Dust remover for film in printer - has cleaning brush and uses moist filtered airstream

摘要

The dust remover from a film used in a photographic printer has rotating brushes to remove the dust and a moist airstream to ensure that further dust is not attracted prior to printing. The moist air is filtered and is applied in two stages, with the brushes rotated between the stages. The printer produces high quality prints. The film is held on a metal plate linked to a control bias, while a suction system removes the loosened dust.
