How to maintain the Epson PowerLite 1780W

The Epson PowerLite 1780w is a compact, portable projector that can be carried around with you and taken from meeting to meeting. It’s a tough little unit that can take the bumps and tumbles that come with being carried around in a bag.

Despite its rugged design, its still a projector you want to look after to make sure you get the most out of. The last thing you want is it over heating after being taken out of your bag or for the picture quality to drop.

Here’s your comprehensive guide to maintaining your Epson PowerLite 1780w:

How should I transport the projector?

Many parts of the projector are made out of delicate parts. Any harsh impact can cause misalignment inside the projector that can impede the display quality:

      • Keep the lens covered in transport with the lens protector.
      • Remove any equipment connected to the projector.
      • Use the case when transporting the projector, even by hand.
      • When transporting the projector a long distance or as checked luggage, place it in a carrying case. Then pack the case in a firm box with cushioning around it and mark the box “Fragile.”
      • When shipping the projector for repairs, place it in its original packing materials, if possible, or use equivalent materials with cushioning around the projector. Mark the box “Fragile.”

When and how should I clean or replace the air filter?

The projector will notify you when the filter needs cleaning. However, you should clean the filter whenever you notice a build up of dust inside the projector.

      1. Turn off the projector and unplug the power cord.
      2. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).

        Note: You can remove the air filter so you can clean both sides of it. Do not rinse the air filter in water, or use any detergent or solvent to clean it.

        Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector’s optics or other sensitive areas.

      3. Replace the air filter when it becomes full of dust that can’t be removed or when it gets damaged.

Replacing the Air Filter

You need to replace the air filter in the following situations:

      • After cleaning the air filter, you still see a message saying the air filter needs to be cleaned or replaced.
      • The air filter is torn or damaged

You can replace the air filter while the projector is mounted to the ceiling, if necessary.

    1. Turn off the projector and unplug the power cord.
    2. Grasp the tab at the center of the air filter and pull it out of the projector.

      Note: Air filters contain polycarbonate, ABS resin, and polyurethane foam. Dispose of used air filters according to local regulations.
    3. Place the new air filter in the projector as shown and push gently until it clicks into place.

How should I clean the lens?

Clean the projector’s lens periodically to remove dust and smudges on the surface.

    • Gently wipe the lens with lens-cleaning paper.
    • To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the lens. Do not spray any liquid directly on the lens.Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector lamp may cause a fire.

      Caution: Do not use glass cleaner or any harsh materials to clean the lens. Do not subject the lens to any impacts; you may damage it. Do not use canned air, or the gases may leave a residue. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.

How do I replace the lamp?

Before you replace the lamp, let the projector cool down for at least one hour so the lamp will not be hot.

Warning: Let the lamp fully cool before replacing it to avoid injury.

You can replace the lamp while the projector is mounted to the ceiling, if necessary.

      1. Turn off the projector and unplug the power cord.
      2. Allow the projector lamp to cool down for at least one hour.
      3. Use the screwdriver included with the replacement lamp to loosen the screw securing the lamp cover.

    • Press the Menu button.
    • Select the Reset menu and press Enter.
