Canon NP6218 Manual De Usuario

The copier’s photosensitive drum, developing cylinder, No. 1 stirring rod, and No. 2

stirring blade  are rotated by the drive of the main motor (M1).

The level of the toner inside the developing assembly is monitored by the toner

sensor; when it drops below a specific level, the Add Toner indicator flashes on the
display of the control panel.

The No. 1 stirring rod serves to supply toner to the developing cylinder and stir the

toner flow layer inside the developing chamber.

The No. 2 stirring blade is used to stir the toner inside the toner container and, at the

same time, to supply toner to the developing chamber.

The waste toner collected by the cleaning blade is forwarded by the waste toner feed

blade for collection inside the waste toner assembly.
