SCP 3 Normal Call Actions
Normal Call Actions are used to determine the reason for the service call.
SCP 4 Fault Analysis
Fault Analysis is used to identify a fault.
Procedure
NOTE: If a fault message appears at any time. Refer directly to the RAP for the fault message
and perform the procedure.
If possible, perform the following:
1.Review any defective print samples.
2.Determine that the user accessible settings are correct. If necessary refer to the user documentation.
3.Check all job queues and verify with the customer any requirement to print the documents
in memory, before switching off the power or clearing memory.
4.Print the Customer Assistance Report (Call for Assistance), then record the total print
count.
5.Go to SCP 4 Fault Analysis.
Procedure
When diagnosing or repairing a fault in a particular subsystem, exercise the machine in all
modes until the fault is determined. In the instance of finding more than one fault or failure, cor
rect one fault before going to the next fault. If no fault is found, go to SCP 5 Subsystem Maintenance.
Fault Codes
If a fault code is displayed, go to the relevant RAP.
Control Panel Faults
If the power is on but the Control Panel is blank, test the Control Panel with dC330.
Stapler Faults
If the machine has a stapler fault, test the Stapler with dC330.
Image Quality Defects
If the image quality is defective, go to the IQ1 Image Quality Entry RAP.
For image quality specifications, refer to the following:
•IQS 1 Solid Area Density.
•IQS 2 Skew.
•IQS 3 Registration.

SCP 5 Subsystem Maintenance
Subsystem Maintenance contains information regarding the component life of the machine.
Procedure
WARNING
Switch off the electricity to the machine. Di sconnect the power cord from th e customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury . Moving parts can cause injury.
1.Clean the Pick Rollers on every call.
2.Use the Control Panel to check maintenance item counters.
3.Compare the counter values to those listed in Component Life.
4.Advise the customer of any routine maintenance items that are approaching or over the
service limit.
Inspection
Rollers
Replace rollers when you see any of the following defects:
•Flat spots
•Out of roundness
•Cracked rubber
•Loss of traction (tackiness) causing pick or feed failures
Gears
Replace gears that show any signs of wear or damage. Look for these problems:
•Thinned gear teeth
•Bent or missing gear teeth; check especially where a metal gear drives a plastic gear.
•Fractured or cracked gears (oil or incorrect grease on a plastic gear can cause the gear to
crack).
Lubrication
The printer is lubricated during assembly at the factory and does not require periodic lubrication. Some parts require lubrication following replacement. These parts are identified in the
replacement procedures. When lubricating during replacement, use approved grease.
Service Call Procedures
SCP 4, SCP 5
CAUTION
Plastic parts deteriorate when unspecified lubricants or chemicals are used. To avoid damage,
use only Rheolube 768 grease.
•Rheolube 768 Grease: Part Number 070E00890

SCP 6 Final Actions
Final Actions are used to evaluate the total operation of the system and to identify the actions
required to complete the service call.
Procedure
Complete the following, if a fault is identified, return to SCP 4 Fault Analysis:
•Perform the end of call subsystem maintenance actions, SCP 5 Subsystem Maintenance.
•Exercise the machine in all modes, printing from all trays. If a fault message is displayed
or some other problem is evident, go to SCP 4 Fault Analysis.
•Make a print of a customer document.
•If any of the customers selections were changed, return t hem to the cu stomers preferred
settings. Refer to GP 3 Customer Administration Tools.
•At the first service and at any subsequent service where changes are made or options are
added, print the configuration report and store it with machine log book. Discard any pre
vious versions of the configuration report.
•Remove and destroy any copies of test patterns.
•Ensure the machine and service area are clean before leaving the customer premises.
•Provide customer training if required.
