ABSTRACT:
An automatic anti-oxidation fluid replenisher system for processors of photosensitive material has an improved, digital electronic control system. The control system includes a digital binary counter which is counted down if use-related chemical replenishment is not occurring in the processor, and is counted up (generally at a different rate) if use-related chemical replenishment is occurring in the processor. When the counter reaches a predetermined value (e.g. zero), a detection circuit triggers anti-oxidation replenishment and resets the counter to its original value for further operation. A special circuit protects against counter roll-over should the counter reach its maximum capacity due to frequent chemical replenishment activity.
