Panel PC Board
This Panel PC Board consists of Panel Control Sub-CPU, LED, and Key Switch.
The Sub-CPU receives the command of async serial data from SC PCB and executes LCD Display, LED
Lamp, Switching Scan, Key Touch Sound, and Alarm Sound. The signal nPSAVE is turned to LOW with the
command from SC PCB and shifts to Sleep Mode. When Sleep Mode (Auto Off) is on, only +5VP is reacti-
vated and +5V (for LED Driver) and +24V (for Status LED and Alarm) is cut off. After detecting the signal
nWAKUP which is input from SC PCB, the signal nPSAVE is turned to HIGH in order to recover from Sleep
Mode and reactivate the main power of the machine.

Laser Printer Motor Drive Circuit
1. System Description
It consists of 16 bit CPU M30802. The CPU controls mechanism of Laser Printer, Fuser Lamp
temperature, and Laser Unit.
temperature, and Laser Unit.
2. Reset Circuit
This circuit consists of IC301 (PST575E) and peripheral circuit. This circuit always watches 5V. Output
of this circuit (nRST) is set that if 5V falls below setting level (3.9V). When the 5V rises above voltage,
the reset signal is canceled after a delay of approximately 20 ms. After cancelling, software is started
by CPU.
