A new toner-based electrographic development process is presented, which we call “Momentum-Control Scavenge-less Jumping Development” (MC-SJD). It is similar to conventional jumping development in that an AC waveform is used to drive charged toner particles across a small gap from a toned donor roll towards a photoreceptor with a latent electrostatic image. Rather than allowing toner particles to impact the photoreceptor and potentially damage any existing toned image, a four-phase waveform is used to reduce the normal component of the toner's momentum prior to its impact with the photoreceptor. The toner thus forms a nearly static cloud of charged particles near the latent image, which then gently develops onto the photoreceptor. The MC-SJD process is equally applicable to both single and dual-component development subsystems. This approach is particularly useful for image-on-image color printing architectures, but may also help improve the image quality of monochrome and conventional color prints.

  • 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.
