2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.

In practically all cases, the internal mechanisms of a microprocessor cannot be checked

in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC

controller PCB and from the output of the DC controller PCB to the loads.

Points to Note About Turning Off the Main Power Switch

This machine has two switches related to power supply, the Power switch and the breaker. Turning on the Power switch powers this machine.

The breaker detects an excess current and electric leakage to protect you against an electric shock.

MEMO: Explain to the customer that the breaker must be checked once or twice a month and the result

must be recorded.

The components of this fold unit are organized into three major blocks: tray unit,Paper feed

unit and Feed unit.

Overview of Electrical Circuitry

The machine's sequence of operations is controlled by the DC controller PCB.

The DC controller PCB is a CPU used to interpret input signals from sensors and host machine and

generate signals to drive such loads as motors and clutches at such times as programmed in advance.
