Troubleshooting process The troubleshooting process is a systematic approach that addresses the primary problems first, and then other problems, to discover the causes for MFP malfunctions and errors. An answer to a troubleshooting question allows troubleshooting to proceed to the next primary step. Certain answers indicate that additional testing and correction is needed. Proceed to the appropriate section in this chapter and follow the directions. After completing the additional testing and correcting the problem, proceed to the next primary step. This table describes the basic questions to answer and provides the corresponding troubleshooting sections that define the problem(s). Table 21.
