摘要:
Toning apparatus for toning an electrostatic latent image, having image and background portions at different potentials on an imaging surface. The apparatus comprises an endless toning surface coated with a layer of concentrated toner and engaging the imaging surface at a toning region. The apparatus additionally comprises a source: of voltage connected to the toning surface and electrifying the toning surface to a voltage operative to selectively transfer at feast a portion of the layer to image: portions on the imaging surface. A developed mass per unit area (DMA) controller having an input indicative of the DMA on the imaging surface is operative to adjust the DMA on the toning surface in response to the input.
摘要:
A method of automatically optimizing a printing apparatus based on media type of a substrate, comprising: (A) inputting a substrate into the printing apparatus; (B) determining the media type of the substrate; (C) automatically adjusting calibration settings according to at least one calibration setting preset, responsive to the determining; and, (D) performing image transfer.

摘要:
Imaging apparatus including an imaging surface having a toner image formed thereon and an intermediate transfer member, which receives the toner image from the imaging surface and from which it is subsequently transferred. The intermediate transfer member includes a drum having mounting recesses formed therein and an intermediate transfer blanket mounted on the drum. The blanket has a layered transfer portion having a transfer surface on one face thereof which receives the toner image and optionally an adhesive layer on the opposite face thereof and a mounting fixture, attached to one edge of the layered transfer portion and adapted to mate with the mounting recesses in the drum, whereby the transfer blanket is fixedly and removably mounted on the drum.
摘要:
A multi-layered image transfer blanket and a method of producing same, including a body portion and an image transfer portion, the image transfer portion having an image transfer surface and a back surface, comprising forming the image transfer portion on a carrier substrate and transferring the image transfer portion onto the body portion such that the back surface of the image transfer portion faces the body portion. Preferably, the image transfer portion is formed on the carrier substrate such that the back surface of the image transfer portion faces the carrier substrate.
