Chapter 4. Problem Isolation; Operational Tests - Datalogic Magellan 2200VS Reference Manual

Product Reference Guide
Problem Isolation
In the event of a suspected functional problem, use the troubleshooting
references provided in this section. This useful information will help you
identify and resolve the cause of the problem.
The scanner incorporates features that indicate when a problem occurs.
The scanner may:
• emit a series of tones
• flash the LED (lamp)
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
Chapter 3, Operational Modes
of this and other scanner modes.

Operational Tests

These are the tests that run continually during Normal Operation and
Sleep Mode. Firmware checks all subsystems, accessory connections as
well as the POS interface to verify everything is operating normally. If a
problem is detected at any time, a long, low tone is sounded and operation
may be halted. If you press the Volume/Tone Push Button at that time, a
series of tones will be sounded in concert with LED flashes.
