The engine control block (PU) is controlled by the engine control board (K73 PWB) which consists
of a CPU (MSM66Q577), general LSI chip, flash ROM, EEPROM, pulse motor drivers, and video
memory (see Figure 2.3).
(1)
CPU
This, a 16-bit CPU with an AD converter (OKI MIM66Q577), controls the entire system.
(2)
General LSI
This LSI (MG63P011-001LA), which is contained in the printer engine control block,
incorporates 4 megabits of video memory and has functions such as engine-controller
interfacing, LED interfacing, motor control, sensor input, video memory control, main scan
color misalignment correction, skew correction and high-voltage power supply control.
