  • Metering apparatus for electrophotographic printer
    Patent number: 8509637
    Abstract: 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.

  • Apparatus for facilitating handling tab stock in a top feed vacuum corrugated feeder
    Patent number: 5876030
    Abstract: An apparatus for facilitating handling particularly tab stock in a sheet feeder, having a top feed vacuum corrugated feed head assembly for feeding sheets seriatim from a sheet supply stack. The facilitating apparatus includes a platform adapted to support a sheet supply stack of the tab stock type. A tab stock sheet supply stack is located on the platform in relation to the top feed vacuum corrugated feed head assembly. A force is applied to the tab stock sheet supply stack, such force having at least a component in a direction relative to such tab stock sheet supply stack to prevent individual tab stock sheets in such stack from prematurely moving out of control of the top feed vacuum corrugated feed head assembly.
