How To Use This Parts Catalog

•

SIMILAR ASSEMBLIES: If two assemblies contain a majority of
identical parts, they are shown on the same list. Common parts
are shown by one index number. Parts peculiar to one or the
other of the assemblies are listed separately and identified by
description.

• AR: (As Required) in the Units column indicates that the

quantity is not the same for all machines.

• CC: (Color Code) in the Description column indicates the part is

identified by a color marking on the part.

• NS: (Not Shown) in the Asm-Index column indicates that the

part is procurable but is not pictured in the illustration.

• PP: (Parts Packet) in the Description column indicates the part

is contained in a parts packet.

• INDENTURE: The indenture is marked by a series of dots

located before the parts description. The indenture indicates the
relationship of a part to the next higher assembly. For example:

INDENTURE RELATIONSHIP OF PARTS
(No dot) MAIN ASSEMBLY
(One dot) o Detail parts of a main assembly
(One dot) o Subassembly of the main assembly
(Two dot) o o Detail part of a one-dot subassembly
(Two dot) o o Subassembly of a one-dot subassembly

The Optra S laser printer is available in eleven models. The model
designations are as follows:

1250 (4059-121) 1255 (4059-125) 1620 (4059-162)
1625 (4059-165) 1650 (4059-160) 1855 (4059-185)
2420 (4059-242) 2450 (4059-240) 2455 (4059-245)
1855-C01 (4059-185) 3455 (4059-345)

The parts catalog uses the four digit model number to identify model
specific FRUs.
