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
subsection titled,
detailed description of this and other scanner and scale modes.
