Abstract

Disclosed is a method for electrically removing an oil film thickness and tacking or binding toner to a photoreceptor or intermediate substrate in a liquid ink development system. By using a corona generator of appropriate electrical polarity in a pre-transfer position, toner may be tacked to the photoreceptor or intermediate substrate. The same corona generator may also function as an electrostatic squeegee to remove liquid from the film. The system employing the disclosed concept is operated in an uphill way providing inclination to the film support substrate that allows for easier handling and collection of the fluid. An advantage of the concept over other schemes is that of being a non-contacting system.

The same corona generator may also function as an electrostatic squeegee to remove liquid from the film. The system employing the disclosed concept is operated in an uphill way providing inclination to the film support substrate that allows for easier handling and collection of the fluid. An advantage of the concept over other schemes is that of being a non- contacting system.

The concept can be used as a stand-alone image conditioning system, an aid to conventional vacuum roller image treatment, or in conjunction with an air knife to further remove liquid.
