6.3 Inspect the Lamp
Always disconnect the cinema projector from AC power and wear authorized
protective safety gear.
• Check the contact surfaces of the anode (positive) and the cathode (negative) connections for cleanliness.
• Clean electrical contact surfaces regularly to prevent contact resistance from scorching connectors. Use an
approved contact cleaner.
• Verify that all electrical and lamp connections are secure.
6.4 Inspect and Clean Optics
Unnecessary cleaning of optics can increase the risk of degrading delicate coatings and surfaces. If you are not
a qualified service technician, you can only inspect and clean the lens and lamp reflector. Do not perform
maintenance on other optical components. Check these components periodically in a clean, dust-free
environment using a high-intensity light source or flashlight. Clean them only when dust, dirt, oil, fingerprints
or other marks are obvious. Never touch an optical surface with your bare hands. Always wear latex lab gloves.
These are the recommend tools for removing dust or grease:
• Soft camel-hair brush
• Dust-free blower - filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue, such as Melles Griot Kodak tissues (18LAB020), Opto-Wipes (18LAB022), Kim
Wipes or equivalent.
• For the lens only - lens cleaning solution such as Melles Griot Optics Cleaning Fluid 18LAB011 or equiva-
lent
• For the reflector only - Methanol.
• Cotton swabs with wooden stems.
• Lens cleaning cloth or microfiber such as Melles Griot 18LAB024 or equivalent.
6.4.1 Clean the Lens
A small amount of dust or dirt on the lens has minimal effect on image quality-to avoid the risk of scratching
the lens, clean the lens only if absolutely required.
Remove Dust
1. Brush most of the dust off with a camelhair brush or use a dust-free blower.
2. Fold a microfiber cloth and wipe the remaining dust particles off the lens with the smooth portion of the
cloth that has no folds or creases. Do not apply pressure with your fingers. Instead, use the tension in the
folded cloth to remove the dust.
3. If significant dust remains on the lens surface, dampen a clean microfiber cloth with lens cleaning solution
and wipe gently until clean.
