Composition of the service manual
This service manual consists of Theory of Operation section and Field Service section to
explain the main machine and its corresponding options.
Theory of Operation section gives, as inform ation for the CE to get a full understanding of
the product, a rough outline of the object and role of each function, the relationship
between the electrical system and the mechan ical system, and the timing of operation of
each part.
Field Service section gives, as information required by the CE at the site (or at the cus-
tomer’s premise), a rough outline of the se rvice schedule and its details, maintenance
steps, the object and role of each adjustment, error codes and supplementary information.
The basic configuration of each section is as follows. However some options may not be
applied to the following configuration.


OUTLINE: Explanation of system configuration,
product specifications, unit configuration, and paper path
COMPOSITION/OPERATION: Explanation of configuration of each unit,
operating system, and control system
OUTLINE: Explanation of system configuration, and product
specifications
MAINTENANCE: Explanation of service schedule, maintenance steps, ser-
vice tools, removal/reinstallation methods of major parts,
and firmware version up method etc.
ADJUSTMENT/SETTING: Explanation of utility mode, service mode, and mechanical
adjustment etc.
TROUBLESHOOTING: Explanation of lists of jam codes and error codes, and
their countermeasures etc.
APPENDIX: Parts layout drawings, connector layout drawings, timing
chart, overall layout drawing are attached.
