Development Bias

Development bias is applied from the combined high-voltage power supply board to the development sleeve shaft [A].

For MP C6503/C8003, the toner is developed by applying the DC bias as in previous models.

For Pro C5200S/C5210S, the development method differs depending on the colors. For K , the toner is developed by applying the DC bias in the same way as MP C6503/C8003.

For Y/M/C colors, the toner is developed with the RP (Return Pulse) development method. The toner on the surface of the drum is made level by applying the return bias as shown below, so that the color/density unevenness problem, which appears at the same interval as the drum circumference, is improved.
