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,

name accompanies the symbol

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 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.
