Troubleshooting Process
The troubleshooting process is a systematic approach that addresses the
major problems first and then other problems as you identify the causes for
printer malfunctions and errors. The Troubleshooting Process, Figure 7-1,
on the following two pages, illustrates the major steps for troubleshooting
the printing system. Each heading depicts a major troubleshooting step. A
YES answer to the questions allows you to proceed to the next major step.
A NO answer indicates that additional testing is needed. Proceed to the
referenced location and follow the directions for that area. After completing
the additional testing, proceed to the next major step.
