What is a toner cartridge? What do you use it for on your printer?

You must know that selenium is more expensive than selenium, if the main ingredient is selenium, who else can use it! The reason why it is called toner cartridge is that when it was just born, it used inorganic material - selenium material to make photosensitive drums.

Selenium is allowed to adhere to the drum base through evaporation to make a photosensitive drum. After the 80s, the photosensitive drum has been made of organic light guide materials, which is cheap and less polluting. However, since everyone is used to it, they still call the photosensitive drum "toner cartridge".

Toner cartridges are used in a very wide range of laser printers.

Photocopiers and fax machines.

The basic structure of the toner cartridge consists of a basic substrate made of aluminum, and a photosensitive material coated on the substrate. According to the different photosensitive materials, it can be basically divided into three types: OPC drum (organic light guide material), toner drum (SE selenium) and ceramic drum (A-Si ceramic).

In terms of life, the life of OPC drums is shorter, generally only about 3000 pages, and of course, it is also the cheapest. The life of the SE drum is about 9,000 pages, and the life of the A-Si drum can reach 90,000 pages. In terms of composition, the average OPC toner cartridge has only three layers.

The first layer is the aluminum tube, the second layer is the insulating layer, and the third layer is the photosensitive layer. The surface of the toner cartridge (SE selenium) and ceramic drum (A-Si ceramic) is synthesized from four or five layers of substance. Especially for ceramic drums, its fourth layer is the first protective layer, and the fifth layer is the second protective layer.

The fourth and fifth layers are used to protect the photosensitive layer.

In terms of structure, there are two types of toner cartridges: integral (or integral) and separate. The integrated toner cartridge is to install the toner cassette and the photosensitive drum on the same device, and when the toner is used up or the photosensitive drum is damaged, the entire toner cartridge must be scrapped. The models that use these toner cartridges are mainly HP and Canon models.

The detachable toner cartridge toner and photosensitive drum are placed on different devices, and the life of the photosensitive drum is generally very long, generally reaching the life of 20,000 sheets. When the toner runs out, just replace it with a new toner, so that the user's printing cost is greatly reduced. The main ones that use this toner cartridge are Panasonic, Epson, etc.

Whether it's a laser printer, copier, or fax machine, toner cartridges are a vital component. It is not only related to the printing quality of the product but also related to the cost of using the product, and the user must understand the toner cartridge of the product when purchasing the product.

The toner cartridge is used to provide powder ink to the laser printer, also known as the photosensitive drum, which is generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. The toner cartridge not only determines the quality of the print, but also determines the amount of money that the user needs to spend in the process of using it.

The greater the amount of paper that can be printed, the longer the cartridge lifespan. The length of the cartridge life is determined by the drum. For small and medium-sized office users with relatively difficult printing tasks, they should be willing to pay more purchase costs for higher monthly printing load (more than 10,000 pages) and long-life toner cartridges (up to 20,000 pages) - the reliability of models with higher indicators is generally more prominent, otherwise paper jams and even "lying in the nest" and frequent replacement of toner cartridges will greatly reduce printing efficiency, increase maintenance and overall printing costs.
