Service Diagnostics
The Phaser 7100 printer has built-in diagnostics to test electromechanical components, display status,
and provide some NVRAM access. Use these tests to diagnose problems and isolate which component
or sub assembly part needs replacement.
If confronted with an error that requires more than a cursory investigation to clear or when directed by
a troubleshooting procedure, use Service Diagnostics to exercise selected sub-assemblies of parts in the
vicinity of the reported error. Diagnostic tests are controlled from the Control Panel and are described
in this chapter.
