Epson Powerlite 826w+ Multimedia Projector Users Guide

							
Displaying and Adjusting the Image21
Also keep these considerations in mind: 
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and 
under the projector.
■Make sure the projector is within 9 feet (2.7 meters) (PowerLite 
84+/85+/825+/826W+) or 5 feet (1.5 meters) (PowerLite 824+) 
of a grounded electrical outlet or extension cord.
Ideally, you should place the projector directly in front of the center of 
the screen, facing it toward the screen squarely. The base of the lens 
should be at about the level of the bottom of the screen.

note
After positioning the

device to the lock port on the 
projector. You can purchase 
this from Epson; see 
page 13.

22Displaying and Adjusting the ImageIf you place the projector below screen level, you’ll have to tilt it up by 
extending the front adjustable foot. This causes the image to become 
“keystone” shaped, but you can correct the distortion by pressing the 
buttons on the projector. See page 28 for detailed information about 
correcting the image shape. 
For instructions on installing the projector in a permanent location, 
such as a theater or conference room, see page 151.
Turning the Projector On and Off
Make sure your projector and any computer or video equipment are 
connected as described on page
47. Turn on your connected 
equipment before starting the projector so it can automatically detect 
and display the image source. If you turn on the projector first, or 
have multiple pieces of connected equipment, you may have to select 
the image source manually (see page 25).

Turning On the Projector
Follow these steps to turn on the projector: 
1. Open the A/V Mute slide (lens cover).
2. Plug one end of the power cable into the projector, and the other end into an electrical outlet.
The  Ppower light turns orange.
note
You can set the projector to 
automatically turn off the 
lamp and enter “sleep mode” 
when it has not received any 
signals or the A/V Mute slide 
remains closed for a period 
of time. This conserves 
electricity, cools the 
projector, and extends the 
life of the lamp. To enable 
sleep mode, see page 117. 
Power light 
						

							
24Displaying and Adjusting the Image3. Press the 
Ppower button on the remote control or on top of the 
projector.
The projector beeps once and the  Ppower light flashes green as 
the projector warms up, then an image begins to appear. When 
the  Ppower light stops flashing and remains green, the projector 
is ready for use. 
4. If you are prompted to enter a password, see page 111.
Using the Direct Power On Function
The Direct Power On function enables faster setup. The projector will 
start up automatically when you plug it in; you won’t have to press the 
P power button. 
Follow these steps to enable Direct Power On:
1. Press the 
Menu button on the remote control and select the 
Extended menu. 
2. Choose 
Operation and press Enter.
3. Choose 
Direct Power On and press Enter.
4. Highlight 
On and press Enter.
5. Press 
Esc or Menu to exit. The setting will take effect the next 
time you plug in the projector.
warning
Never look into the lens 
when the lamp is on. This 
can damage your eyes, and is 
especially dangerous for 
children and pets.
note
If a power outage occurs 
when Direct Power On is 
enabled and the projector is 
plugged in, the projector will 
restart when the power is 
restored.

Shutting Down the Projector
This projector incorporates Instant Off technology. To turn the 
projector off, you can press its Ppower button as described below, or 
turn off a power switch that supplies power to the projector. You 
don’t have to wait for the projector to cool off first. 
1. To turn off the projector, press the  Ppower
 button on the remote 
control or projector.
You see a confirmation message. 
(If you don’t want to turn it off, press any other button.)
2. Press the  Ppower button again. When the  Ppower light stops 
flashing and you hear two beeps, unplug the power cord.
If you want to turn the projector on again, make sure the orange 
P power light is not flashing, then press the  Ppower button.
3. If you extended the adjustable front foot, press up on the foot  release lever to retract it.
4. Close the A/V Mute slide.
Selecting the Image Source
Selecting the image source lets you switch between images input from 
different pieces of connected equipment (such as a computer or DVD 
player). 
If you don’t see the image you want, press the 
Source Search button 
on the remote control or projector until you see the image you want to 
project.
note
Lamp life results will vary 
depending on mode selected, 
environmental conditions, 
and usage.
Turn off this product when 
not in use to prolong the life 
of the projector. 
note
To focus and adjust the 
image, see page 26. If a 
projected image fails to 
appear, see page 136 for 
help. 
						

							
26Displaying and Adjusting the ImageYou can also use the 
Computer, Video, and USB buttons on the 
remote control to switch between devices connected to the ports 
identified on each button, or select 
LAN to project through your 
network (the 
LAN button does not work with the PowerLite 84+ or 
824+). See page 33 for more information.
Adjusting the Image
Once you see your image, you need to make certain adjustments:    
■If the image is too high or too low, you can reposition it. See 
page 27.
■To focus or zoom your image, see page 27.
■If the image isn’t square, see page 28.
■If a computer image displays incorrectly, see page 30. 
■If you need to fine-tune the image and/or sound, see page 101. 
						

							
Displaying and Adjusting the Image27
Adjusting the Height of Your Image
If the image is too low on the screen, you can use the front adjustable 
foot to raise it. 
1. Stand behind the projector. Press the foot release lever up and lift the front of the projector.
2. Once the image is positioned where you want it, release the lever  to lock the foot in position.
3. If necessary, you can fine-tune the height or level of the image by  turning the projector’s adjustable rear feet. 
Raising the projector causes the image to distort or “keystone,” but 
you can correct the shape as described on page 28. 
Focusing and Zooming Your Image
Turn the focus ring on the projector to sharpen the image. 
Turn the zoom ring on the projector to reduce or enlarge the image. 
Focus Zoom  
						

							
28Displaying and Adjusting the ImageIf the image still isn’t large enough, you may need to move the 
projector farther away from the screen. You can also use the 
E-Zoom 
buttons on the remote control to zoom in on a portion of the image. 
See page 35 for instructions.
Adjusting the Image Shape
In most cases, you can maintain a square or rectangular image by 
placing the projector directly in front of the center of the screen with 
the base of the lens level with the bottom of the screen. 
Even if the projector is slightly tilted (within a range of 30° up or 
down), the projector has an automatic keystone correction function 
that detects and corrects vertical keystone distortion.
It takes about one second after projection starts for the image to be 
corrected. During this time, a vertical keystone correction gauge 
appears on the screen.
If your image is still distorted, you can correct it using the Keystone 
buttons on the projector’s control panel or the projector’s Setting 
menu.

Using Keystone Correction
To adjust your image when it is wider on the top or bottom, do the 
following:
■Press one of the two keystone correction buttons on the 
projector’s control panel, as shown below. Continue pressing the 
button until you are satisfied with the shape of the image.
■Or press the Menu button on the remote control or projector, 
select the 
Settings menu, and press Enter.
From the Settings menu, select 
Keystone and press Enter. Use 
the  pointer buttons on the remote control to adjust the 
keystone setting as needed. 
If the image quality declines (for example, lines or edges look 
jagged), reduce the sharpness setting. See page 105.
tip
You can display a test 
pattern to help align the 
image (see page 109).

Correcting Computer Images
If you’re connected to a computer and the image doesn’t look right, 
press the 
Auto button on the remote control or the Enter button on 
the projector. This automatically resets the projector’s tracking, sync, 
resolution, and position settings. 
If the 
Auto button doesn’t correct the problem, you may need to 
adjust the tracking or sync using the projector’s Signal menu. See 
page 106 for more information.
note
The Auto button works only 
with computer images 
projected through the VGA 
port.
