The Seven Steps of Laser Printing

Step 4 - Developing

NEGATIVELY CHARGED toner particles are allowed to attach to the PAINTED AREA of the drum; as the negative charge has been drained off these areas.

Step 3 - Exposing

The LASER SCANS or PAINTS the image to the drum. Anywhere the laser touches the drum causes the electrical charge to DRAIN OFF.

Step 2 - Charging

The PRIMARY CORONA WIRE negatively charges the PHOTOCONDUCTIVE drum to 600 to 1000 volts DC.

Step 5 - Transferring

The TRANSFER CORONA WIRE charges the paper with a POSITIVE CHARGE from behind. The NEGATIVELY CHARGED toner jumps to the positive paper, according to the image on the drum. A STATIC CHARGE ELIMINATOR then removes any residual charge.

Step 1 - Processing

The computer sends the data to the printer.

Step 7 - Cleaning

The drum is cleaned of excessive toner and electrical charges.

What are the seven steps of Laser Printing?

The seven steps of laser printing are: 1- Processing 2- Charging 3-Exposing 4- Developing 5- Transferring 6- Fusing 7- Cleaning

Step 6 - Fusing

The toner particles attached to the paper are FUSED or MELTED to the paper, usually with a heated drum.
