Place the toner cartridge in front of you as shown in the picture. Melt a 10mm hole in the cartridge at the point marked below with the help of a soldering iron. Fill the refill toner into this hole with the help of a funnel (you will receive it with your order). Seal the hole with a piece of tissue tape. The cartridge is now full. If you want to fill your cartridge for the second time, you should empty the waste toner box (Please ensure that you always wear a mask and gloves when emptying). To do this, melt a hole at the point marked below. Keep the cartridge in a trash bag. Now turn the cartridge so that the residual toner can flow out of the cartridge. The waste toner cannot be reused
