Transfer belt control
During secondary transfer, the controller board activates the transfer
belt press clutch (CL4). The transfer belt is normally away from the
transfer drum, except while pushed against the transfer drum during
secondary transfer. When the secondary transfer is complete, the
transfer belt is removed from the transfer drum when the controller
board sets the CL4 to off.
