This paper explores environmental considerations connected with materials which may be used in desktop electrophotographic toner cartridges. Such considerations include materials constraints, indoor air quality, and end-of-life disposition and recycling. Materials content is constrained both by regulation and public perception. As examples, the issues surrounding carbon black, azocolorants, and heavy metals are discussed. Indoor air quality is an emerging issue of public concern. Measurement of printer emissions is expected to be a growing area of focus within the printing industry. Design-for-Environment (DfE) reduces the environmental impacts caused by a product by altering its engineering design and materials. Some examples of proven DfE applications are presented. One application of DfE is the design of toner cartridges to be recyclable. Design issues surrounding end-of-life returns and recycling will also be explored.
