摘要： Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0.5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor. The elastomeric transfer roller is heated to from 50 degrees Celsius to 100 degrees Celsius. Subsequently, the image is transferred to plain paper through a nip formed between a backup roller under pressure with the transfer roller. The release layer of the photoreceptor has a surface energy which is less than a surface energy of the elastomeric transfer roller which in turn is less than a surface energy of the liquid ink which in turn is less than a surface energy of the plain paper.

摘要： An apparatus and method for removing excess developer liquid from an imaging substrate make use of a squeegee roller, and a mechanism for loading the squeegee roller against the imaging substrate. The squeegee roller removes the excess developer liquid from the imaging substrate at an upstream side of the squeegee roller relative to a direction of movement of the imaging substrate. A portion of the excess developer liquid can pass to a downstream side of the squeegee roller, however, and be transferred from the squeegee roller to the imaging substrate. A second developer liquid removal mechanism is provided to remove from the imaging substrate the portion of the excess developer liquid transferred from the squeegee roller. The second developer liquid removal mechanism may include a second squeegee roller mounted at a position adjacent the downstream side of the first squeegee roller. The second squeegee roller can include first and second squeegee sections that contact the imaging substrate at positions outside of the imaging region. The second squeegee roller can be driven in a direction opposite to the direction of movement of the imaging substrate to effectively remove the excess developer liquid.

摘要： A testing procedure and method is provided for assessing the quality or acceptability of performance of individual liquid ink electrostatic toners on individual receptor surfaces. An approximately standard drop of the individual liquid toner is placed on the receptor to be tested. The drop is pressed onto the receptor and spread on the surface of the receptor (preferably before the drop has had time to partially evaporate or to have the liquid in the drop absorb or naturally spread on the receptor surface) under controlled conditions. The characteristics of the spread drop on the receptor surface are measured, and the characteristics are compared to parameters defining the characteristics expected from a liquid toner that define acceptable performance between toner and receptor. In this manner the relative performance of individual toners on individual receptor surfaces can be evaluated independent of electrostatic effects. This can be important, as the electrostatic effects bring another parameter of performance into evaluation of the compatibility of the toner and receptor and can misdirect research for adjusting their compatibility.
摘要翻译：提供了一种测试程序和方法，用于评估单个液体静电调色剂在各个接收器表面上的性能的质量或可接受性。将单个液体调色剂的大致标准滴放置在待测试的受体上。在受控条件下，将滴落在受体上并扩散在受体的表面上（优选在滴下已经有时间部分蒸发或使液滴中的液体吸收或自然扩散在受体表面上之前）。测量受体表面上扩散滴的特征，并且将特性与限定从调色剂和受体之间确定可接受性能的液体调色剂预期的特征的参数进行比较。以这种方式，可以独立于静电效应来评估各个调色剂在各个受体表面上的相对性能。这可能是重要的，因为静电效应将性能的另一参数带入评估调色剂和受体的相容性，并且可以误导调查其相容性的研究。
