We developed a new multi-purpose heating head. It resembles the traditional thermal printhead which has the resistive heating element on the ceramic substrate. Some differences are that it has a continuous resistive element while the printhead has an array of individual independent resistive element heating dots. Consequently, the methods to energize two devices are different. The most significant difference is that it has the heating element on the back side of the ceramic substrate and the media contact is on the front side of the substrate. This unique structure solves many problems which have been difficult and costly to deal with in the traditional structure. Heating element abrasion is no longer a problem as the media is not in contact with the heating element side. The heating element protective over-coating layer is not needed. Other benefits are the even temperature distribution throughout the heating head and easiness of manipulating the heating characteristics of the heating element. A family of heating heads using this idea has been made from small to large format. The new concept product is suitable for thermal rewritable printer erase head, thermal re-transfer printer heating head, pre/post-printing process of printing media and electrophotographic printer toner fuser.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
