You are suddenly low on toner and need to replace the cartridge but you don’t know where to start. Before doing the next step, know some important things first!
Always be mindful when you are low on toner. When the print is faded, it’s already a sign to replace. It is always a good practice to replace your cartridge right away.
Don’t be confused between the drum unit and the toner cartridge. The drum unit is where you’ll find the toner cartridge. It’s black in color and what you will usually see first once you open the cover of your printer.
