Best Tips For Projector Maintenance

Posted on August 2, 2012 by Nikhil P Naik

Setting up a maintenance schedule for your projector is very important. Environmental conditions and the lack of proper care can impact greatly on the lifecycle of the projector and the projector lamp.

Here we outline top ten tips to help with projector maintenance:

1) Space – Make sure there is plenty of space around the projector. It is important that the projector is kept ventilated and therefore it is advised that there is at least 2 feet of space around the projector to allow heat to dissipate from the unit. Projectors work on their ability to control the heat internally. Blocking the way the heat escapes can damage internal parts and reduce the lifecycle of the lamp.

2) Manual – Always take time to read the instruction manual or CD which came with the device. If you are unable to find this you may be able to download one online. Manufacturer’s guides often give you maintenance tips specific to your machine and can make you aware of any error notices your unit may display.

3) Temperature – Be very careful to monitor the temperature your machine is running at. Dust and dirt will affect the way the projector can cool itself and this will be different for every location the machine is used at. It is recommended the projector is kept away from direct sunlight and is not operated in temperatures below 40*F or above 90*F.

4) Mounting Your Projector – If you are mounting your projector on a ceiling make sure you use good quality mounting equipment. You do not want the machine falling off the mount, for the sake of saving money. Improper mounting of a projector can also risk the lives of those below it.

5) Filters – Filters are a vital part of a projector. Lamps act as the main source or light for a projector and dissipate quite a lot of heat to operator efficiently. In order to stop the unit over-heating, a fan or fans draw air in the unit and circulate this around the devices internal parts. Obviously, the air contains quite a bit of dirt and dust and this can clog the fan or cause the failure of the machine. A filter traps the dust and dirt allowing only clean to air to circulate. Read the manufacturer’s instructions as to when you should change the filter.

6) Projector Cabinet – Make sure once you have cleaned the projector filter that you also clean the projector cabinet. Use either a small vacuum cleaner or compressed air.

7) Lamps – Projector Lamps are a vital part of the unit. It is recommended always to use manufacturer approved lamps. Any other lamps will not only invalidate the projector warranty but may also be a health and safety risk. Projector bulbs go through vigorous testing to withstand excessive heats.

8) Stand By Mode – Never switch off the machine via the wall socket or pull the plug. Projectors often have a “cool down” option which is only activated once the projector has been powered down by either remote control or soft power button. This kicks in the fan to cool down the lamp and the machine effectively. Not allowing this cooling period to run can either diminish the life of your bulb or even crack it as the heat dissipates unevenly.

9) Projector Lens – Proper lens maintenance is vital to making sure the quality of the image being projected is maintained. Use a non-abrasive cleaner, such as a solution used for cleaning photographic lenses such as cameras. Apply the solution to a lint-free and dry cloth and then wipe the lens in a circular motion. Never apply the solution to the lens direct.

10) Powering On – Immediately after the machine has been set to stand-by it should be not be switched on for at least 30 minutes. This will allow the machine to cool effectively
