20100111559 | TONER REMOVAL APPARATUS FOR ELECTROGRAPHIC PRINTER - A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. The web-cleaner has two wiper blades, including one or more blades, each having a distinguishment such that the distinguishment distinguishes one wiper blade from the other wiper blade when the blades are locked into the cleaner sump by springs, to facilitate material removed from the web. The wiper cleaning blades are held using a shoe that comprises a “T-shaped” extrusion wherein the extrusion has a rigidity to reduce shoe deformations. | 05-06-2010 |
20120207509 | ELECTROPHOTOGRAPHIC PRINTER WITH DUST SEAL - An electrophotographic printer includes a rotatable photoreceptor adapted to receive dry toner and a rotatable toning member arranged with respect to the photoreceptor to supply toner thereto. A seal includes a complaint contact member and a non-contact member. The contact member is arranged in mechanical contact with the photoreceptor. The non-contact member is spaced apart from the surface of the toning member by a selected non-zero distance, the selected distance being greater than zero. This reduces dusting. | 08-16-2012 |
20120224899 | ELECTROPHOTOGRAPHIC PRINTER AND CLEANING SYSTEM - Cleaning systems for an electrostatic imaging member and printers having cleaning systems are provided. In one aspect, a cleaning system has a wiper, a mounting holding the wiper so that an extension length of the wiper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the wiper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the extension length with the wiper resiliently bending to fit within the extension distance to define a working angle. The extension distance is within a range of extension distances that cause the working angle to be within a range of working angles that are greater than a range of working angles associated with a greater range of extension distances. | 09-06-2012 |
20120275814 | ELECTROPHOTOGRAPHIC PRINTER WITH CHARGING-ROLLER CLEANER - An electrophotographic printer includes a rotatable member and a carriage rotatable around an axis. Two rotatable chargers are mounted on the carriage, each for charging the rotatable member. A carriage drive rotates the carriage to bring the first charger into contact with the rotatable member and the second charger into operative arrangement with a cleaner, or vice versa. A charger drive rotates the charger in operative arrangement with the cleaner at a speed greater than a selected speed or with a torque greater than a selected torque, and the rotatable member rotates the rotatable charger in contact therewith at the selected speed with the selected torque. | 11-01-2012 |
20120301197 | CLEANING BLADE MEMBER AND APPARATUS WITH CONTROLLED TRIBOCHARGING - A cleaning system has a composite photoreceptive imaging member having a support layer, an electrically conductive layer interfacing with the support layer, a photoconductive charge generation layer interfacing with the electrically conductive layer and generating charge holes and electrons in response to exposure to electromagnetic radiation; a charge transport layer that allows charge holes to migrate from the charge generation layer to the outer surface while resisting migration of electrons from the charge generation layer to the outer surface and a cleaning blade member having a cleaning surface layer against the electrostatic surface to at least in part remove toner and debris from the outer surface. The cleaning surface layer has a first material and a second material that are combined in proportions that cause a triboelectric charge to be formed on the outer surface having a difference of potential of between zero and minus 20 volts. | 11-29-2012 |
20130028644 | ELECTROPHOTOGRAPHIC PRINTER AND CLEANING SYSTEM WITH SCRAPER CLEANING SYSTEM - Electrophotographic printers and cleaning systems for an electrostatic imaging member are provided. In one aspect the cleaning system has a scraper a mounting holding the scraper so that a free length of the scraper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the scraper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the free length with the scraper resiliently deflecting to fit within the extension distance to define a working angle where the scraper contacts the electrostatic imaging member. The extension distance is within a range of extension distances that cause the scraper to have a working angle that is within a range of working angles are greater than the working angles of an alternative range of working angles if the scraper were to be positioned within an alternative range of extension distances that is greater than the range of extension distances. | 01-31-2013 |
20130256362 | REPLACEABLE COVER FOR BARS IN A PRINTING SYSTEM - A bar for a web transport system in a printing system can include a first set of pins extending outward from an exterior surface of the bar and a replaceable cover wrapped over at least a portion of an exterior surface of the bar. The replaceable cover includes a plurality of openings at one end of the cover with at least a portion of the openings positioned at the locations of respective pins. Fasteners attached at another end of the cover are adapted to removably attach the cover over the bar. | 10-03-2013 |

20140019944 | Automated Identification of Redundant Method Calls - Embodiments of the invention may provide for collecting specified data each time that a call to a given method occurs, wherein a given call to the given method is associated with a set of arguments comprising one or more particular argument values for the given method, and the collected data includes an element uniquely identifying each of the particular argument values. The process may further include storing the collected data at a selected location, and selecting a call threshold for the given method, wherein the call threshold comprises a specified number of occurrences of the given call to the given method, when the program is running. The collected data may be selectively analyzed at the storage location, to determine whether an occurrence of the given call to the given method has exceeded the call threshold. | 01-16-2014 |
