  • Page 397: Step 1: Charge

    7558-xxx Step 1: Charge Previous Voltage is sent from the high-voltage power supply (HVPS) to the charge roll, which places a uniform negative electrostatic charge on the surface of the drum.

    7558-xxx Step 4: 1st Transfer Previous When the latent images are developed on each photoconductor, the high-voltage power supply sends voltage to the 1st transfer rollers inside the transfer belt. The charge difference between the developed toner image on the photoconductor surface and the 1st transfer roller causes the images to transfer to the surface of the transfer belt for each color.
