B
Parts that may become faulty
accidentally and have a relatively

C
Parts that have a sufficiently long
MTBF, but are expected to have
a relatively high failure rate.
D
Parts that have a sufficiently
long MTBF, but are expected to
become faulty.
E
Parts that are necessary for fault
analysis, or parts that may be
needed in case of unexpected
accidents such as man-induced

■ REF.NO.
REF. NO. is a parts number indicated in the
Service Parts Exploded Views. For parts
having different functions, they are clearly
distinguished in the REMARKS and SERIAL
NUMBER columns.
■ PART NUMBER
PART NUMBER is a code number that is
unique to each part. An alphabetic letter at
the right-most position of the code number
has the following meaning.
○ For hardware
The alphabet denotes the version number
of a part. If parts have different version
numbers, they are upward-compatible.
○ For software
The alphabet denotes a difference in the
specifications. Parts differing in the suffix are
not compatible with each other. Although
the version is indicated by a number, it is
omitted.
■ PART NAME
PART NAME represents a general name of
a part.
■ QTY.
○ QTY. denotes the quantity of parts used
in each unit.
○ A parts with -S assigned to the end of
the quantity represents a small part that is
shipped in packs of 50. (Even if such a part
is ordered in quantity of 1, a pack containing
50 pieces of that part is supplied.)
■ REMARKS
The REMARKS column indicates a unique
name of a part or its relevant information of
note.
■ SERIAL NUMBER
The u ni t s ma y co nta in di ffer ent p ar ts
depending on their shipment control number.
SERIAL NUMBER indicates the shipment
control number to which the relevant parts
are applicable. If the SERIAL NUMBER
column is blank, the parts are applicable to
all the relevant units. The shipment control

■ Quantities of recommended spare
parts
It is recommended as a rough guide to hold
in stock a certain quantity of parts according
to the rank (A, B, C, D, E) assigned to the
parts,as follows. For periodically replaced
pa r ts ,h o ld th e m in s t oc k s e pa r a t el y.
Adjust the stock quantity of service parts
depending on the number of working units
(N).
Quantity used in a single system : Q
○ N = 1
Rank A = 1 + Q × 0.3
Rank C = 1 + Q × 0.05
Rank D = 1 + Q × 0.02
○ 2 ≦ N ≦ 10
Rank A = 2 + N × Q × 0.3
Rank C = 2 + N × Q × 0.05
Rank D = 2 + N × Q × 0.02
○ 11 ≦ N ≦ 300
Rank A = 3 + N × Q × 0.3
Rank C = 3 + N × Q × 0.05
Rank D = 2 +
N × Q × 0.02
■ Precautions to be Observed When
Returning Parts in Need of Repair
When returning a component in need of
repair, pack it in the same manner as for the
supplied substitute, using the substitute
packing materials.
The use of different packing materials or
packing methods may incur damage to
packed component during transit.
