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 page 378 and figure 7-2 on page 379, illustrates the major steps for troubleshooting the printing system. Each heading depicts a major troubleshooting step.
