A slide projector is still a popular way to view color slides of a family outing, trips and other memories shot with a camera. But slides often get stuck in the projector's slot because they rely solely on gravity to move them into display position. Removing the jammed slide will keep it from being damaged by the heat of the bulb.
Turn off the slide projector and remove the power plug from the electrical socket. Wait for the bulb to completely cool down.
