Latent-image f ormation bloc k During the latent-image formation stage, the laser scanne r forms invisi ble images on the photosensitive drums in the print cartridges. Pre-exposure Step 1 : Light from the pre-exposure LED strikes the photose nsitive drum surface. This eliminates the residual electrical c harges on the drum surfac e. Figure 1-14 Pre[...]

Laser beam exposure Step 3 : The laser beam scans the photosensitive drum to neutralize negative ch arges on parts of the drum surface. An electrostatic latent image is formed on the drum wh ere negative charg es were neutralized. Figure 1-16 Laser beam exposure Laser beam 30 Chapter 1 Theory of operation ENWW[...]

Developing block Step 4 : In the print cartridge, toner ac quires a negative charge from the friction that occurs when the developing roller rotates against the developing blade. The developing bias is applied to the developing roller to create a difference in the el ectric potential of the drum. When the negatively charged toner comes in contact w[...]

Transfer block Primary transfer Step 5 : The toner on the photosensitive drum is transfer red to the intermediate tr ansfer belt (ITB). The ITB is given a positiv e charge by the bias o f the pr imary transfer roller. The negatively charged toner on the drum surface is transferred onto the ITB. All four color planes ar e transferred onto the ITB in[...]

Separation Step 7 : The elasticity of the paper and the curvature of the secondary transfer opposed roller cause th e paper to separa te from the ITB. The static charge eliminator reduces back si de static charge of the paper and c ontrols excess dis charge after th e transfer pro cess for stable media feed and i mage quality. Figure 1-20 Separatio[...]

ITB cleaning block Step 9 : The cleaning blade scra pes the re sidual toner off the surface of the ITB . The residual toner feed screw deposits resid ual toner in the toner collection unit.
