2. Diagnostic Information The diagnostic information in this chapter leads you to the failing part. Before you replace an entire assembly, determine if just the defective part is available in the parts catalog. Some diagnostic procedures indicate the parts catalog location of the part to be checked by including the assembly number and reference number in parenthesis. Some part numbers are also included. Use the error code tables, symptom table, service checks and the diagnostic aids chapter to determine the symptom and repair the failure. After you complete the repair, perform the appropriate tests to verify the repair. If an error is displayed, locate it in the following Operator Error Message Table, or the Service Error Message Table and take the appropriate action. If an error message appears while you are working on the machine, go to the error message table and take the indicated action. Use the Locations chapter to find connector, board, and pin information. The sequence given in the service check is connector, board, and pin. The board uses only a letter for an identifier. For example, connector CN8A-3; CN8 = connector, A = board, -3 = the pin. Start Initial Check Before you start troubleshooting, check the following: Installation Environment The power supply line voltage is plus or minus 10% of the rated line voltage. The machine is securely installed on a level surface in a wellventilated place. The room temperature is between 10 and 32°C (50 and 90°F) and the relative humidity between 20 and 80%. Avoid sites generating ammonia gas, high temperature or high humidity (near water faucets, kettles, humidifiers), cold spaces, near open flames, and dusty areas. Diagnostic Information 2-1
