WHAT IT DOES Cleaning Removes prior image information and toner from the drum. Conditioning Applies a uniform negative charge to the drum. Writing Light source such as lasers, LED, or LCS (Liquid Crystal Shutter) write to areas on the drum discharging the negative potential where it hits. Developing The toner is ionized with a negative charge and is attracted to the areas previously written (discharged) on the drum. Transfer The toner of the drum is transferred to the paper by either a positively ionized field (created by a transfer corona wire) or by a transfer roller in newer printers. The toner is not yet permanently set on the paper and requires the last stage. Fusing Heat and pressure are applied to the paper and toner. The toner melts and then is pressed to the paper.
