1.2 About Flowcharts
The Sun Blade 1500 Service, Diagnostics, and Troubleshooting Manual contains
flowcharts that you can use to:
■ Determine how to use this book.
■ Identify workstation malfunctions.
■ Verify workstation operation after completing the service procedure.
Each flowchart begins with a problem statement and a description of normal
operation.
Flowcharts use structural elements, as described in TABLE 1-2:
