez-Dorronsoro

Dry toner is a common printing substance used in a wide variety of printing settings – e.g., residential, office, and industrial.The current study investigated the characteristics of ambient particles in a small printing facility.Ambient particles of various sizes, ranging from 0.3μm to >5.0 μm, were sampled usinga CLiMET Model CI-154 Airborne Particle Counter prior to the initiation of printing operations and during peak production hours. Samples were collected at various distances from the printing operations. The results indicate a greater number of particles adjacent to printing operations when compared to baseline samples and those taken farther away from the press. These findings suggest toner-based printers are emitting ultra-fine particles into ambient air.
