Potential control adjusts important elements of the image creation process (drum charge, development bias, and laser output) in order to achieve optimum target image quality.
- Gradation patterns, created on the drum and ITB belt at prescribed times (described below) are read by the ID sensor,
- The potential sensor reads the image from the drum surface, and then these readings are used to determine the development capacity (development gamma)
- Based on these readings, the machine adjusts processing conditions around the drum to achieve the best image quality.
