🤔 How it works …….. ⁉
How a Laser Printer works 🖨️
Laser printers🖨️ include not only laser but also contain rotating cylinder coated with photosensitive electrically charged material and series of mirrors. When you are sending a document to a laser printer, laser light is reflected by the mirrors on to the cylinder which neutralizes electric charges in specific areas.
The rotation of both cylinder and the mirrors, as well as the lasers are turning on and off at precisely correct moments the areas hit by the laser correspond to the actual print. So when the toner particles hit the cylinder they only stick to the areas exposed to the laser light, because the toner itself has an electrical charge too.
Then a sheet of paper is pressed against the cylinder and the toner is transferred through the paper using heat which fuses a toner to it. That is why pages right from the laser printer are always warm.
😳Why❓❓❓
Why ice floats on water 🧊🌊
Ice floats because it is less dense than liquid water. Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top.
