What are toner cartridges made of? What does a printer cartridge contain?

What are the composition structures of toner cartridges?

Different brands or printers used will have different structures and classifications of toner cartridges. General toner cartridges (integrated) will basically include the following components, while split toner cartridges (also known as toner separate drum) are components with only the following components.

OPC Drum:

It is formed by coating the surface of the aluminum cylinder with photosensitive and conductive semiconductor material. It is the heart of the toner cartridge, and other components are centered on it. After charging, exposure and development, a visual toner image is formed on the surface.

Toner Powder:

It is an attachment that melts directly on the printing medium. Different models of toner cannot be universal.

Toner Warehouse:

A warehouse used to store toner. Some toner warehouses have a mixer in order to ensure the smooth supply of toner.

Waste Toner Container:

a warehouse used to store waste toner powder. The toner image formed on the surface of the photosensitive drum cannot be transferred 100% onto the printing medium, and a part of it will remain on the surface of the photosensitive drum. Before the next imaging, a cleaning blade will scrape it off and collect it in the waste toner container.

Cleaning Blade:

Resisting against the photosensitive drum, clean the residual toner that has not been transferred on the surface of the photosensitive drum. The cleaning spatula consists of a metal rack and a polyurethane blade.

Doctor Blade:

consists of a metal frame and a polyester scraper. It evenly controls the amount of toner on the surface of the rod and causes the toner to be frictionally charged.

Primary Charging Roller:

Eliminates residual potential on the photosensitive drum and is responsible for a cylinder composed of a metal shaft and conductive rubber.

Magnetic Roller:

Consists of a magnetic core, a magnetic sleeve and its accessories. During the development process, it attracts the toner surface, and under the control of the doctor blade, forms a layer of toner powder of a specific thickness, and places the toner with a certain amount of friction charge. The charged toner “jumps” through the development bias on the magnetic roller.

Transfer Roller:

The transfer roller is located on the other side of the printing paper. Since it is applied with a voltage opposite to the electrical properties of the toner, the toner on the photosensitive drum is transferred to the paper.

Developing Roller:

It is composed of a metal shaft and conductive rubber. Its function is to absorb the toner, charge it, and transmit it to the surface of the photosensitive drum to produce a visible image.
