Understanding The Troubleshooting Process - HP Color LaserJet 9500 Service Manual

Understanding the troubleshooting process

The troubleshooting process is a systematic approach that addresses the primary problems first,
and then other problems, to discover the causes for output device malfunctions and errors. The
troubleshooting flowchart on page 198 illustrates the primary steps for troubleshooting. An
answer to a troubleshooting question allows troubleshooting to proceed to the next primary step.
If an answer indicates that additional testing and correction is needed, proceed to the
appropriate section in this chapter and follow the directions there. After completing the additional
testing and correcting the problem, proceed to the next primary step.
Note Always follow this process in sequence. Failure to do so can result in increased repair time,
difficulty, and expense.
This list describes the basic questions to answer and provides the corresponding
troubleshooting sections that define the problem(s).
