A sheet stripping device for stripping copy sheets from an arcuate imaging surface, including a support element and an electrically conductive stripping element coupled to an electrically biasing source. An electrical bias is applied to the stripping elements or fingers to suppress the build-up of toner on the stripping element so that large concentrations of toner are eliminated and minimal residue is left on the fingers as a thin film for preventing background contamination of the copy sheet.

Electrically biased sheet stripping apparatus

The invention relates to a liquid dispensing apparatus suitable for use in the fuser of an electrostatographic recording machine such as, for example, a xerographic copier or a printer. The apparatus includes a trough (41), a wick (100) extending along its length and a roller (47) in contact with the wick (100). A metering blade (49) is located adjacent the roller (47) in such a manner as to scrape off excess liquid from the surface of the roller (47), the metering blade (49) being disposed relative to the wick (100) such that the excess liquid falls on the wick (100) thereby ensuring saturation of the wick (100). Return paths for the excess liquid are provided between the wick (100) and the wall of the trough (41) so as to prevent build up of the excess liquid above the wick (100).

Liquid dispensing apparatus

A reproduction machine has a photoconductive surface and a stripping device for separating the leading edge of a transfer sheet from the surface. Located adjacent to the stripping device is a guide which is maintained at a reference voltage such that an electrostatic attraction is set up between the guide and the transfer sheet so as to draw the latter toward the guide. A support member generally uniformly separated from the guide serves to support the transfer sheet in the event the electrostatic attraction is insufficient to draw the transfer sheet to the guide. Either the guide or the support member may be at least partially covered by a layer of insulating material.
