The Six Steps That a Laser Printer Preforms

A sweeper strip cleans the drum of any residual toner. Erase lamps light the surface of the drum to neutralize any electrical charge left on it.

The primary charging roller conditions the drum with a -600 volts charge.

A laser beam discharges a lower charge only to places where toner should go. The drum retains a -100 volts charge in the spots hit by the laser.

The toner is applied to the drum in the areas where the charge is -100 volts, thus preparing the drums to put the image on the paper.

The transfer charging roller puts a positive charge on the paper to pull the toner from the drum onto the paper. Then the static charge eliminator weakens the charges on both the paper and the drum.

The fusing rollers apply heat to the toner, which melts it, and the rollers apply pressure which bonds the melted toner to the paper.
