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. In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. (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 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 expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.Ģ. In the diagrams, represents the path of mechanical drive where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation. The following rules apply throughout this Service Manual:ġ. Set the cable/wire to the cable guide or wire saddle. Remove the cable/wire from the cable guide or wire saddle.
