Introduction to consumables of laser printer

The consumables of laser printer are mainly composed of toner, photosensitive drum (also known as selenium drum) and printing paper. Some models of laser printers have an integrated structure of toner and photosensitive drum, while some models have separate photosensitive drum and toner, which are all installed in the toner cartridge. When the toner in the cartridge is used up, the entire toner cartridge can be removed and replaced.

Toner is the main consumable of laser printer, and its quality will directly affect the final quality of printing. Therefore, users must choose high-quality toner when replacing toner.

The photosensitive drum is the core of the whole image generation system, and also the core component of the laser printer. The base of the photosensitive drum is aluminum alloy. It is an aluminum alloy cylinder, and the surface is covered with a layer of organic compound - photosensitive material. The surface of the photosensitive drum is very smooth, and the geometric accuracy is very high. Since selenium tellurium alloy is mostly used on the surface of the photosensitive drum, it is also known as the selenium drum. The rated life of the photosensitive drum is generally about 6000-10000 prints. When the print quality is uneven, if it is not the toner, it is necessary to consider replacing the drum. However, the drum replacement must have professional knowledge and cannot be operated casually.

The printing paper of the laser printer is generally electrostatic copy paper, which is made of chemical wood pulp. It has extremely fine surface roughness, smoothness, controllable electrical properties and thermal stability, which can ensure that the laser printer can obtain good printing results If the paper used by the user is color paper, it must be of the same quality as the white copy paper, and the pigment of the color paper must be able to withstand the high temperature of 200 ℃ printing operation for 0.1 seconds without fading. The forms printed in advance by users must be printed with flame-retardant and heat-resistant ink, which must also be able to withstand the high fusion temperature of 200 ℃ printing operation for 0.1 seconds, and not melt, volatilize or emit harmful gases.
