Toner is applied in the following order, using only the colors necessary for a specific image: magenta (M), cyan - HP 3600 | Service Manual - Page 76
Image-formation process Laser printing requires the interaction of several different technologies including electronics, optics, and electrographics to provide a printed page. Each process functions independently and must be coordinated - HP 3600 | Service Manual - Page 77
Figure 4-10 Image-formation steps Latent-image formation stage During the three steps that comprise this stage, a latent image is formed by applying a negative charge to the photosensitive drum. You cannot see this image on the drum. Step 1: pre-exposure The pre-exposure LED hits the photosensitive - HP 3600 | Service Manual - Page 78
