Image-formation system The image-formation system, which forms a toner image on media, consists of several interdependent systems. Figure 18. Image-formation system 88 Theory of operation ENWW - HP 2300d | Service Manual - Page 91
Image-formation process Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation - HP 2300d | Service Manual - Page 92

Step 1: primary charging Step 2: laser-beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum.
