摘要： A metering skive for a dry electrophotographic (EP) printer is mounted on a retractable skive mount. The skive mount is spring-loaded to a mounting block, and a stop pin sets the distance between the skive mount and the mounting block. A movable spacer with a plurality of laterally-separated regions of respective, different thicknesses is mounted between the head of the stop pin and the mounting block. A retractor can be operated to pull the skive mount towards the mounting block so the spacer can be moved to select a desired spacing between the mounting block and the skive mount, and thus a desired gap between the metering skive and the toning member in the printer.

摘要： Correction data is produced for density errors in prints produced using a printer. While printing a test image, the periods of rotation of one or more rotatable imaging members arranged along a receiver feed path in the printer are measured using respective period sensors. The printed test image is measured in both the cross-track and in-track directions and a two dimensional map of the one or more period sensors is determined. A reproduction error signal representing deviation from aim density is determined. The variations from the data at measured periods in one or both directions are used to produce a correction signal.

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.

摘要： Methods are provided for automatic cross-track density correction for a print engine having a print head that forms lines of picture elements on a receiver based upon lines of pixel values. In one aspect of the method, the print engine is caused to print a first print having a plurality of different areas along a cross-track direction with target densities and data is received from which measured densities for different ones of the plurality of different areas can be determined. A line density adjustment function is based upon a functional relationship between a cross track position of different ones of the areas and a difference between the measured density and the target density at the different ones of the areas. A production print is subsequently printed according to lines of pixel values for the production print modulated by the line density adjustment function.

摘要： Methods are provided for controlling airflow across a width of a charger support area having a charger housing supporting a corona charger that is proximate to a primary imaging member. In one method, a flow of air is provided proximate an inlet side of the charger housing area and a deflection surface is used to deflect the flow of air from a first direction to a second direction leading to an impact surface against which the flow of air is disbursed. The impact surface is outside of the width of the charger housing so that the air flow can supply a volume of disbursed air into the charger housing and primary imaging member that is sufficient to create a pressure that causes the disbursed air to move to an outlet on an opposite side of the area without directly exposing the charger or the primary imaging member.

摘要： A multi-component duplex print is produced on a receiver. Master print engines and slave print engines synchronized to the masters are arranged along the transport path of the receiver with inverters between them. Each inverter has an inverted travel path and a non-inverted travel path, and a difference of a travel time of the receiver in the inverted travel path of each inverter as compared to a travel time of a receiver in the non-inverted travel path of that inverter is adjusted to be an integral multiple of a period between successive receivers. A received job specification designating a first assigned one of the print engines to print on a first assigned side of the receiver. A controller sets the positions of the inverters so the first assigned side of the moving receiver is the corresponding print side of the first assigned print engine.

摘要： Printers and cleaning systems are provided. A cleaning system has an actuator that moves the electrostatic imaging member in a second direction opposite the first direction and a frame positions a mounting within a first range of mounting distances from the electrostatic imaging member with the mounting holding a cleaning blade at a holding angle that causes a free length of the cleaning blade to extend along a first direction to position a cleaning end of the cleaning blade to engage the electrostatic imaging member for movement therewith. The electrostatic imaging member urges the cleaning end in the second direction to deflect the cleaning blade to extend along the second direction to position the cleaning end to wipe the electrostatic imaging member and the free length, the holding angle and the working angle cause the cleaning edge to wipe at a working angle between about 85 and 89 degrees.
