Important Safety Information

WARNING: Never look into the projector lens when the lamp is turned on; the bright light can damage your eyes. Never let children look into the lens when it is on. Never open any cover on the projector, except the lamp and filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as specifically explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing to qualified service personnel.

WARNING: The projector and its accessories come packaged in plastic bags. Keep plastic bags away from small children to avoid any risk of suffocation.

Caution: When you replace the lamp, never touch the new lamp with your bare hands; the invisible residue left by the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.

Displaying and Adjusting the Image

Whether you’re presenting from a computer or video equipment,

you need to follow some basic steps to display your image on the screen.

Follow the guidelines in this chapter for:

■ Positioning the projector

■ Turning the projector on and off

■ Selecting the image source

■ Troubleshooting display problems

■ Adjusting the image

note

You can mount the projector on the ceiling, or place it behind a translucent screen for rear projection. See page 89 for details.

Positioning the Projector

If the projector isn’t already installed in the room you’re using, you’ll probably want to place it on a table in front of the screen. This lets you stand in the front of the room, face the audience, and remain close enough to the equipment to be able to control it. Try to leave as much space as possible between the projector and the screen to get a good-size image.

Use the figures below to help you determine placement. (The image shown below is projected at a 4:3 aspect ratio, but the PowerLite 1730W is capable of displaying images as wide as 16:10.) Image size increases with distance, but can vary depending on how you position the zoom ring and whether you’ve adjusted the image with other settings.

TBD

PowerLite 1720 PowerLite 1730W

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. Do not set the projector on top of anything that could block the vents.

■ Make sure the projector is within 10 feet of a grounded electrical

outlet or extension cord.

14 Displaying and Adjusting the Image

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.

Projector

Screen

If 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 23 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 89.

note

After positioning the projector, you may want to connect a Kensington MicroSaver device to the lock port on the projector. You can purchase this from Epson; see page 12.

anti-theft

Turning the Projector On and Off

Make sure your projector and any computer or video equipment are connected as described on page 39. 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 18).

Displaying and Adjusting the Image 15

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 64.

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.

Displaying and Adjusting the Image 21

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

below.

■ To focus or zoom your image, see page 23.

■ If the image isn’t square, see page 23.

■ If a computer image displays incorrectly, see page 25.

■ If you need to fine-tune the image and/or sound, see page 49.

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.

Projector rear foot

Raising the projector causes the image to distort or “keystone,” but you can correct the shape as described on page 23.

22 Displaying and Adjusting the Image

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

If 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 31 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.

Corrected imageProjector tilted up Projector tilted down

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.

warning

Before you clean any part of the projector, turn it off and unplug the power cord. Never open any cover on the projector, except the lamp cover. Dangerous electrical voltages in the projector can injure you severely. Do not try to service this product yourself, except as specifically explained in this User’s Guide. Refer all other servicing to qualified service personnel.

Maintaining the Projector

Your projector needs little maintenance. All you have to do is keep

the lens clean. You may also need to clean the air filter and vent. A clogged air filter or vent can block ventilation needed to cool the projector.

The only parts you should replace are the lamp and air filter. If any other part needs replacing, contact your dealer or a qualified servicer.

This chapter covers the following:

■ Cleaning the lens

■ Cleaning the projector case

■ Cleaning the air filter and vent

■ Replacing the lamp and air filter

■ Transporting the projector

caution

Do not use wax, alcohol, benzene, paint thinner, or other chemical detergents. These can damage the case.

Never spray a liquid of any kind directly on the

rojector or its lens. Always

apply it to a cloth first.

Cleaning the Lens

Clean the lens whenever you notice dirt or dust on the surface.

To remove dirt or smears on the lens, use lens-cleaning tissue. If necessary, moisten a soft cloth with lens cleaner and gently wipe the lens.

Cleaning the Projector Case

Before you clean the case, turn off the projector and unplug the power cord.

■ To remove dirt or dust, wipe the case with a soft, dry, lint-free

cloth.

■ To remove stubborn dirt or stains, moisten a soft cloth with water

and a neutral detergent. Then wipe the case.

68 Maintaining the Projector

Cleaning the Air Filter and Vent

Your projector includes an air filter to ensure the best performance. If dust collects on the air filter (on the side of the projector) or vent (on the front of the projector), clean them as described below. Dust clogs prevent proper ventilation and can cause overheating and damage the projector.

Follow these steps:

1. Turn off the projector. Wait for the P

flashing, then unplug the power cord.

2. To clean the intake vent and filter, use a small vacuum cleaner

designed for computers and other office equipment. If you don’t have one, gently clean the vent with a soft brush (such as an artist’s paintbrush).

You can remove the air filter to clean both sides.

Projector Installation

This appendix provides guidelines on installing the projector in a

permanent location, such as a theater or conference room.

The projector can be installed for four different viewing setups: front projection, ceiling projection, rear projection onto a semi-transparent screen, or rear/ceiling projection, as shown:

Front projection Rear projection

Rear/ceiling projectionCeiling projection

To project from overhead, you’ll need the optional ceiling mounting hardware; see page 12 for ordering information. You’ll also need to select

Front/Ceiling or Rear/Ceiling as the Projection option in the

projector’s Extended menu to flip the image upside-down. To project from the rear, onto a semi-transparent screen, select

Rear/Ceiling (see page 63).

Rear or

If you’re mounting the projector on the ceiling and you place it above screen level, you’ll have to tilt the projector down to position the image on the screen. This causes the image to lose its square shape. You can correct the distortion using the

Keystone function in the

projector’s menu system (see page 56).

If you place the projector so that the base of the lens is level with the bottom of the screen, the image should be square and you won’t have to adjust it. If you place the lens lower than the bottom of the screen, you’ll have to tilt the projector upward if you want to fill the whole screen with the image.

Compatible Video Formats

The projector supports NTSC, PAL, and SECAM international video standards, as well as the monitor display formats listed below.

To project images output from a computer, the computer’s video card must be set at a refresh rate (vertical frequency) that’s compatible with the projector. Some images are automatically resized using Epson’s SizeWise™ technology to display in the projector’s “native” format (XGA or WXGA). The frequencies of some computers may not allow images to display correctly; see your computer’s documentation for details.

Notices

This appendix includes safety instructions and other important information

about your PowerLite projector.

Important Safety Instructions

Follow these safety instructions when setting up and using the projector:

■ Do not look into the lens when the projector is on. The bright light can

damage your eyes.

■ Do not place the projector on an unstable cart, stand, or table.

■ Do not operate the projector on its side, or while tilted to one side.

Do not tilt the projector more than 30° forward or back.

■ If the projector is mounted on a ceiling, it should be installed by

qualified technicians using mounting hardware designed for use with this projector.

■ If you use a ceiling mount and apply adhesives to the mount to prevent

the screws from loosening, or if you use lubricants or oils on the projector, the projector case may crack and the projector may fall from its ceiling mount. This could cause serious injury to anyone under the mount and could damage the projector. When installing or adjusting a ceiling mount, do not use adhesives to prevent the screws from loosening and do not use oils or lubricants.

■ Do not stand on the projector or place heavy objects on it.

■ Do not use the projector where it may be exposed to rain, water, or

excessive humidity.

■ Unplug the projector from the wall outlet before cleaning. Use a dry

cloth (or, for stubborn dirt or stains, a moist cloth that has been wrung dry) for cleaning. Do not use liquid or aerosol cleaners.

■ Never spill liquid of any kind into the projector.

■ Do not use the projector where it may be exposed to excessive dust or

smoke.

■ Never push objects of any kind through the cabinet slots.

■ Do not use or store the projector or remote control in a hot location,

such as near a heater, in direct sunlight, or in a closed vehicle.

■ Do not block the slots and openings in the projector case. They provide

ventilation and prevent the projector from overheating. Do not operate the projector on a sofa, rug, or other soft surface, or set it on top of loose papers, which could block vents underneath your projector. If you are setting up the projector near a wall, leave at least 7.9 inches (20 cm) of space between the wall and the air exhaust vent.

■ Do not operate the projector in a closed-in cabinet unless proper

ventilation is provided.

■ If you are using two or more projectors side-by-side, leave at least 2 feet

(60 cm) of space between the projectors to allow for proper ventilation.

■ You may need to clean the air filter and vent. A clogged air filter or vent

can block ventilation needed to cool the projector.

■ Do not store the projector outdoors for an extended length of time.

■ Do not use the projector outside the required temperature range of

41 to 95 °F (5 to 35 °C). Doing so may cause an unstable display and could lead to projector damage.

■ Do not store the projector outside the required temperature range of

14 to 140 °F (–10 to 60 °C) or in direct sunlight for long periods of time. Doing so may cause damage to the case.

■ Do not touch the plug during an electrical storm. Otherwise, you may

receive an electric shock.

■ Unplug the projector when it will not be used for extended periods.

■ Unplug the projector from the wall outlet and refer servicing to qualified

service personnel under the following conditions: If it does not operate normally when you follow the operating instructions, or exhibits a distinct change in performance; If smoke, strange odors, or strange noises come from the projector; If the power cord or plug is damaged or frayed; If liquid or foreign objects get inside the projector, or if it has been exposed to rain or water; If it has been dropped or the housing has been damaged.

■ Except as specifically explained in this User’s Guide, do not attempt to

service this product yourself. Refer all servicing to qualified personnel. Opening or removing covers may expose you to dangerous voltages and other hazards.

■ Never open any covers on the projector except as specifically explained

in this User’s Guide. Never attempt to disassemble or modify the projector. Refer all repairs to qualified service personnel.

98 Notices

■ Use the type of power source indicated on the projector. Use of a

different power source may result in fire or electric shock. If you are not sure of the power available, consult your dealer or power company.

■ If you use the projector in a country other than where you purchased it,

use the correct power cord for that country.

■ Do not overload wall outlets, extension cords, or power strips. Do not

insert the plug into a dusty outlet. This can cause fire or electric shock.

■ Take the following precautions when handling the plug: Do not hold

the plug with wet hands. Do not insert the plug into an outlet with dust present. Insert the plug firmly into the outlet. Do not pull the power cord when disconnecting the plug; always be sure to hold the plug when disconnecting it. Failure to comply with these precautions could result in fire or electric shock.

■ Do not place the projector where the cord can be walked on.

■ The lamp(s) in this product contain mercury. Please consult your

state and local regulations regarding disposal or recycling. Do not put in the trash.

■ Do not place anything that can become warped or damaged by heat near

the exhaust vents. Do not bring your hands or face close to the vents while projection is in progress.

■ Before you move the projector, make sure its power is turned off, the

plug is disconnected from the outlet, and all cables are disconnected.

■ Never try to remove the lamp immediately after use because it will be

extremely hot. Before removing the lamp, turn off the power and wait at least an hour to allow the lamp to cool completely.

■ Do not place the source of an open flame, such as a lit candle, on or near

the projector.

■ Do not modify the power cord. Do not place heavy objects on top of the

power cord or bend, twist, or pull it excessively. Keep the power cord away from hot electrical appliances.

■ If the lamp breaks, ventilate the room to prevent gases contained in the

lamp from being inhaled or coming in contact with the eyes or mouth.

■ If the projector is mounted overhead and the lamp breaks, be careful to

prevent pieces of glass from falling into your eyes when you open the lamp cover.

WARNING: The cords included with this product contain chemicals, including lead, known to the State of California to cause birth defects or other reproductive harm. Wash hands after handling. (This notice is provided

in accordance with Proposition 65 in Cal. Health & Safety Code §25249.5 and following.)
