5. DIAGNOSTICS
5.1 SELF-DIAGNOSTICS
The facsimile machine automatically runs a diagnostic program (SELF-
DIAGNOSTIC TEST) the first time it is powered on and on reactivation after a power
failure or disconnection from the mains:
- if the self-diagnostic test is passed , the facsimile machine enters standby
m o d e
- If instead the self-diagnostic test is failed , the fax machine shows an error code
on the display (SYSTEM ERROR xx). In this case, the fax machine needs to be
disconnected from the power supply socket before eliminating the related
problem.
The self-diagnostic routine tests the following components:
•
EPROM
•
static RAM
•
printer.
