  • Patent number: 8892005
    Abstract: Printer charging blades and printers are disclosed. An example charging blade for a printer includes an insulating layer to contact a photo imaging surface at an angle to apply pressure to the photo imaging surface, the pressure to control an amount of material present on the photo imaging surface, and a conductive layer attached to a side of the insulating layer, the conductive layer to be charged and to apply a first charge to the photo imaging surface.

  • Patent number: 8488988
    Abstract: Printers and apparatus to reduce emissions from a print substrate exit port are disclosed. An example apparatus to reduce emissions from a print substrate exit port includes a first member coupled to a hinge adjacent a printer substrate exit port, the first member to substantially cover a travel path of a print substrate in a first position and to pivot from the exit travel path of the print substrate in response to air pressure associated with the print substrate when the print substrate travels through the print substrate exit port.

  • Patent number: 8325388
    Abstract: A system and method is disclosed for embedding information in a printed media. The method discloses using a print production system to apply a first set of physical structures for carrying a first data stream onto a media; and using the print production system to apply a second set of physical structures which both carries a second data stream onto the media and also performs at least one other print production function. The system discloses a printing mechanism for applying a first set of physical structures modulated by a first data stream onto a media, thereby creating a printed media; and a coating mechanism for applying a second set of physical structures modulated by a second data stream onto the printed media, thereby creating a coated printed media.

  • Publication number: 20110279866
    Abstract: The present invention is drawn to a method of processing a print job. The method includes encoding a print job post-print processing instructions. The method additionally includes printing the print job including the post-print processing instructions on a media substrate. The post-print processing instructions can be printed with a non-visible ink. The post-print processing instructions can be read, and the post-print processing can be performed according to the instructions.

  • Patent number: 7850274
    Abstract: Printers and methods to reduce vapor emissions in printers are disclosed. An example printer is described, including a fan to urge an airflow from a first printer portion, a duct to direct the airflow from the first printer portion and to substantially prevent adding air to the airflow, a condenser in communication with the duct, the condenser comprising a first condensing fin to condense oil in the airflow into a liquid, and an airflow reflection reducer associated with the condenser to reduce reflection of the airflow off of the first condenser fin.
