The drum unit the core photosensitive part of toner cartridge, and the high-quality cartridge can bring a good printing effect, especially at the print level. The poor quality of toner cartridges, due to the use of lower-cost drum unit, has a direct impact on the short drum core life. Maybe you didn't realize the difference when you first started printing.

Only when the toner is nearly depleted will there be a reduction in print darkness.
