An exemplary method can include providing a plurality of particles to be charged and providing a plurality of nanostructures disposed over a first electrode array, the first electrode array including a plurality of electrodes spaced apart. The method can also include providing a multi-phase voltage source operatively coupled to the first electrode array and applying a multi-phase voltage to the first electrode array to create a traveling electric field between each electrode of the first electrode array, thereby causing electron emission from the plurality of nanostructures and forming a plurality of charged particles. The method can further include transporting each of the plurality of charged particles using the traveling electric field onto a surface.

Abstract: A method and system of embossing ink including applying the ink to a print substrate, applying an embossing substrate to the ink wherein the embossing substrate imprints a predetermined pattern into the ink, and curing, via a radiation source, the ink such that an imprint of the predetermined pattern is embossed in the ink.

Abstract: A system and accompanying method for creating a securely printed document using curable toners. The system includes a first radiation source configured to expose a first radiation to a printing substrate having an applied amount of toner, thereby liquefying the toner into a molten state, a curing station, a first feeder configured to feed the printing substrate into the curing station, and a second feeder configured to feed the embossing substrate into the curing station, wherein the embossing substrate comprises a pattern to be imprinted into the toner. The curing station includes a combiner configured to press the printing substrate and an embossing substrate together, a second radiation source configured to expose a second radiation to the combined substrates, and a divider configured to separate the printing substrate from the embossing substrate.

Abstract: An apparatus for loading one or more donor rolls of a developer unit, comprising a developer housing having a reservoir for a developer material, a rotatable first donor roll that delivers the toner onto a moving photoconductive member, a trim roll that receives developer material from the reservoir and delivers the developer material to a first magnetic brush roller that delivers toner to the first donor roll, and a rotatable second magnetic brush roll that receives the developer material from the first magnetic brush roll and delivers the toner to the first donor roll. The apparatus may further comprise a rotatable second donor roll that receives the toner from the second magnetic brush roll and delivers the toner onto the photoconductive member, and a rotatable third magnetic brush roll that receives the developer material from the second magnetic brush roll and delivers the toner to the second donor roll.
