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.

• 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.

The Lexmark C750 (5060-0xx) laser printer is available in two models:

• 5060-001

5060-002

The parts catalog uses these designations to identify model specific FRUs.
