What is the difference between the toner cartridge and the drum unit?

The toner cartridge and drum unit are different consumables. They are used in Brother equipment and require two consumables.

The ink cartridge mainly refers to the component used in the ink jet printer to store the printing ink and finally complete the printing. The internal storage is ink, which, as the name suggests, is a liquid substance. From the point of view of the composition of the ink cartridges currently on the market, in general, it can be divided into: a split type ink cartridge and an integrated ink cartridge; the toner cartridge contains powder (toner) for creating letters and images. You need to replace the toner cartridge when the toner is low or the print quality deteriorates due to toner deterioration.

A toner cartridge, also called a photosensitive drum, is generally composed of a base substrate made of aluminum and a photosensitive material coated on the substrate. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the quality of the print is actually determined largely by the toner cartridge. So the toner cartridge is the most critical part of the laser printer; the drum unit transfers the toner to the paper. The laser printer places toner on the “drum”roller inside the drum unit, and then heats and presses the toner to the paper to print letters and images. In order to maintain good print quality, the Brother machine automatically detects the deterioration of the drum unit quality. If the Brother machine displays the “Replace Cartridge” error message, you will need to replace the drum unit.

The toner cartridge is used in laser printers and is printed with toner. The ink cartridges are used in ink jet printers, and the inks are used. The range of products is different. Laser printers rely on laser imaging. Ink jet printers rely on ink imaging. The imaging principle is also Not the same; the toner cartridge is powdered, and the ink cartridge is filled with ink. The ink cartridge can be used as a supply, and the toner cartridge cannot.
