FAQs – Epson EB‑685W Ultra Short Throw WXGA Projector

What do the status indicator lights mean?

The projector uses a combination of power (blue), lamp (orange), and temperature (orange) lights to signal issues. For example, blue off / lamp flashing orange indicates an overheating or lamp problem; blue flashing + temp orange off means excessive heat and a shut‑down. See user guide for full indicator patterns.

The image is blurry or out of focus—what should I do?

1. Adjust the manual focus ring.
2. Clean the projection window/lens.
3. If recently moved from a cold environment, allow the projector to warm up to room temperature to avoid condensation.

The image is too dark, washed out or colors seem off—help!

• Ensure cables are securely connected, preferably using HDMI.
• Switch from Eco to Normal brightness mode to improve image quality.
• Replace the lamp if image dimmed over time.

There’s no sound—why?

• Confirm audio source/device volume and switch to PCM output if using HDMI.
• Check projector volume and verify correct audio input selected.
• For USB Display mode, enable “Output audio from the projector” in the Epson USB Display software.
• On Mac HDMI, some models require a separate audio cable.

The projector buttons aren’t responding—how do I fix this?

Button lock can be activated accidentally. To unlock, press and hold the Enter button for ~7 seconds until the unlock message appears. Or from the remote: go to Settings → Lock Setting → Control Panel Lock → Off.

How to change the projector’s network name?

1. Press Menu, go to Network → Network Configuration → Basic.
2. Select Projector Name, enter up to 16 alphanumeric characters, and confirm.
3. Exit menu—your custom network name is set.

Can I update the firmware myself?

Yes, firmware updates are supported via USB. You can use a USB-A flash drive (plugged into the projector) or connect via USB-B to a computer.

How do I connect devices (PC, Mac, DVD, document camera)?

The EB‑685W includes HDMI, VGA, composite, USB-A/B ports.

• For HDMI, simply connect video/audio cable.
• For USB-B, install Epson USB Display software to stream video/audio from a connected PC.
