In a copier employing a liquid developer material, it is necessary to control the dissemination of the solvent to the surrounding environment. The liquid developer is a mixture of toner particles in a solvent, such as an aliphatic hydrocarbon, i.e. an Isopar. The toner particles are used to develop the latent image and the solvent contaminates the environment or is reclaimed for recycling. In order to reclaim the solvent, it must be trapped and accumulated. One way to trap and accumulate the solvent is through the use of an absorbent roll or wick. The wick is positioned in the desired location and suction is applied thereto to draw the solvent through the wick to the reclamation system. Some areas where wicks of this type may be located are after imaging and before transfer, on the copy sheet after transfer and before fusing, and to assist in cleaning. The wick or roll is designed to be disposable with the housing that the wick is mounted in being coupled to a vacuum system. Properly spaced, the wick could be used to capture solvent on the edges of the photoreceptor, outside of the image area, or even over the image area, just prior to transfer.
