Operating a projector might put many non IT/ AV users off with all the new features and functions, let alone maintaining one. But it is really not that difficult in doing a simple routine cleaning to help prolong the efficiency of the projector.
As long as the projector is within reaching distance, you might want to adopt the following steps in maintaining your projector:
- Allow the projector to cool down before cleaning
– Wait for at least 2 hrs after use prior to cleaning
– As you might shake the projector during cleaning, internal optical engines and lamps which is still hot might easily results in cracks or damages
- Remove Air Filter
– Most projectors have an Air Filter to prevent dust from entering the optical engine
– These filters are usually easily accessible from the side of the projector to allow easy maintenance
– Do note that a projector without an Air Filter does not equals to no need for cleaning
- Vacuum clean filter and surrounding of the whole projector
– Use a vacuum cleaner to clean the air filter
– Some Air Filters are sponge like (enable for washing) but vacuum clean will suffice
– Vacuum the whole projector for any dust/ dirt resting on it
– A damp cloth can be used to clean the casing of the projector but make sure it does not drip water into the projector
- Clean the lens with a soft damp cloth
– Use cloth that does not drop fine furs during cleaning
– Use a clean dry cloth to wipe the lens dry after cleaning with the damp cloth
– Routine checks on the lamp hours to prepare for lamp replacement when current lamp is running dim
– Project some test pattern to ensure focus and sharpness, usually easily adjusted from the lens/ menu
– Ensure that all connected ports are secure
With the 5 easy steps, everyone should be able to DIY a projector maintenance.
Apart from sharing the pointers on projector maintenance, do you know that projector maintenance actually starts from the moment you choose your projector?
Below are the few features that you can look out for in a projector that will help you in ease of maintaining it for the years to come:
– Easily access Air Filter and Lamp design even after ceiling mounted installation, which allows the user to change filter and lamp without having to dismount the projector
– Enhanced Air Filter design to reduce the frequency of cleaning
– If intention to operate in poor air condition environment (i.e. smoking areas, dusty rooms), look for projectors with internally sealed optical engines (cost more but goes a long way in protecting the projector)
– Installation away from direct air-con to avoid condensation inside projector during cooling down
– Longer lasting lamps to reduce the frequency of changing lamps and also translates to lower operating cost
The pointers above serve to help users plan ahead when making purchase for a new projector.
