How can I focus it other than using the focus knob


The focus knob is the way you focus overhead projectors. Perhaps you simply haven't turned the knob far enough? How far is the projector from the screen? If it's quite close, you need to turn the knob to raise the lens. If far away, turn it to lower the lens.

Overhead Projector Tip- best results!!


For best results, slant the screen forward slightly so it meets at a 90 degree angle with the projected image light beam. In not, then a keystone effect results where the projected image is taller on top or on the sides; in other words, the projected image is a parallelogram, not a square.

Some people switch the projector on and off to shift the focus of the audience from the image back to the speaker. This also saves the lamp. This is a matter of personal presentation style.

Move the projector away from the wall, the picture gets bigger. Then use the focus knob at the top to get a clear picture on the wall. Then use a camera to take a picture of the wall. Then upload the picture to the place you want to transfer it to.

When I turn on the overhead projector it displays picture on the ceiling. Need to adjust to show on the wall. Do not have a manual.


Hi! This is a pretty common problem with overhead projectors. At the top of the arm that's over the unit, there should be a lens unit. The unit needs to be rotated so that one lens points down, and one lens points towards the screen. Once the lens is rotated properly, the lens unit is moved up or down in order to focus. There's usually a knob to turn to move the lens up or down.

One general rule about projected image size: judge the distance between screen and farthest viewer, divide by six and use this number to figure image width.

The auto focus won't focus on images from far away, 2 feet. It only focuses at 2-3 inches


Most CMOS web-cams have a focusing ring round the lens which rotates to give you basic adjustment - after that the auto-focus should sharpen up the image

What is an Overhead Projector?


An overhead projector is a very basic but reliable form of projector. The overhead projector displays images onto a screen or wall. It consists of a large box containing cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen.
An overhead projector can be used to enlarge images onto the screen or wall for audiences to view.
