Embodiment Construction

[0025] FIG. 2 is a system layer view of the electrophotographic printer 20 . In the embodiment of FIG. 2 , an electrophotographic printer 20 has an electrophotographic print engine 22 that deposits dry toner 24 to form a toner image 25 in a patterned arrangement of toner stacks. Toner image 25 may include any patterned application of toner 24 and may be conformed to data representing text, graphics, photographs, and other types of visual content and based on the desired structure or function of applied toner 24 The pattern mapping determined by the sexual arrangement.

[0026] Toner 24 is a material or mixture that contains toner particles and is capable of forming a Image, pattern or coating. As used herein, "toner particles" are marking particles used in electrophotographic print engine 22 to convert latent electrostatic images into visible images. The toner particles may also include transparent particles, which may, for example, provide a protective layer on the image o...

Abstract

Systems for folding a receiver having a dry toner thermally fused thereon are provided. In one aspect, a system for folding has a wetting system adapted to apply water along a fold line and a fold mechanism folding the receiver along the fold line. The folding is performed after a predetermined absorption period during which at least a portion of the applied water is absorbed by the receiver to reduce the extent to which the receiver cracks proximate the fold line during folding.

Description

technical field [0001] This invention relates to methods and apparatus for folding fused electrophotographic prints. Background technique [0002] Electrophotographic printing requires the precise placement of many highly charged toner particles in close proximity to each other, first on a photoreceptor, and then transferred as a toner image to paper or other receiver. The toner image is finally fixed to the paper through a process called fusing. Generally, fusing involves applying heat and optionally pressure to a receiver so that the toner on the receiver heats to the glass transition temperature and bonds to the receiver. The heat and pressure applied during fusing makes the toner image formed on the receiver more rigid and less flexible. [0003] When the end product of an electrophotographic printing system is a printed document and the printed document is a valuable item, sufficient value can be added by turning the printed page into a finished product. This convers...
