Canon MF4452 prompts that the toner is near. What should I do if I can't receive the fax?

Powder adding method for selenium drum:

1, put the toner cartridge vertically, put it vertically in the ring with a small plum-blossom screwdriver, and use the needle-nosed pliers to sell the iron and knock it down until it feels down one centimeter.

2. As shown in the figure, remove the screws in the circle and separate half of the toner cartridge.

3. Remove the drum core and put it away, and dispose of the waste powder bin below.

4. Remove the iron sheet, look at this position and knock out the iron pin from the inside with a small plum blossom screwdriver. You can take down the cover plate of the powder bin and put it away.

5. Reinstall the drum core and charge the drum (for charging the drum core).

6. After installing the drum core, make sure it can rotate in the direction indicated by the arrow.

7. Deal with the powder bin, remove the magnetic roller, clean it and reinstall it. Just put the toner and cover it.

8. Cover the powder bin cover and tighten it. Then put the drum core and the powder bin together and drive the pin from the outside.
