Performing routine maintenance
Getting the projector status
To get the projector status:
SPress the enter button on the projector or remote control and go to Help.
This screen shows information and status for the projector.
Cleaning the projector and lens
You can clean the projector housing using a soft, dry cloth.
You can clean the front lens of the projector using the following recommendations. You cannot 
clean any of the internal surfaces.
•To minimize the risk of damaging or scratching the lens surface, blow dust particles off the 
lens with clean, dry, deionized air.
•If this method does not work, use the following method:
a.Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and forth 
across the lens.
b.If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still dirty after 
washing it or the fabric is damaged, replace it.
CAUTION:Cleaning requires special consideration:
•Do not spray any type of fluid or cleaner directly on the lens surface. Cleaners might 
damage the lens.
•Do not use fabric softener when washing a cleaning cloth or softener sheets when drying 
the cloth. Chemicals on the cloth might damage the surface of the lens. 
•Do not store a cleaning cloth in contact with the lens for a long time because doing so 
contaminates the lens with dye from the cloth. The cloth can be contaminated if left in the 
open air. 
						

							Maintaining the Projector 42
Replacing the lamp module
As the projector operates over time, the brightness of the projector lamp gradually decreases 
and the lamp becomes more susceptible to breakage. You can install a new lamp at any time 
to bring the projector up to factory-fresh brightness. We recommend replacing the lamp if a 
warning message is displayed.
WARNING!Replacing the lamp module requires special consideration:
•To reduce the risk of injury, be careful when removing the lamp module as broken glass 
might be present. If the lamp is broken, contact HP about repairs that might be required 
due to glass fragments. 
•This digital projector lamp contains a small amount of mercury. If the lamp breaks, 
adequately ventilate the area where the breakage occurred, discard any nearby food and 
drink, and thoroughly clean the table surface around the projector. Wash your hands after 
cleaning the area or handling a broken lamp. Disposal of this lamp may be regulated due 
to environmental considerations. For disposal or recycling information, please contact your 
local authorities or the Electronic Industries Alliance (www.eiae.org). You can find safety 
information about the lamp at:
www.hp.com/hpinfo/globalcitizenship/environment/productdata
•Because the lamp assembly operates at a very high temperature, wait 30 minutes before 
removing the lamp module.
1.Turn off the projector and allow it to cool for 30 minutes.
2.Unplug the power cord.
3.Turn the projector over onto a soft surface.
4.Loosen the two screws 
1 holding the lamp cover and remove the cover.

5 Installing Permanently
Installing the projector
Choosing cables
If you are permanently installing the projector or using it with long cables, consider the 
following suggestions when planning the installation:
•Use high-quality cables. Use only video cables that are made with 75-ohm coaxial cable 
and connectors. For high-resolution video, use low-loss video cables.
•Minimize cable length as much as possible. For video cables longer than 6 m (20 ft), use 
low-loss coaxial cables.
•Do not run audio or video cables next to power or network cables. If they must cross, cross 
them at 90 degrees.
•If you are installing cables in walls, use cables with necessary approvals, such as 
Underwriters Laboratories (UL) approval.
•If you are running cables above a dropped ceiling, you must use plenum-rated cables if the 
space above the ceiling is open to the space above other rooms. You must use plenum-
rated cables if you are running cables in a duct.
•Before installing cables permanently, check the setup with the final cables in the open.
Installing on a table
This installation is covered in detail in Chapter 1. See “Setting up the projector” on page 13 
for more information. 
						

							Installing Permanently 48
Installing for rear projection
1.Place the projector 1.5 to 10 m (5 to 33 ft) behind a translucent screen that is designed for 
rear projection.
See “Setting up the projector” on page 13 for more instructions.
2.Press enter, 
, ,  , go to 
    Setup > Picture orientation. Then select Rear Normal.
Locking the projector
The projector includes a built in slot to secure the projector with a cable and lock (such as the 
Kensington MicroSaver lock system, available at many computer stores). 
1.Wrap the cable around a secure object, such as a table leg. Loop the cable to create a slip 
knot around the stationary object, and be sure it cannot slip off.
2.Insert the lock 
1 into the hole and twist the key 2.

additional information. To contact HP, refer to the support guide included with the projector.
Warning light problems
If both red warning lights are blinking:
• Allow the projector to cool down after it turns off. If this condition occurs after you 
restart the projector, an internal component has failed. Contact HP for assistance.
If the red temperature light is on or blinking:
• Allow the projector to cool down after it turns off. Be sure that nothing is near or 
blocking the vents on the projector, and that the vents are free of lint and other objects. 
Remove any sources of excess heat in the room. Observe temperature and altitude limits 
(see “Specifications” on page 55). If the warning light turns on or blinks after you 
restart the projector, contact HP for assistance.
If the red lamp light is on or blinking:
• Allow the projector to cool down after it turns off. If the warning light turns on or blinks 
after you restart the projector, remove and reinstall the lamp module.
• Install a new lamp. If this occurs after you install a new lamp module, remove and 
reinstall the lamp module. If a new lamp does not fix the problem, contact HP for 
assistance. 
						

							Fixing Problems 50
If the red lamp light is flickering quickly:
• Check that the cover over the lamp is correctly installed and fully attached.
Start-up problems
If no lights or sounds turn on:
• Be sure that the power cable is securely connected to the projector and the other end is 
plugged into an outlet with power.
• Press the power button again.
• Unplug the power cord for 15 seconds, then plug it in and press the power button 
again.
Picture problems
If a “scanning” or “waiting” message is displayed on a blank screen:
•Press the source button on the projector or remote control one or more times until the 
correct source name is selected.
• Be sure the external source is turned on and connected.
• For a computer connection, ensure your notebook computer’s external video port is 
turned on. Refer to the computer manual. On some notebooks, for example, press the 
F
N+F4 or FN+F5 function keys to turn on the external video port.
If the wrong input source is displayed:
•Press the source button on the projector or the remote control one or more times to select 
another active input source.
If the image is out of focus:
• Be sure the lens cover is removed.
• While displaying the on-screen menu, adjust the focus ring. (The image size should not 
change; if it does, you are adjusting the zoom, not the focus.)
• Ensure the projection screen is 1.5 to 10 m (5 to 33 ft) from the projector.
• Check the projection lens to see if it needs cleaning.
• For a computer connection, set the display resolution as the computer to the same 
resolution as the projector, 1024 × 768 (see “Specifications” on page 55). If the 
computer has multiple monitors, adjust the resolution of the monitor assigned to the 
projector.
• For a computer connected to the S-video port, the picture cannot be as high resolution 
as what you see on the computer display.
