Selenium drum, also known as photosensitive drum. It is the most important part of the laser printer, which determines the quality of our printing and our spending on printing. The selenium drum is mainly made of aluminum and some light-sensitive materials, and its working principle is the process of photoelectric conversion. At present, we divide toner cartridges into three categories, just like the light-sensitive materials selected for toner cartridges. They are OPC drums (organic photoconductive materials), selenium drums (Se Se) and ceramic drums (a-si ceramics). Among the three categories, OPC drum has the shortest service life and ceramic drum has the longest service life. Secondly, the prices of the three products are different, and their prices are determined according to their service life.

At the end of the article, I want to give you a warm reminder: when the toner cartridge fails and we need to replace it, there are generally three choices: original toner cartridge, universal toner cartridge (compatible toner cartridge) and refilled toner cartridge. The prices of the three toner boxes are naturally the most expensive and the best quality of the original toner boxes. However, for personal use, the recommended universal toner cartridge has moderate price and good performance. For office or collective use, the original toner cartridge should be selected naturally. As for the cartridge, although the price is low, the print quality is too poor, which is beyond our consideration.

This is what I brought to you today. Choosing a good toner cartridge means choosing a good laser printer. Do you still remember?
