Ricoh S-C3 F - Development Bias

Development Bias
Black areas of the latent image on the drum are at low negative charge (about –140 ± 50 V), with white
areas at high negative charge (about –900 V).
To attract negatively charged toner to black areas, the high voltage supply board [A] applies a (default)
bias of –600 V to the development roller [B]. The bias voltage can be adjusted with SP2-201-1.
