Symbols in this manual
The lists of symbols used in this manual are shown below.
The meaning of each symbol described in the table must be understood for proper servicing
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 micropro-
cessor 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 Infor-
mation bulletins.
All service persons are expected to have a good understanding of 
the contents of this Service Manual and all relevant Service Infor-
mation bulletins and be able to identify and isolate faults in the 
machine.

NOTE FOR SERVICING
1. Precautions for servicing
At servicing, be sure to turn off the power source according to the
specified steps and disconnect the power plug.
Do not turn off the power switch when downloading is under way.
Turning off the main power switch while downloading is under way can
disable the machine.
When performing cleaning using organic solvent such as alcohol, be
sure to check that the component of solvent is vaporized completely
before assembling.
– Disconnect the power plug to avoid any potential dangers during
assembling/disassembling works.
– If not specially instructed, reverse the order of disassembly to rein-
stall.
– Ensure to use the right screw type (length, diameter, etc.) at the right
position when assembling.
– To keep electric conduction, binding screws with washers are used
to attach the grounding wire and the varistor. Ensure to use the right
screw type when assembling.
– Unless it is specially needed, do not operate the device with some
parts removed.
– Never remove the paint-locked screws when disassembling.
2. Screw tightening torque
For reduction in weight, thin plates are used in some parts of this
machine.
In the case of a screw hole with a triangle mark near it as shown in the
figure below, strongly tightening the screw may damage or deform the
screw hole.
In the case of a screw hole with a triangle mark, take care not to apply
too much force when tightening the screw.
The recommended torque value is shown below as a reference value.
