Copier Parts

Find parts for your photocopier

If you're adventurous enough to take apart your photocopier, you might be overwhelmed by how many different copier parts it has. However, when it comes down to the actual photocopying process, your machine will rely on only a few key pieces. These pieces include the photoreceptor drum or belt, corona wires, lamps, lenses, toner and fuser.

Inside Your Photocopier

The photoreceptor drum or belt is the heart of the system. The drum is basically a metal roller which is covered by a layer of photoconductive material. Since the length of a standard page is a lot larger than the circumference of the drum in a photocopier, one full rotation of the drum will only reproduce a small piece of the page. To duplicate the entire page, the drum has to be cleaned, recharged with ions, exposed to photons and sprinkled with toner numerous times.

In order for a photocopier to work, the corona wires need to generate a field of positive charges on the surfaces of both the drum and the copy paper. The corona wires are subjected to a high-voltage charge which is then transferred to the drum and paper in the form of static electricity.

Making a photocopy requires a light source that has enough energy to boot electrons out of the photoconductive atoms. This is the reason why photocopiers use a plain old incandescent or fluorescent bulb to flash light onto an original document. When the lamp is turned on, it lights up one strip of paper at a time by moving across the inside of the copier.

A mirror attached to the lamp then directs reflected light through a lens onto the rotating drum below. The lens allows you to focus a copy of the image in a specific place, and you can either reduce or magnify the original document by changing the distance between the lens and the drum.

Copier toner, sometimes referred to as dry ink, isn't actually ink at all. It's a pigmented powdery substance. Toner is a fine, negatively charged, plastic-based powder. Inside a photocopier, toner sticks on large, positively charged beads and gets stored in a toner cartridge.

The fuser is then responsible for making the toner image on a sheet of paper permanent. It does this by melting and pressing the toner image into the paper and preventing the melted toner and in some instances, the paper, from sticking to the fuser.

Where to Look for Spare Parts

There are numerous distribution companies that supply a huge range of spare parts for leading brands of photocopiers. These companies regularly stock Canon copier parts, Ricoh copier parts, Sharp copier parts and Minolta copier parts.

You can search for these distribution companies online, and some of them even have copier parts for machines that have been discontinued. On certain company websites, you can search for a particular part using the manufacturer's original part number or browse alphabetically for part types.
