Introduction
The following rules apply throughout this Service Manual:
1. 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.
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.
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.
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.
The descriptions in this Service Manual are subject to change without notice for product improvement or other
purposes, and major changes will be communicated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant
Service Information bulletins and be able to identify and isolate faults in the machine."

Take note of the following to avoid damaging the PCBs by static charges:
1. Put on a grounded wrist strap before starting the work. If no grounding terminal is found, use the frame of the main
body.
2. Keep each PCB in an anti-static bag until immediately before it is used.
3. When you handle a PCB, be sure to hold the frame of the PCB (i.e., base material area) without touching terminals.
4. If you must place a PCB temporarily, be sure that the area is treated against static charges (e.g., anti-static mat).
Otherwise, place it on or in an anti-static bag. Do not place it on a metal plate.
5. Be sure not to leave insulators which are subject to being charged in the work area.
