Problem Isolation

In the event of a suspected functional problem, use the troubleshooting references provided in this section. This useful information will help you to identify and resolve the cause of the problem.

The scanner/scale has a number of features that indicate when a scanner or scale problem occurs. The unit may:

•emit a series of tones•light the 7-segment (FRU status) display•flash the Green and/or Yellow LEDs•display error codes on the Remote Display (if installed)

Three error reporting modes are used: Power-Up Selftest, Operational tests and Diagnostic tests. These test sequences are explained on the following pages.

Power-Up Selftest

The Power-up Selftest is a pre-operational series of tests that must be successfully completed before the scanner indicates readiness for operation. This pre-operational period is the time between power-up and normal operation during which the motor comes up-to-speed and software, firmware and hardware are being tested. These tests ensure that all subsystems are fully functional before turning on the Visible Laser Diode (VLD). Refer to the Section 3 subsection titled, Operational Modes for a more detailed description of this and other scanner and scale modes.

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.
