Cleaning
Keep your camera in top condition by following these suggestions for
periodic cleaning. See the precautions on page 4 for other important
information.
1. Cleaning the lens surface—
Blow off dust with a blower brush and gently wipe the lens surface with
a piece of lens cleaning paper moistened with lens cleaner. Clean in a
spiral motion from the center outwards.
2. Cleaning mirror and focusing screen—
Use a blower brush reserved for this purpose only. If more clean­
ing is necessary do not attempt to do it yourself. Take the camera to
an authorized Canon service facility.
3. Cleaning the film chamber—
Use a blower brush to remove accumulated film dust particles that
might scratch the film. Be careful not to touch the shutter curtain.
4. Cleaning the film pressure plate and film guide rails—
Lightly wipe the surface with a piece of lens cleaning paper moistened
with lens cleaning fluid. Be careful not to touch the shutter curtain.
• Use of aerosol spray dust removers is not recommended.
