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.
