Datalogic Scanning 9500, 9504 manual Problem Isolation, Power-Up Selftest

Chapter 4 Problem Isolation

In the event of a suspected functional problem, use the troubleshooting references provided in this chapter. 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, EAS deactivation system, or scale problem occurs. The unit may:

•emit a series of tones

•light the 7-segment (FRU status) display

•flash one or more 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 fol- lowing pages.

Power-Up Selftest

The Power-up Selftest is a pre-operational series of tests that must be suc- cessfully 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, firm- ware 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 Chapter 3 subsection titled, Operational Modes for a more detailed description of this and other scanner and scale modes.
