Abstract: A printing system using a recharge, expose and development image on image process color system in which there is an optional gloss development step is employed that results in the image having an uniform gloss and toner pile height. The printing system may be a single pass system where all of the color are developed in a single pass or a multi-pass system where each color is developed in a separate pass. The additional gloss development step results in optimal color quality.

Abstract: The predominant language of a sample text is automatically identified using probability data that include N-gram probability data for at least one language and word probability data for at least one language. The N-gram probability data of a language indicate, for each N-gram, the probability that it occurs if the language is predominant. Similarly, the word probability data of a language indicate, for each word, the probability that it occurs if the language is predominant. The probability data are used to automatically obtain sample probability data for at least two languages. The sample probability data include N-gram probability information for at least one language and word probability information for at least one language. The sample probability data are used to automatically obtain language identifying data identifying the language whose sample probability data indicate the highest probability. The N-grams can be trigrams, while the words can be short words of no more than five characters.

Abstract: A method for purging an ink jet print head to clear ink jet orifices is provided. A purge cap forms a vacuum seal over the orifice plate of the print head. Multiple low pressure differential vacuum pulses are applied to the purge cap to remove debris and trapped air bubbles from the ink jet orifices. The low pressure pulses avoid cavitation inside the print head and reduce the amount of ink expelled during the purging process.

Abstract: A method of treating an electrostatographic imaging member web is applied to a web that includes a support substrate and at least one imaging layer formed over the support substrate. The electrostatographic imaging member web can optionally include no anti-curl backing layer. The web is bent into an arcuate shape and heated to a temperature above the glass transition temperature of the imaging layer. The imaging layer is then cooled while in the arcuate shape to a temperature below the glass transition temperature, forming a substantially stress-free imaging layer when conforming to the arcuate shape. The electrostatographic imaging members can be electrographic and electrophotographic imaging members. The treated electrostatographic imaging member webs can be formed into seamed electrostatographic imaging member belts such as ionographic imaging member belts and photoreceptor belts.

Abstract: A full-color image capture system includes a color separation element and a single image sensor array. The color separation element can be operated in either a light reflective (mirror) mode in which selected intrinsic colors are reflected onto the image sensor array, or a light transmissive (filter) mode in which selected colors are transmitted to produce subtractive primary color images. The color separation element can be formed of holographic polymer dispersed liquid crystal materials that reflect light of selected intrinsic colors. The color separation element can include three holographic polymer dispersed liquid crystal material layers so that three different intrinsic colors can be selectively reflected or transmitted onto the image sensor to provide a full-color image.

Abstract: An apparatus which develops an electrostatic latent image recorded on a photoconductive member used in an electrophotographic printing machine.
