ABSTRACT:
A laser beam printer operatively responsive to a printing signal fed from a host control unit includes a printing unit for executing a xerographic process, a laser beam scanning unit, a fusing unit, a process control unit for controlling said printing unit, the laser beam scanning unit, and the fusing unit, and a signal processing unit for receiving the printing signal from the host control unit. When the host control unit begins to supply a printing signal to the signal processing unit, the signal processing unit supplies a provisional start signal to the process control unit. Upon receiving the provisional start signal, the process control unit controls the printing unit, the scanning unit, and the fusing unit to bring them into a ready state.
