Abstract
Abstract A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. A replenishment pump calibration system is integrated into the processor so that no manual measurements or special tools are required to set replenishment solution rates.
