2.3.2.7 Fuser Drive Board
The FDB (Fuser Drive Board) controls 2 halogen lamps in the fuser unit using control signals which are
provided from the ENGINE PBA and supplies AC power to the SMPS. Both V1/V2 FDBs provide max.
1500W output power.
When the phase signal of AC Power goes to zero, the FDB sends a zero-crossing detect signal to the
ENGINE PBA. The zero-crossing output consists an open-collector node.
