II. ENGINE CONTROL SYSTEM

A. Engine Controller PCB
1. Outline

The operation sequences of this printer are controlled by the CPU of this circuit. When the
power switch of the printer is turned ON and the printer enters the STANDBY mode, the CPU
outputs the signals to drive the loads such as laser diode, motors, and solenoids, based on the
print commands and the image data input from the external device.

Figure 2-2-1 shows the block diagram of this circuit.
