A dusty projector filter or warning light can signal maintenance. Epson's instruction for certain removable filters is to remove the filter, gently tap out loose dust, and vacuum its designated front face. Filter access and maintenance differ by model; the cover photo shows an Epson EB-U04 rather than a filter-cleaning demonstration.

0 / 6 done

1. Check for filter-cleaning messages or an orange indicator, then locate the filter and maintenance instructions for your exact projector model.
2. Shut down normally, wait for the prescribed shutdown signal, unplug the power cord, and allow the projector to cool before access.
3. Open the correct filter cover and carefully remove the serviceable filter as shown in the model manual. Do not take risks reaching a ceiling-mounted projector.
4. Gently tap each side of the filter about four or five times and carefully vacuum the front face specified in the guide (the side with the tabs).
5. For the filter covered by this Epson guide, never rinse it or use water, detergent, solvent or canned compressed air. Excess force can crack the filter.
6. Replace a damaged or persistently clogged filter with the correct part; reinstall the filter and cover fully and check the projector's status.
