This presentation highlights a specific case of toner plasticization that occurred during a storage situation. Three aspects of the investigation are discussed: determination of the root cause, analytical results with a correlation to functional testing, and the development of an offline materials compatibility screening test. Once the contaminant causing a change in toner properties was identified, functional testing and materials analysis confirmed a strong correlation. After the realization that coating materials from any location within the EP system could potentially interact with toner in an undesirable way, an offline materials compatibility test was developed. It is anticipated that this test method could provide a screening tool for low risk materials for use in EP subsystems.
