Understanding How Photocopiers Function Step by Step: A Simple Guide

Photocopiers are everyday machines that make fast, high-quality copies of documents. But what happens inside when you press that green button? Here’s a step-by-step guide to how photocopiers function step by step, breaking down the process:

Step-by-Step: How a Photocopier Works

Step 1: Document Placement

You place the original document face down on the glass platen (the flat surface), or into the automatic document feeder (ADF) for multi-page copying of multiple documents .

Step 2: Scanning the Document

A bright lamp passes under the document to illuminate the page.
The reflected light (the white parts reflect more, dark parts reflect less) hits a series of mirrors and lenses.
This light is focused onto a photoconductive drum, which is electrically charged and light-sensitive.

Step 3: Creating the Electrostatic Image

The drum is initially given a uniform electrical charge.
As the reflected light hits it, areas corresponding to white lose their charge.
The dark areas remain charged, creating an invisible electrostatic image of your document on the drum.

Step 4: Applying the Toner

Toner (a fine black powder made of plastic and pigment) is attracted to the charged areas of the drum.
The toner clings only to the image areas, forming a powder version of your original document.

Step 5: Transferring the Image

A sheet of paper is fed in and also given an electrical charge.
The toner image is transferred from the drum to the paper using this opposite charge.
Now the toner sits on the paper’s surface but isn’t fixed yet.

Step 6: Fusing the Image

The paper passes through heated rollers called the fuser unit.
These rollers melt and press the toner into the paper fibers, permanently fusing the image.
The result is a crisp, dry, smudge-free copy.

Step 7: Cleaning the Drum

After transferring the image, the drum is cleaned of leftover toner.
It is then discharged and recharged, ready for the next copy cycle.
