■Try adjusting the Brightness and Contrast settings on the Image 
menu.
■Check your computer display settings to correct the color balance.
■The projector’s lamp may need to be replaced. See page 146 for 
instructions.
There is no sound, or the sound is not loud enough.
■Press the   button on the projector or remote control to increase 
the volume.
■Make sure A/V Mute is not enabled. (The A/V Mute button may 
have been pressed.) 
■Try adjusting the Volume setting in the Setting menu (see 
page 114).
■If you’re using a VCR or other video source, make sure the 
volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described on page 47.
■If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. If you’re using the audio cable, make sure it is securely 
connected to both the projector and your computer’s 
headphone jack or   audio out jack.
■Make sure the Windows volume controls on your computer are 
not turned all the way down or set to Mute. You may be able to 
check this by clicking the volume control in your Windows 
system tray (lower right corner of the screen).
■If you are using external speakers, you need to set the EasyMP 
Audio Out
 option to External. When this setting is enabled, you 
can’t use the buttons on the projector or remote to control the 
volume. See page 48 or page 114 for more information. 
						

							162Solving Problems
Solving Network Problems 
You don’t see your projector in the EMP Monitor window.
■Make sure that you’ve connected the projector to the network and 
configured it correctly; see page 52. Also, make sure you’ve 
registered the projector with EMP Monitor; see page 122.
■Make sure that Standby Mode in the projector’s Extended menu 
is set to 
Network ON.
■If the computer you are using is running Windows XP or 2000, 
you must be logged in as the Administrator.
■Try restarting your computer.
You can’t connect to the projector using NS Connection.
■Make sure you’ve installed the Epson 802.11g card correctly in 
the projector; see page 50. If you have to reinstall the card, restart 
NS Connection or the program will not be able to detect the 
projector.
■Restart your computer.
■Make sure your projector and computer are configured correctly; 
see page 52 (Ad Hoc mode) or page 59 (Access Point mode).
■Make sure that you have sufficient wireless signal strength (above 
50 percent). On a Macintosh, check the AirPort icon on the 
Macintosh 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 configuration 
screens. (You should see a message that the projector is ready to 
connect.) If you have to exit a configuration screen, restart 
NS Connection.
■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. 
						

							Solving Problems163
■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 (see page 66) or that your wireless card or 
adapter is enabled and its SSID is set to match the projector’s 
ESSID (see page 57). On a Macintosh, click the AirPort icon at 
the top of your Macintosh desktop to make sure AirPort is turned 
on and the projector’s ESSID or your AirPort 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. 
■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, or remove and reinsert the 
802.11g wireless card. Check the projector’s keyword on the 
EasyMP Network 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.  
						

							164Solving Problems
■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 NS Connection.
■If you’re using AirPort, the projector’s ESSID 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).
■Try connecting using IP Connect Mode; see page 80.
Solving EasyMP Problems 
An image displayed with EasyMP appears distorted.
Because of their resolution, some JPEG images cannot be displayed 
correctly. Some JPEG files from digital cameras cannot be previewed. 
Files with a high compression ratio may appear blurry.
In EMP SlideMaker 2, PowerPoint files don’t appear in the 
file window.
EMP SlideMaker 2 does not support PowerPoint 95 or 97. Files 
created in these versions of PowerPoint must be opened and resaved in 
PowerPoint 2000 or later.
In EMP SlideMaker 2, your PowerPoint files don’t display 
thumbnails and can’t be pasted into scenarios.
Make sure the MS Office JPEG converter has been installed. Run the 
Office installer, display the 
Converters and Filters option, and 
install the JPEG filter. Also, make sure PowerPoint is installed on the 
computer you’re using to build the scenario. 
						

							Solving Problems165
You can’t edit scenario files in EMP SlideMaker after they 
have been transferred to the memory card.
You can only edit scenarios before they are transferred. Open the 
scenario files saved on your hard drive, make any changes, then 
transfer the scenario to your memory card.
You can’t transfer your slideshow to the memory card 
because you aren’t able to see the card’s drive letter.
You must insert the memory card in your computer’s PCMCIA slot 
before you select 
Send Scenario from the Scenario Option(s) menu. 
If this happens, close and restart EMP SlideMaker 2. Make sure your 
card is inserted before you select 
Send Scenario.
You can’t play your movies on the projector.
■The projector only supports MPEG2 files. It does not support 
MPEG1 files. 
■Movie files included in a PowerPoint presentation can’t be played 
back in a scenario.
EasyMP is unable to see the image files on your camera or 
external drive.
Make sure your camera or drive shows up on your desktop as a drive 
letter when you connect it to your computer. If it does, it is probably a 
USB-mounted device and will work with your projector. The 
projector does not support TWAIN-compliant digital cameras. 
						

							166Solving Problems
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 30. 
■Make sure you are within about 20 feet (6 meters) of the projector 
and within range of the projector’s front or back sensor 
(approximately 30° to the left or right and 15° above or below).
■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.
