About This Manual
Introduction
About This Manual
This manual is part of a multinational service documentation system that is structured in the
standard Xerox service manual format.
This manual is based on a Korean original. The part names used throughout do not comply
with the standard Xerox part naming convention. Because part names have been molded on to
some plastic components and may also be embedded in the software, the part names have not
been changed.
To aid part identification, an acronym list and cross reference lists of more commonly recogn-
ised part names have been included in the manual. Refer to GP 20, Acronyms and Parts
Description List.
