Then, a latent image is formed on the drum surface by constant-speed rotation of the photosensitive drum and constant-speed - HP Color LaserJet 9500 | Service Manual - Page 164

The laser driver IC then performs the automatic emission control of the laser diodes (APC), the image mask control, and a forced light emission of each laser diode.
