6.2.1. CLEAN ILLUMINATION SLIT AND FILM GUIDING OF THE FILM GATE
A dirty illumination slit causes vertical dark stripes in the picture signal.
Dirty film guides can lead to dirt deposits in the integration cylinder and may cause
scratches on the film.
For cleaning the illumination slit and the film guides the film gate has to be removed
and the integration cylinder has to be cleaned.
Remove the film gate, see section 6.4.1.
Clean the integration cylinder, see section 6.4.3.
Carefully clean the illumination slit, the film guides and all film-contacting surfaces
(use a cleaning cloth and isopropyl alcohol).
Also clean the ceramic film positioner of the optical block.
