Introduction - Fuji Xerox DocuCentre SC2020 Service Manual

4.1 Introduction

This section contains procedures required for parts disassembly,
assembly, replacement and adjustment in the field service.
4.1.1 How to Use the Disassembly/Assembly and
Adjustment
1. For installation procedures, only NOTEs are described here
since installation procedures are the reverse of removal ones.
2. (Figure X) at the beginning of a procedure indicates that its
detailed steps are shown in illustration. Numbers in the illustra-
tion indicate the sequence of the steps.
3. (REP X.X.X) at the end of a procedure indicates the replace-
ment procedure to be referred to.
4. Item numbers of disassembly/assembly and adjustment proce-
dures (i.e. REP/ADJ No.) correlate to PL No. in Chapter 5 Parts
List. Therefore, an appropriate replacement or adjustment pro-
cedure can easily be referred to a PL No. or vice versa. E.g.
The replacement or adjustment procedure of Component PL
1.1 is REP 1.1.X or ADJ 1.1.X.
5. When replacement/adjustment procedures or title items vary
by modification or model, the modification number or the model
are indicated at the beginning or the end of the respective titles
or procedures.
E.g. 1) REP X.X.X Main PWB [Models with 1V]
*Indicates that the entire procedure under this title applies
to machines with Tag 1V.
E.g. 2)
