Abstract
Abstract Described herein is a high capacity, low volume processor for processing photographic material in web form. The processor is self-threading and is capable of being linked directly to a high-speed printer. The processor can be replenished by direct replenishment of concentrates without external chemical mixing. "Fluid drive" is preferably used to provide both transport of the web through the processing tanks and to provide agitation at the surface of the web.
