A method of tracking backflow assemblies is provided. The intermediate members are selectively locked to or unlocked from the body of the image forming apparatus. Generally, the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate, thus creating engineered particles from the optically functional material. These characteristics are used to form a feedforward signal adapted to cancel the noise at the desired position. The releasable retention component resides at least partially within the liquid manifold when operatively holding the conduit within the conduit-receiving opening. Then, the blur correcting means extracts high frequency components from the reduced image, and performs blur correction by emphasizing and adding the extracted high frequency components to the reduced image.
