Introduction
This section provides the Service Representative with Information pertaining to the organiza-
tion and use of this service documentation, and includes the following supportive reference
data:
Reference Symbology
Signal Nomenclature
DC Voltage Ranga Specifications
AC Voltage Range and Current Specifications
Section 1: Service Call Procedures (SCP)
This section is used by the Service Representative as a structured process for determining the
type and sequence of actions that are performed during a service call, the Service Call Proce-
dures section is designed to assist in the effective recognition of machine symptoms and prob-
lems, as well as to provide instructions for the maintenance and corrective actions that are
required to return the machine to the full operating condition.
Section 1 of this service documentation is the entry level for all service calls. The Service Rep-
resentative should begin each service call with the Initial Action procedure found in Section 1.
The Service Call Procedures section is composed of five integral elements: initial Action. Sys-
tem Checks, Subsystem Maintenance, Preventive Maintenance, and Final Action. The mainte-
nance and diagnostic activities in this section may direct the Service representative to perform
additional service activities found elsewhere in the documentation, such as RAPs, removal and
replacement procedures, and adjustment procedures.
The Initial Action procedure Identifies certain required actions that are necessary to obtain a
basic appraisal of machine operation at the start of the service call,
The System Checks subsection is used to test the machine in order to confirm and define the
problem areas. This subsection is used to assist the Service Representative in diagnosing the
not readily apparent machine problems, or when there are conflicting or ambiguous symptoms
present. It is important that this procedure be used in order to ensure that the correct symptom
is being diagnosed.
The Subsystem Maintenance subsection contains a specific activity procedure that must be
performed on the service call.
The Preventive Maintenance procedure contains a list of the cleaning and lubrication activ-
ities that are designed to extend and enhance the reliability and performance of the machine.
The Final Action subsection is used to identify the actions necessary to clear the call with the
Customer and to complete any administrative tasks that are associated with completing the
service activity.
Section 2; Status indicator RAPs
Section 2 of this documentation contains the Repair Analysis Procedures (RAPs) necessary to
repair all faults other than the image quality faults. The Service Representative will be referred
to this section from some other section of this documentation during the service call. When a
machine defect or fault has been resolved by using a RAP, the Service Representative should
Immediately return to the point in the service call from which section 2 was entered.
There are two types of RAPs found in section 2. The first type is a RAP that is associated with
the display of a status code or fault code in the RAP title. The second type is the Other Fault
RAP. Other Fault RAPs are diagnostic procedures that are designed to address symptoms or
problems that are not identified by, or associated with, a displayed status or fault code.
Section 3: Image Quality RAPs
This section contains the Image Quality Repair Analysis Procedures (IQ RAPs) that are used
to diagnose Image quality defect problems. The RAPs that are associated with Image quality
defect symptoms will contain the prefix "IQ" to differentiate them from other types of machine
failure symptoms.
Section 4: Repair and Adjustment Procedures
This section contains all repair and adjustment procedures for the machine. Repairs (REPs)
and adjustments (AOJa) are identified by the use of a standard chain prefix number.
Section 5: Parts List
This section contains a list of spare parts for the machine. All parts list page reference numbers
begin with the letters "PL", followed by a prefix number, a decimal point, and a sequential num-
ber used within the subsystem.
Section 6: General Procedures / information
This section contains procedures and Information of a general nature that apply to the
machine. This section Is divided Into two basic parts.: General Procedures and General Infor-
mation.
The General Procedures subsection contains frequently used procedures that relate to the
diagnosis, the setup, or the operation of the machine.
The General Information subsection contains product specific information that is pertinent to
the operation of the machine, but will not be found in any other part of the service documenta-
tion. This information may Include product codes, environmental operating data, installation
space requirements, and paper and electrical specifications. This subsection may also contain
information regarding supplemental tools and supplies, general service notes, a glossary of
commonly used terms, and a Change Tag Index of authorized machine modifications and ret-
rofits.
