If the pens do not work, try the following
solutions:
Make sure
nothing is blocking the signal between the pen and the interactive
module on the projector.
Try
holding the pen at a different angle so that your hand is not
blocking the signal.
Make sure
the pen batteries have enough power. If the light on the pen
doesn't turn green when you press the button, you need to replace
the batteries.
Make sure
Easy Interactive Driver is installed and running on your computer.
You should see the icon in
your taskbar (Windows) or in the Dock (Mac OS X).
If you don't see the icon, do
one of the following to start Easy Interactive Driver:
Windows: Select or
Start > All Programs or
Programs > EPSON Projector
> Easy Interactive Driver.
Mac OS X: Open the Applications folder, then select the
Easy Interactive Driver icon.
If the icon has
a red X above it (),
make sure the USB cable is securely connected to your computer and
the interactive module. If necessary, try disconnecting and
reconnecting the USB cable to your computer.
Dim the
room lights and turn off any fluorescent lights. Make sure the
projection surface and interactive module are not in direct
sunlight or other sources of bright lighting.
Make sure
the receiver window on the interactive module is clean and free
from dust.
Make sure
there is no interference from infrared devices such as infrared
remote controls, infrared microphones, and infrared mice.
Make sure
the location is free from electromagnetic interference from nearby
equipment (such as electric motors or transformers).
Make sure
you have calibrated the system. Try recalibrating.
