Shipping and Storage at Elevated Temperature: Studies of Toner Response
Abstract:Driven by a desire to reduce printer power demand by lowering the temperature requirements of the fuser, it has become common for lower softening temperature resins to be employed in toner. One consequence to the use of these resins is an increased risk of blocking during shipping or storage at elevated temperatures. By extended exposure of toner samples to elevated temperatures we propose to identify and evaluate the material characteristics most relevant to robust ship/store performance. As observed previously, low Tg or onset of flow temperatures (Shimadzu) can contribute heavily to temperature induced blocking but are not necessarily a guarantee of ship/store failure. Failure can be accompanied by absorption of surface additives into the toner particle. High levels of additives can significantly improve blocking resistance.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
