Datalogic Scanning 9504, 9500 manual Diagnostic Procedures, Operational Tests, Diagnostic Tests

Operational Tests

These are the tests that run continually during Normal Operation and Sleep Mode. Firmware checks all subsystems, accessory connections and the POS interface to verify everything is operating normally. If a problem is detected at any time, a long, low tone is sounded, an error code is shown on the 7-segment display, and operation may be halted. If you press the Volume/Tone Push Button at that time, a series of tones will be sounded that matches the error code displayed.

Diagnostic Tests

See Chapter 2, Diagnostic Modes, for details about running diagnostic tests for the scanner and/or scale. If a problem is discovered during diag- nostics, the scanner will provide feedback about the source of the prob- lem. The remainder of this chapter describes these failure indications and includes troubleshooting flowcharts to help isolate the problem.

Diagnostic Procedures

Your Point-Of-Sale (POS) system may contain many components that operate as a system. Since almost all scanner or scale problems are caused by either the scanner, scale, POS terminal or communication links between them, these troubleshooting flowcharts focus on these compo- nents. Additionally, the optional Remote Scale Display, AC/DC Power Supply and their cables are potential problems addressed in this chapter.

The flowcharts provided in this chapter walk you through a diagnostic process that will isolate the failed component and instruct as to the correc- tive action required. Since internal scanner and scale components cannot be replaced by an operator or installer, most functional errors will require the assistance of a trained technical support person. However, if the prob- lem is caused by faulty cable, power supply or remote display, you can fix the problem by replacing the defective component and complete the installation.
