All My Junk — In One Place

Cleaning – The Rubber Blade removes any excess toner which drops into the debris cavity. The eraser lamp that removes any excess charge off the photosensitive drum. This leaves the drum with a charge of 0 Volts

Conditioning – The primary corona (High Voltage Wire) adds a negative charge of around -600 volts to – 1000 volts

Writing – The laser light hits the photosensitive drum, where the light hits the drum it dissapates the negative charge to the centre of the drum which is grounded. This then leaves sections of the drum with a voltage of -100 volts

Developing – The drum rolls through a supply of negativly charged toner particles (Particles are -200 Volts to -500 Volts)

Where the drum hasnt been touched by the laser light a lower negative charge is still there, so the particles are not attracted to this section of the photosensitive drum.

Transfer – A strong positive charge is applied the the paper, the particles of toner are attracted to the paper.

Fusing – The toner that is on the paper is heated and pressurised, the toner becomes bonded to the paper.
