Transfer Bias Constant Current Control
The transfer bias control circuit on the DC controller PCB controls the transfer bias applied to
the transfer roller to keep the constant current.
● Transfer bias level control
The transfer bias output varies according to the environment, paper type, paper width, and/or
source of paper detected by the environment sensor (HU1).
