1. Regularly Replace Bulbs The lifespan of a projector bulb is limited, so it should be replaced regularly based on usage to avoid affecting projection quality due to bulb aging. 2. Regularly Check Circuits and Interfaces Regularly check the projector's circuits and interfaces for loose or damaged parts, and promptly repair or replace them to ensure the normal operation of the projector. 3. Keep Projection Image Clear Regularly calibrate the projection image to ensure a clear picture with bright colors. At the same time, keep the appropriate distance between the projection image and the screen to avoid blurry images caused by being too close or too far away. III. Professional Maintenance and Care If the above daily and in-depth maintenance still cannot meet your needs, or if you are not familiar with the maintenance of the projector, it is recommended to seek help from professionals. They can provide more professional cleaning, testing, and maintenance services to ensure that your office projector is always in the best condition.
