Service Strategy
The service strategy of the DocuColor 12 copier/printer is to perform any High Frequency Ser-
vice Item (HFSI) actions before attempting to repair any problems. Some problems will be cor-
rected by this strategy without the need to diagnose them. The Repair Analysis Procedures
(RAPs) will be used for any remaining problems.
Problems that occur in the BASIC COPIER mode will be repaired before problems that occur
when using the accessories.
Image Quality problems will be repaired after all other problems are repaired.
Service Call Procedures
The Service Call Procedures are a guide for performing any service on the DocuColor 12
copier/printer. The procedures are designed to be used with the DocuColor 12 Service Manual.

Initial Actions
Purpose
The purpose of the Initial Action section of the Service Call Procedures is to determine the rea-
son for the service call and to identify and organize the actions which must be performed.
Procedure
1.
Gather the information about the service call and the condition of the copier/printer.
a.
Question the operator(s). Ask about the location of most recent paper jams. Ask
about the image quality and the copier/printer performance in general, including any
unusual sounds or other indications.
b.
Check that the power cords are in good condition, correctly plugged in the power
source, and free from any defects that would be a safety hazard. Ensure that the
connector for the IDFE Wiring Harness is properly connected. Repair or replace the
power cords as required. Check that the circuit breakers are not tripped.
c.
Inspect any rejected copies. Inquire as to, or otherwise determine, the paper quality
and weight. The specified paper for optimum image quality with the DocuColor 12
copier/printer is 24# Xerox COLOR Xpressions (NASG), or Colotech + 90 gsm
(ESG). Look for any damage to the copies, oil marks, image quality defects, or other
indications of a problem.
d.
Record the billing meter readings.
e.
Enter the Diagnostics Mode. Go to the
nostic Mode can not be entered. Return here after repairing the Diagnostics entry
problem.
NOTE: If a Fault Code is displayed while performing a Diagnostics Procedure, go to
that Fault Code RAP and repair the fault. Return to Diagnostics and continue with
the DC Procedure that you were performing.
f.
Go to DC135 HFSI Table and determine what HSFI action is required based on the
customer output volume. Refer to the
detailed HSFI information. Record any items that require action.
g.
Select the History File. Display and record the information in the Fail History, Jam
History, Fail Counter, and Jam Counter. Classify this information into categories:
Information that is related to the problem that caused the service call.
Information that is related to secondary problems.
Information that does not require action, such as a single occurrence of a prob-
lem.
h.
Check the Service Log for any recent activities that are related to the problem that
caused the service call or any secondary problem.
2.
Perform any required HSFI activities. Refer to the Detailed Maintenance Activities section.
3.
Exit diagnostics. Try to duplicate the problem by running the same type jobs, as the cus-
tomer was running.
4.
Check the image quality in the BASIC COPIER MODE. Select the tray that is loaded with
11 X 17 or A3 paper. If unable to complete this step, go to step 5.
