DEVELOPMENT
G104 6-48 SM
6.6.4 DEVELOPMENT BIAS
The high voltage supply board #2 supplies development bias to the development
roller through the receptacle at the rear of each development unit.
There are ac and dc bias voltages. The ac bias improves toner transfer to the drum.
The machine automatically controls the dc bias, if automatic process control is
enabled. However, if process control is turned off, (that is, if SP3-501-001 is set to
1), the dc bias is the value stored in SP2212-001 to –009 (do not adjust in the field
unless told to do this).
