The pen doesn’t work.
■Make sure nothing is blocking the signal between the pen and the 
interactive pen receiver on the projector (see page 14). 
■Make sure the cable cover is in place to keep cables from 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.
■If you are projecting through a wired or wireless network, make 
sure the 
USB Type B option is set to Wireless Mouse in the 
Extended menu (see page 78).
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projection surface and the pen receiver are not in direct 
sunlight or other sources of bright lighting.
■Make sure the USB cable is securely connected to the projector 
and computer. Try disconnecting and reconnecting the cable to 
your computer. 
The pen is hard to use.
For easier operation, hold the pen at an angle to the projection 
surface.
The pen position is not accurate.
■If you use the E-Zoom + button on the remote control to enlarge 
the image, the pen position will not be accurate. When you return 
to the original size, the pen position should be correct.

■Make sure the cable cover is in place to keep cables from blocking 
the signal. 
						

							136Solving Problems
You’re having trouble calibrating.
■If the flashing circles don’t appear, make sure the VGA cable and 
USB cable are securely connected to the computer. Try restarting 
the Easy Interactive Driver, as described on page 134.
■If the circles don’t stop flashing and turn black (or they stop 
flashing and turn black automatically), dim or turn off any bright 
lights near the projection surface.
Solving Password Problems
If you cannot enter or remember a password, try the following 
solutions:
■You may have turned on password protection without first setting 
a password. Try entering 
0000 using the remote control.
■If you have entered an incorrect password too many times and see 
a message displaying a request code, write down the code and 
contact Epson as described on page 140.
Solving Network Problems
You can’t display an image using Quick Wireless 
Connection.
You may need to restart your computer to connect.
You can’t connect to the projector using EasyMP Network 
Projection.
■Make sure the network cable is connected, as described on 
page 86.
■If you are using the optional wireless LAN module, make sure it is 
installed correctly in the projector, as shown on page 89.
■Restart your computer. 
						

							Solving Problems137
■Make sure your projector and computer are configured correctly; 
see page 94 (configuring the projector) or page 96 (configuring 
the computer).
■If you are using the optional wireless LAN module, make sure 
that you have sufficient wireless signal strength (above 50 
percent). On a Mac, check the AirPort icon on the Mac menu 
bar. In Windows, see the documentation for your computer’s 
wireless card or adapter for details.
■Make sure you aren’t projecting one of the EasyMP Network 
Projection screens. (You should see a message that the projector is 
ready to connect.) If you have to exit a configuration screen, 
restart EasyMP Network Projection.
■If the projector is configured for Access Point mode and you’re 
using DHCP, allow time for your projector to appear. It takes the 
server a little while to pick up the IP address.
■If you’ve changed any settings for your projector or network, or 
restarted your computer, allow a minute or two for the 
connection to appear. If you’re using AirPort, try turning AirPort 
off and then on again.
■Make sure that you’re trying to connect to the right network. In 
Windows, verify that you’ve enabled your computer’s connection 
to the access point or that your wireless card or adapter is enabled 
and connected to the same SSID as the projector. On a Mac, click 
the AirPort icon at the top of your Mac desktop to make sure 
AirPort is turned on and the right network is selected.
■If you have an access point or AirPort base station and you’re not 
using DHCP, check your projector’s IP address on the Access 
Point mode advanced settings screen. The first three segments of 
the IP address should be identical to the first three segments of the 
IP address of your access point or base station. The last segment of 
the projector’s IP address should be close, but not identical, to the 
last segment of the IP address of the access point or base station.  
						

							138Solving Problems
■If you’re not using DHCP, check your projector’s Gateway 
address on the projector’s Access Point mode advanced settings 
screen. It should be identical to the IP address for your access 
point or AirPort base station.
■If you’re using a projector keyword, it changes each time you turn 
the projector off and then on again. Check the projector’s 
keyword on the LAN standby screen and enter it at the prompt.
■If you’re using AirPort, check the configuration of your network. 
Start the AirPort Admin utility, select your base station, click 
Configure and click Show All Settings. Click the Network 
tab. If you set up your projector to connect in DHCP mode, turn 
on 
Distribute IP Addresses and Share a Single IP Address. 
■If you’re using AirPort and DHCP is turned off on your 
projector’s Access Point mode advanced settings screen, make sure 
Distribute IP Addresses is off. 
■If you’re using Access Point mode and you’re connecting to the 
wrong network, you may be experiencing signal interference from 
another network. Try resetting your access point or base station, 
then restart EasyMP Network Projection.
■If you’re using AirPort, the projector’s SSID should match the 
AirPort network name, not the name of the AirPort base station. 
To check the network name, start the AirPort Admin utility, 
select your base station, and click 
Configure. Then click Show 
All Settings
. The network name appears on the AirPort tab.
■If you’re prompted for a password when you connect, enter the 
WEP encryption key (if you’re using WEP encryption).
You are not receiving mail when a projector problem occurs.
■Make sure the Mail settings are correct in the Network menu. For 
details, see page 101.
■To receive mail notification when the projector is in standby 
mode, you need to set 
Standby Mode to Communication On 
in the Extended menu. See page 78. 
						

							Solving Problems139
Solving Problems With the Remote 
Control
The projector doesn’t respond to remote control commands.
■Point the remote control towards the projector’s receiver. Make 
sure you are within 19.7 feet (6 meters) of the projector and 
within a 30° horizontal angle and a 15° vertical angle from the 
projector’s front or back receiver.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 119. 
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in direct sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater. 
■If you can’t adjust the room lighting, you can turn off one of the 
remote receivers by using the Settings menu. Make sure the 
receivers are not both turned off (see page 76).
■Check to see if a button on the remote control is stuck down, 
causing it to enter sleep mode. Release the button to wake the 
remote.
■If you want to use the remote control as a wireless mouse (or to 
move through presentation slides), make sure 
USB Type B in the 
Extended menu is set to Wireless Mouse (see page 78). Also, 
make sure you have connected the USB cable.
