The image isn’t square, but keystone-shaped.
■If the top or bottom of the image is broader, press the   or   
button on the projector until the image is square.
■If the projector is angled toward the screen from the left or right, 
the image will be broader on one side. Center the projector in 
front of the middle of the screen, facing the screen squarely. 
■Enable the Auto Keystone feature to automatically fix the shape. 
See page 108. 
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet, or an 
extension cable, the image quality may be reduced. Use a 
distribution amplifier for longer distances; you can purchase one 
from Epson (see page 13).
■Keep your computer and video cables away from the power cord 
as much as possible to prevent interference.
■The video signal may be split between the computer and the 
projector. If you notice a decline in the projected image quality 
when the image is displayed simultaneously on your notebook 
computer and the projector, turn off the notebook’s LCD display.
■Depending on the source you’re  projecting from, make sure the 
correct 
Input Signal or Video Signal is selected in the Signal 
menu (see page 107).
■If still images are jittery when  you are projecting from a video 
source, turn on the 
Progressive setting in the Signal menu (see 
page 107).
■Select Noise Reduction in the Signal menu, then try selecting 
NR1 or NR2. 
						

							
142Solving Problems
■Make sure your computer’s resolution setting is correct. Ideally, it 
should be 1280 
× 800 to match the projector’s native resolution 
for the PowerLite 826W+, or 1024 
× 768 for the PowerLite 
84+/85+/824+/825+. If this option isn’t available, select one of 
the other compatible video formats listed on page 157.
■If you are projecting from a co mputer, press the Auto button on 
the remote control. If that doesn’t work, you can adjust the 
Tracking and Sync settings in the Signal menu (see page 106).
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 120.
■Adjust the focus using the focus ring (see page 27).
■Make sure the lens is not fogged by condensation. You may need 
to wait before using the projector after moving it from a cold 
environment to a warm environment.
■Make sure the projector is facing  the screen squarely, to eliminate 
the need for keystone correction.
■Adjust the Sharpness setting on the Image menu (see page 105). 
When you change video settings,  you should be able to see the 
effect on the screen immediately. If you’re projecting from a 
computer, you may also need to ad just the tracking and sync as 
described in the next section. If  you don’t like the new settings, 
you can always select 
Reset to return to the factory default 
settings.
■Make sure the projector is within the recommended distance 
range (see page 16). 
						

							
Solving Problems143
You see vertical bands or the image still looks blurry after 
trying the solutions in the previous section.
■If you’re projecting from a computer and displaying an image that 
contains a lot of fine detail, you  may notice vertical bands or some 
of the characters may look heavy or blurred. Press the 
Auto 
button on the remote control to reset the projector’s tracking and 
sync settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu, as described 
on page 106.
1. Fill the screen with an image containing fine detail, such as  black text on a white background.
2. Adjust the 
Tracking to eliminate vertical bands. 
3. Adjust the 
Sync setting to increase the image sharpness. 
The image is too light or dark, or colors are incorrect.
■Press the Color Mode button to select a different color mode (see 
page 38). 
■Try adjusting the brightness and color settings in the Image menu 
(see page 104).
■Try changing the Power Consumption in the Settings menu 
(see page 108).
■Check your computer display settings to correct the color balance.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your notebook or computer 
monitor.

page 108).
■If you’re using a DVD player or 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 59.
■Make sure you are using a “no resistance” audio cable. 
						

							
Solving Problems145
■Make sure the audio cable is connected correctly and securely at 
both ends (see page 59). For computer audio, connect the cable to 
your computer’s  headphone jack or   audio out jack. If you 
need to disconnect or reconnect the cable, lower the volume first.
■Make sure the volume control on your computer is not turned all 
the way down or muted. In Windows, you may be able to use the 
volume control in your Windows system tray (lower right corner 
of the screen). On a Mac, you may be able to adjust the volume 
from your menu bar (top right corner of the screen) or via the 
volume control function keys. 
■If you are using a microphone connected to the projector’s Mic 
port, make sure the cable is connected correctly and securely and 
the 
Mic Input Level option on the Settings menu is adjusted 
correctly. See page 109 for more information. If you need to 
disconnect or reconnect the cable, lower the volume first.
■If you are using a condenser microphone, set the Plug-in Power 
setting to 
On in the Extended menu.
Solving Network Problems
You can’t display an image using Quick Wireless 
Connection. (PowerLite 85+/825+/826W+ only)
You may need to restart your computer to connect.
You can’t connect to the projector using EasyMP Network 
Projection. (PowerLite 85+/825+/826W+ only)
■Make sure the network cable is connected, as described on 
page 64.
■If you are using the optional wireless LAN module, make sure it is 
installed correctly in the projector, as shown on page 67.
■Restart your computer.
■Make sure your projector and comp uter are configured correctly; 
see page 71 (Ad Hoc mode) or page 78 (Access Point mode). 
						

							
146Solving Problems
■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 configuration 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 en abled your computer’s connection 
to the access point (see page 84) or that your wireless card or 
adapter is enabled and its SSID is set to match the projector’s 
SSID (see page 76). On a Mac, click the AirPort icon at the top of 
your Mac desktop to make sure AirPort is turned on and the 
projector’s SSID 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. 
						

							
Solving Problems147
■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 mo de 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 94.
■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 117.
■Make sure the network cable or Wireless 802.11a/b/g Module 
(PowerLite 85+/825+/826W+ only) is securely and correctly 
connected.
■Make sure power is being supplied to the projector. 
						

							
148Solving 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 32. 
■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 30° 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. To avoid interference, you 
can also turn off the projector’s front or back sensor with the 
Remote Receiver setting (see page 109), but this may limit 
where you can use the remote control.
■Make sure the projector’s sensors  have not been turned off with 
the 
Remote Receiver setting (see page 109).
■If any buttons are held for long er than 30 seconds, the remote 
enters sleep mode. Release any bu tton that is held to wake the 
remote. 
■If you’re using the remote control as a wireless mouse, make sure 
the 
USB Type B setting in the Extended menu is set to Wireless 
Mouse 
(see page 118).
