Multicolor electrophotographic print engine

Abstract

A method and system for printing image documents using a variety of toners where some toners using a multi-development station having two or more development stations. These toners are co-printed prior to fixing, on the receiver by the multi-development station.

Description

technical field [0001] This invention relates to electrophotographic print engines. More specifically, the present disclosure describes an apparatus capable of printing images utilizing multiple development stations. Background technique [0002] To produce a print using an electrophotographic device, the primary imaging member - also called a photoreceptor or photosensitive conductor - is first charged uniformly. An electrostatic latent image is then formed by imagewise exposing the charged primary imaging member using known methods such as exposure systems, LED arrays, or laser scanners. The primary imaging member is then placed in close proximity to a development station containing charged marking particles, commonly referred to as toner or dry ink, so that the marking particles selectively adhere to the electrostatic latent image, thereby converting it into a visible image . The image is then transferred to an intermediate transfer member or directly to a receiver. T...

Problems solved by technology

Therefore, it is generally difficult to transfer an arbitrarily large number of toner layers, as opposed to lithographic printing where an arbitrarily large number of offset offsets

[0010] Finally, the space available for electrophotographic print engines is often more constrained than that available for offset printing
