Troubleshooting System Error Codes
Chapter 2 - System Error Codes contains a list of system error
codes and their respective descriptions and recommended corrective
actions. Only try one recommended action at a time and check if the
error code has disappeared.
Performing a Service Test on a Failed Assembly
If possible, always perform a Service Test on the component/
assembly that you are about to replace, just to make sure that is the
component/assembly that has failed.
NOTE If the test on that component/assembly passes, you should NOT
replace it.
For information on the Service Tests and how to use them see
Chapter 4 - Service Tests and Utilities.
Performing the Necessary Service Calibrations
Is the printer calibrated correctly after replacing a component?
NOTE Remember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.
For information on the Service Calibrations and how to use them
see Chapter 5 - Service Calibrations.
