Product Reference Guide 4-1
Section 4
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 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 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.
