ABSTRACT:
A film cleaning apparatus cleans photographic film while the film is clamped at the print gate aperture of a photographic printer. When the film is clamped at the print gate, and before a print exposure is initiated, high velocity ionized air is directed onto both the top and bottom surfaces of the film to remove dust and other foreign materials from the film surfaces. When the exposure is commenced, the flow of ionized air is reduced to a low velocity which is sufficient to prevent dust from settling on the film surfaces during exposure.
