Product Information
Full details
The Epson EB-685Wi is a high-performance, ultra-short-throw interactive projector designed primarily for educators and corporate presenters who need to transform flat surfaces into collaborative workspaces. Its primary strength lies in its dual-pen interactivity and 3LCD technology, which ensures vibrant, high-quality images even in well-lit rooms. A notable caveat for users is the short-throw design, which requires careful alignment with the projection surface to ensure optimal image geometry and touch-sensor accuracy.

FAQs
Can I use the EB-685Wi without an interactive whiteboard?
Yes, it can project onto any flat, matte-finish wall, though a dedicated whiteboard or screen provides the best interactive surface.
How do I switch the lamp to Eco mode?
Navigate to the 'Image' menu in the projector settings and select 'Lamp Mode' to toggle between Normal and Eco settings.
Does this projector include a wall mount?
No, this specific model (V11H741541) is the 'no mount' variant; a compatible ultra-short-throw mount must be purchased separately.
Can two people write at the same time?
Yes, the EB-685Wi supports dual-pen interactivity for simultaneous multi-user collaboration.
What is the recommended cleaning interval for the air filter?
It is recommended to check and clean the air filter every three months, or more frequently if used in a dusty environment.
Can I connect this projector to a Mac?
Yes, the projector supports standard HDMI connectivity which is compatible with Mac devices using the appropriate video adapter.
Troubleshooting
Interactive pens are not responding to the projected surface
Ensure the pens have fresh batteries and recalibrate the interactive functionality using the projector's menu settings.
The projected image appears distorted or uneven
Check the mounting alignment and use the keystone correction tools to square the image; ensure the projection surface is completely flat.
Wireless connection via iProjection is intermittent
Check your local network signal strength and ensure that your device and the projector are on the same Wi-Fi subnet.

Setup, Compatibility & Care
To begin using the EB-685Wi, ensure the unit is securely mounted to a wall or stand that is perfectly level. Since this is an interactive projector, the calibration process is vital; use the built-in calibration tool to align the touch sensors with your projected image.
For connectivity, the projector supports HDMI and various standard inputs. For wireless casting, you can utilize the Epson iProjection App on your mobile device or laptop. To maintain the device, regularly clean the intake air filters to prevent overheating, which protects the lamp and internal components. Avoid touching the lens with bare hands and always allow the projector to complete its cooling cycle after shutting it down before disconnecting the power.
