Abstract

In current photoreceptor production, both small and large diameter substrates are coated sequentially in the same dip tanks. When small diameter substrates are coated, there is sufficient distance between the substrates and the walls of the tank that standing waves are formed as a result of vibration from the coating pumps. The standing waves cause periodic variations in the thickness of the coatings. It is proposed to use an insert that can be placed in the dip tank to reduce the total volume that must be filled with a coating
