Latest Patents

Higginson holds a patent for a self-cleaning electrostatic color printer. This invention features a single toning shoe that successively and sequentially applies color liquid developers to a color latent image overlay on a sheet positioned against a rotating drum. The electrostatic head scans the sheet in a helical pattern, forming the latent image. Following this, the toning shoe assembly applies one of the color developers to the sheet. A drain selector foot pivots beneath the toning shoe, allowing for the recycling of used developer back to the appropriate supply tank. After the scanning process, the toning shoe is rinsed with a solvent at a cleaning station. The design includes pressure-responsive reed valves that select sequential color developers, ensuring the entire image is toned through repeated passes.
