Calibrating
Calibration sets up the connection between your computer and the Easy
Interactive Pen. This simple process ensures that your computer can
accurately detect the position of the pen on the projection surface.
You need to calibrate before using the pen for the first time, or if you
change the resolution on your computer or connect a different computer.
You can use either pen for calibration.
Checking the Connection Status
Before you can calibrate, you need to make sure the Easy Interactive Driver
is activated on your computer.
a
Make sure the
pen icon appears on your screen, either in the
system tray on your taskbar in the lower right corner of your
screen (Windows) or in the Dock (Mac OS). It may take a minute
for the icon to appear after you turn on the computer and
projector.
If a red
appears on the icon, the computer and projector are not
^
connected correctly. Try removing and reconnecting the USB cable.
b
If you don't see the icon, do one of the following:
Windows
Select
or Start > All Programs or Programs > Epson Projector >
Easy Interactive Driver.
Mac OS
Open the Application folder, then select the Easy Interactive Driver
icon.
If you need more help,
When the Interactive Unit and projector are connected and the Easy
Interactive Driver icon is displayed, you're ready to calibrate. See the next
section for instructions.

Do not select Exit or Quit from the Easy Interactive Driver menu. If
you do, you will have to open the driver as described above the next
time you want to use the Easy Interactive Pen.
Performing Calibration
Two types of calibration are available:
• Normal, which is faster and appropriate for most situations (25
calibration points)
• Advanced, which is recommended when you are projecting very detailed
images and need higher accuracy (49 calibration points)
You may need to recalibrate if you change the projector's aspect ratio or if
you change the following settings: Auto Setup, Resolution, Tracking, Sync,
Position, Aspect, Keystone, or Zoom.
a
To start calibration, do one of the following:
Windows
Click the
pen icon in the system tray on your taskbar (lower
right corner of your screen), then select Calibrate (Normal) or
Calibrate (Advanced).
Mac OS
Click the
pen icon in the Dock, select Calibrate from the menu
bar, then select Calibrate (Normal) or Calibrate (Advanced).
