Problem Isolation
The troubleshooting references provided in this section should be used in the
event of a suspected functional problem. This information will assist you in
identifying and resolving any problems.
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 Health & Status Indicator (FRU status) display
• flash its indicator 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 success-
fully completed before the scanner indicates readiness for operation. This pre-
operational period is the time between power-up and normal operation during
which the software, firmware and hardware are being tested. These tests
ensure that all subsystems are fully functional before turning on. Refer to
Operation and Maintenance on page 49 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 Health &
Status Indicator, and operation may be halted. If you press the Scanner Control
Button at that time, a series of tones will be sounded that matches the error
code displayed.
