6.12.5 TRANSFER BELT CHARGE
Mechanism
The high voltage supply board [A] applies a positive current to the transfer belt [B]
through the terminal block [C], terminal plate [D], and the bias roller [E].
The high voltage supply board adjusts the current to the roller to keep a small but
constant current flow to ground through the belt, paper, and drum. If this current is
not kept constant, efficiency of toner transfer and paper separation will vary with
paper thickness, type, environmental condition, or changes in transfer belt surface
resistance.
