Laser printers because of the large print volume of a single toner cartridge, a toner cartridge filled with toner can print thousands of sheets, which has led to the popularity of laser printers. Many households have also purchased laser printers, so we need to prompt the toner cartridge at each printer. Do I replace the entire toner cartridge when there is no powder?

In fact, it is unnecessary. The printer's toner cartridge is generally composed of three parts: the photosensitive drum, the magnetic drum, and the toner cartridge. Some laser printers are independent of these three parts and can be replaced independently. Many friends will not split it, so they can only replace the entire toner cartridge.

In the actual design of the printer's toner cartridge, the life of the photosensitive drum and the magnetic drum is relatively long, and there is no need to replace it when the toner in the toner cartridge is exhausted. Under normal circumstances, the toner cartridge that has just been replaced can generally print about 2,000 sheets, and the design life of the photosensitive drum can generally reach about 20,000 sheets. Considering that the toner that you replace is a substitute brand, the waste toner rate will be relatively more Higher, so under normal circumstances, the toner cartridge needs to be replaced when the toner is added about 5 times.

At present, the toner cartridges designed by general printer manufacturers are all three-in-one. Adding toner separately is complicated, and the entire toner cartridge needs to be disassembled. This design increases the difficulty of replacing toner, but increases the profit of printer manufacturers. Ordinary personnel will not disassemble. At this time, you need to find a professional to add toner. The replacement toner cartridge usually has a separate powder adding port, which can be added easily just by pulling out the plug.

When adding toner to the toner cartridge, it is best to clean the waste toner. This can increase the life of the printer toner cartridge, because when the waste toner bin is full, the waste toner will stick to the photosensitive drum, resulting in a large area of ​​black when printing. Spots or scratches on the drum.

Therefore, the laser printer does not need to replace the entire toner cartridge each time the toner runs out, which will greatly increase printing costs and cause waste of resources.
