Image formation process Each of the following processes functions independently and must be coordinated with the other product processes. Image formation consists of the following processes: Latent-image formation block Step 1: pre-exposure Step 2: primary charging Step 3: laser-beam exposure - HP Color LaserJet Enterprise CP5525 | Service Manual - Page 53
Latent-image formation block During the latent-image formation stage, the laser scanner forms invisible images on the photosensitive drums in the print cartridges. Pre-exposure Step 1: Light from the pre-exposure LED strikes the photosensitive drum surface. This eliminates the residual electrical - HP Color LaserJet Enterprise CP5525 | Service Manual - Page 54
Laser beam exposure Step 3: The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum surface. An electrostatic latent image is formed on the drum where negative charges were neutralized.

blade. The developing bias is applied to the developing roller to create a difference in the electric potential of the drum. When the negatively charged toner comes in contact with the photosensitive drum, it adheres to the latent image because the drum surface has a higher potential.
