5.2 Develop Roller / Developing Bias Voltage Counter Reset Function
Since print density is likely to become darker as the toner gets older, the developing bias is
lowered by degrees (bias voltage is reduced) according to the number of develop roller
rotations so that an almost fixed density can be maintained from the beginning to the end.
The developing bias voltage can be verified in the display of log information (Function code
80).
In the case that the toner cartridge is replaced with a new one, the develop roller counter and
developing bias voltage are reset at the same time. This function allows you to reset these
manually.
