Many classrooms now have overhead projectors. If you are looking for a way to make your presentations more engaging, try making transparencies with an overhead projector. This is an easy DIY project that will take less than 30 minutes from start to finish. In this blog post, we will go over how to do it and provide a step-by-step guide!
How To Make Transparencies For Overhead Projector: An Easy DIY Guide
How Do Overhead Projectors Operate?
Overhead projectors are an old form of display technology. They work by shining a bright light through the transparency, onto the screen, and back again to create an image on the wall or board in front of them. The projector shines up at half strength for white images with black text and fills in any gaps between letters with black paint while painting out background colors that would otherwise show up as a blur. In this way, they can be used both for presenting written materials (using transparencies) as well as visual presentations such as maps or graphs (by projecting from film).
How Do I Make Transparencies?
Step One:
Print your document or create a digital copy. If you are printing, we recommend using high-quality materials and inks to ensure that the transparencies will be as clear as possible. Consider double-sided pages so that each of them can have two overlaid images on it – one for the top layer and one for the bottom layer.
You might also want to try adjusting the contrast settings on your printer if you find they don’t show up well with other overhead projectors (this is particularly true when making posters). Ideally, use a laser printer (or toner transfer) rather than an inkjet printer since these tend not to smear over time like inkjets do.
If you’re creating a digital version of your transparency, use a high-quality resolution and create it from two different screens to ensure that the colors will show up correctly.
Step Two:
Take your document or digital file over to an overhead projector – you might want to put it inside of a clear plastic sleeve so as not get finger prints on the paper while handling it. If possible, turn off all other lights in the room before placing your transparencies into place for best results.
Step Three:
Turn on the light by pushing down on its top switch (many have multiple switches). The “Up” button should be pushed if you are working with color images; this is because they usually do not display well when projected onto black boards and need more contrast than text documents.
Step Four:
Magnify the image by turning up its “Lens” knob until you see a clear, readable picture on your screen or wall. Notice that each increment is marked with a number and this corresponds to how much it has been turned so far (e.g., if you turn it all the way around once, then “0” will show). You may need to adjust these increments depending on what type of projector you are using – some might require larger magnifications than others do for optimal viewing quality.
Step Five:
To increase contrast between text and background colors, use the “Contrast” control knob next to the lens setting until they look perfect together again. If there’s still too much color in the background, you might want to switch between black and white until they look right.
Step Six:
Turn your projector off by pressing down on its top switch again once it has been lit up (most of them have multiple switches). The “Up” button should be pushed if you are working with color images; this is because they usually do not display well when projected onto black boards and need more contrast than text documents do.
How to Print From PowerPoint to an Overhead Sheet
If you need to present a slideshow of images or text, but for some reason don’t have the right transparency material on hand then there is an easy solution: You can print your PowerPoint slides directly onto overhead sheets.
- Step One: Open up Microsoft’s Office suite and go to “File” > “Print.” Then select which printer you will be using and click on the “Options” tab.
- Step Two: Next, select “Scale to Fit Paper Size” and change it to Overhead Transparencies (requires a paper size of 16×20 inches). You may need to adjust this setting depending on what type of projector you are going to be projecting from – some might only be able to project images of a smaller size.
- Step Three: After clicking on the “Print” button, you will go back to your PowerPoint and see that your slides have been printed onto an overhead sheet already! This is perfect for when you need them quickly or don’t want to wait around for inkjet printer cartridges to dry.
Multi-Purpose Transparency Film
Transparency film is a type of clear plastic sheet that can be used for many different purposes, such as printing onto it and then displaying the image through an overhead projector.
Device-Specific Films
Most transparency films are designed to work with one particular device (such as CRT projectors); this allows you to find out which ones will best suit your needs and which ones will work with the projector you have.
Transparency Films with Stripes
Some transparency films also come in a striped variety that do not need to be flipped since they are already clear on both sides; these can just be placed over text or images like an overhead sheet, although this type is generally less common than others.
Paper-Backed and Thick Transparency Films
Some transparency films are made out of thicker, more durable material than others; these might be better for presentations that will only need to last a short amount of time (such as the first few minutes) or if you’re going to print onto them with an inkjet printer. They have one major downside, however: Once they are printed onto and then displayed through an overhead projector, the text or images will be upside-down.
How to Clean a Printer Fuser
The fuser is what heats up in order to melt toner on paper so that it sticks together and makes ink. Sometimes this can get dirty over time which causes your printer to spit out dirty, smeared pages.
- Step One: To clean your fuser head you will need a glass bowl or other deep dish and some cool boiled water. After unscrewing the two screws on the inside of the printer where it meets with its cover (located near the back) pour in enough hot water to cover the fuser head and allow it to sit for about an hour.
- Step Two: After waiting, turn off your printer’s power knob (located near the top) so that you don’t accidentally try to use it again while it is still wet from being cleaned. Remove the water from inside by pouring a glass of cool water over the fuser head.
- Step Three: Next, take a paper towel or some other cloth and press it down on top of the fuser to soak up any excess water – this might take awhile depending on how much water was in there originally. Use another dry piece of cloth to continue wiping off until you can’t see any more water droplets.
How to Keep Slides From Jamming in a Projector
The main cause of slides becoming jammed in projectors is that the paper isn’t as durable and strong enough for them, so it starts to tear apart when inserted into the projector’s tray while being played. To prevent this from happening you will need some type of clear overlay.
How to Restore Factory Settings on a Zebra Printer
If you want to, say, return your Zebra printer to it’s factory settings or revert any changes that have been made since the last time it was on the default setting then here are a few steps you can take:
- Step One: Resetting your printer is as simple as pressing one button which will erase all of your settings and revert them to the default, original settings.
- Step Two: Press “Reset” then hold down the power button for a few seconds until you see that it has been reset (this will be indicated by two lines of green text on your LCD screen).
How to Remove Paper Stuck in Allegheny Shredder Cutters
The holes in Allegheny shredder cutters can get jammed up with paper, especially if you don’t use them often or if the paper wasn’t folded before being inserted. To remove it:
- Step One: Open your machine and check to see where the papers that are stuck are located; this will be indicated by a little flap that is sticking up from the surface of your machine.
- Step Two: Push down on this flap and pull out the paper; then, close it back up again to resume normal use.
Physical Specifications
The physical specifications of a projector are the measurements and technical details which determine how it will fit into your home or business. There are many different types, sizes, brands, wattage ratings, etc., so you’ll want to make sure that this is something you can accommodate before making any purchase decisions.
Dust Control
One important aspect of any projector is how it deals with dust. Without a way to keep this from accumulating inside, the machines are more likely to malfunction and have issues displaying images properly. There are two main types of control for keeping your machine clean:
- Step One: The first type is an automatic filter that will suck up any excess particles; these filters come in many different sizes and are usually purchased separately from the machine.
- Step Two: The second type of dust control is a vent system which consists of an outside fan that forces air inside to distribute it out – this option requires you have either a window or door open on your projector’s side for ventilation purposes.
Temperature Control and Electrical Connections
The two most important aspects of a projector are the temperature and its electrical connections. This is especially true if you’re using your projector with an extension cord as it will create more heat than one that plugs in directly
Styles and Availability
If you want to make sure that you have enough light for what type of presentation or event, then there are several different styles of projector to choose from.
