Coating of Photoconductor Drum using a Hydraulic Ring Head

Disclosed is a device and process for coating a seamless photoconductor drum, such as those used in a laser printer.

The process uses a ring-shaped coating head. A drum core is passed through the ring coating head with an annular gap of known thickness. Ink under pressure is supplied to the gap. Hydraulic pressure exerted by the ink centers the drum. The thin coating is formed when the drum core moves out of the sleeve. The gap thickness, ink viscosity and the speed of motion determine the desired thickness. Sequential processes with on-line drying can be used for coating a multi-layered photoconductor drum.
