Abstract

In a liquid xerographic process, the liquid ink inadvertently may be transferred to the image transfer roll during misfeed or other machine failure and may retransfer to the back of subsequent copies. This proposal is directed to a solution to that problem whereby a gravure-type roll, such as a mono-filament wound roll, similar to a liquid xerographic ink applicator roller (see e.g., U.S. Patent 3,993,023), is substituted for the conventional solid surface transfer roll. This transfer roll can be doctored constantly by a flexible blade so that when ink contaminates the transfer roll it will be either doctored away or doctored sufficiently below the "land" level (into the grooves) , so that the ink will not transfer to the back of subsequent copies.
