More on Development Bias
This machine uses a negative-positive development system, in which black
areas of the latent image are at a low negative charge (about –154
±
50 V) and
white areas are at a high negative charge (about –950 V).
To attract negatively charged toner to the black areas of the latent image on the
drum, the high voltage supply board applies a bias of –650 volts to the
development rollers throughout the image development process. The bias is
applied to the development roller shaft [A] through the drive shaft [B].
The development bias voltage (–650 V) can be adjusted with SP 2201 1.
