摘要:
A process transfers an image from an intermediate imaging member onto a sheet of recording media while preserving the ability to duplex print on the sheet. The process includes generating an image on an intermediate imaging member as the intermediate imaging member rotates in a first direction, synchronizing a sheet of recording media with the image on the intermediate member as the intermediate imaging member continues to rotate in the first direction, transferring the image from the intermediate imaging member onto the sheet of recording media as the intermediate imaging member continues to rotate in the first direction, and limiting release agent on the intermediate imaging member to a level that preserves duplex printing capability on the sheet of recording media.

摘要:
An image forming system and method of using the system includes a development station for developing an image, a replenishing source that stores toner mixed to a desired color and comprising at least two toner component colors, a conditioning station that conditions the toner before sending the toner to a developing station, and a drawing device that draws a portion of the toner in the conditioning station. The drawing device will remove a portion of at least one component color of the toner until the desired color is suitable for developing. The system and method will help to produce images of a desired color in liquid immersion development of color prints. With the use of the drawing device, consistent colored images can be achieved while reducing waste of toner.
摘要:
A system and method for color mixing control in a developing material-based electrostatographic printing system. A developing reservoir containing an operative solution of customer selectable colored developing material is continuously replenished with selectively variable amounts of basic color components making up the operative solution by controlling the rate of replenishment of various color components added to the supply reservoir. An optical sensor is used to measure the optical spectrum of the developed image so that the actual optical spectrum thereof can be brought into agreement with a target optical spectrum associated with a customer selectable color. The present invention may be used to mix a customer selectable color in situ, whereby approximate amounts of primary color components are initially deposited and mixed in the developing material reservoir and the resultant developed image is monitored and adjusted until the mixture reaches a target optical spectrum. An additional optical sensor may be used to control and maintain the color of the developing material in the reservoir through continuous monitoring and correction in order to maintain a particular ratio of color components in the reservoir over extended periods associated with very long print runs.
摘要:
An image data adjustment system is described which adjusts image data to be printed based upon the level of contaminants detected in the toner reservoirs. The system detects the level of contamination of a toner to be printed and adjusts the image data so that a compensating toner is also printed with the desired toner so that an intended print color is achieved despite contaminants in the toner.
