One of the main causes of projector issues is dust. Dust accumulation wreaks havoc by reducing the projector’s ability to dissipate heat, which can cause color fading and unexpected system failure. And that’s just the beginning. When dust collects on the DLP projectors’ color wheel, the projector cannot be turned on. These problems not only cost valuable class time to fix, but also decrease students’ attention and ability to learn. It’s estimated that educators spend over 100 minutes of class time every week troubleshooting problems with equipment in the classroom, including projectors. It’s also reported at 65 percent of students are visual learners, which means without the aid of projection technology, students may not fully grasp the concept. In today’s fast-paced education environment, it’s essential that students have every opportunity in class to learn. This is why projectors should be maintained regularly, including cleaning projector filters and casings.
