Abstract: 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.

Abstract: An apparatus and method for cleaning developer from an imaging substrate carry out a plurality of cleaning operations. The apparatus and method first operate to move the imaging substrate in a first direction while delivering cleaning liquid to the imaging substrate.
