Note: Removing or Inserting the Lamp (Sticking of Packing Ring)
After lamp replacement, a black packing ring may be stuck inside the projector (Fig. A and Fig. B).
If this happens, do the following:
• If the used packing ring does not remain inside the projector (Fig. C), proceed with the new lamp housing installation.
• If the used packing ring is stuck inside the projector (Fig. B), remove it from inside the projector before installing the new lamp
housing. To remove the packing ring, simply pull it off of the stud.
* In other cases where the lamp is removed (other than lamp replacement), pulling out the lamp housing may also cause the
packing ring to stay stuck inside the projector. If this happens, make sure to insert the lamp housing back in its original position.
CAUTION
• Before removing the used packing ring, be sure to turn off the projector, wait for the cooling fan to stop, disconnect the power
cable, and allow at least one hour for the lamp to cool.
The projector can become very hot when it is turned on and stay hot immediately after it is turned off.
• Do not install a new lamp with the used packing ring stuck inside the projector as it requires excessive force to install the new
lamp which then may cause damage to the projector.
