What is a toner cartridge
A plastic housing that contains toner powder
7 steps to laser printing which is called the Electrophotographic (EP) printing process
Processing, Charging, Exposing, Developing, Transferring, Fusing, Cleaning
Laser Printing Processing
The OS uses a print driver to translate what’s on the screen to print
laser printing charging
The imaging drum is conditioned with the primary charge roller
laser printing exposing
The surface coding of the photosensitive imaging drum loses its charge when exposed to light
laser printing developing
The laser printer takes the toner and applies it to a developer roller
laser print transferring
Moving the toner from the imaging drum into the print media, usually a piece of paper
laser print fusing
The fuser squeezes the paper between a hot roller and a pressure roller

Tips for getting extra prints out of your cartridge
Shake it around, the toner is very fine and so the lower capacity warning may just be due to the location of the toner powder
