  • Patent number: 7831164
    Abstract: A method of controlling gloss in a printing system having a fuser. The method includes: creating a gloss look-up table for temperature settings; using the look-up table for temperature settings to determine a desired gloss range; measuring an actual gloss range on a substrate continuously with an in-line gloss meter; and determining whether the actual gloss range is within the desired gloss range. Where the actual gloss range is outside the desired gloss range, the temperature settings of the fuser are adjusted.

  • Patent number: 7829251
    Abstract: Disclosed herein is a flexible imaging member having a high concentration of a charge transport compound having optimum enhanced mechanical and electrical characteristics. By increasing the concentration of the charge transport compound to a level of from about 55 weight percent or more, including from about 55 weight percent to about 70 weight percent, and from about 55 weight percent to about 65 weight percent, a flexible imaging member can be produced with reduced residual voltage and/or improved sensitivity. Furthermore, the fatigue cracking resistance of the charge transport layer can be improved through the implementation of a heat stress release process described more particularly herein.

  • Patent number: 7830541
    Abstract: A method for providing a secure fax confirmation page from a facsimile capable device having a user interface includes receiving documents, in the form of a fax job, to be transmitted by the facsimile capable device. After receipt of a recipient's fax number, a determination is made as to whether secure fax confirmation has been selected from the user interface. A passcode is received prior to scanning of the documents. The interface displays a fax job list, which identifies whether a secure fax confirmation page is associated with individual fax jobs. Upon selection of a confirmation page by the operator, the facsimile capable device prints a secure fax confirmation page.
