5.1
SELF-DIAGNOSTICS
The facsimile machine
automatically runs a diagnostic program
(SELF-DIAG-
NOSTIC 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 mode
-
if the self-diagnostic test is
failed
as a result of a
correctable error
, the facsimile
machine displays an
error code
on the display.
If this occurs, you must always
replace the motherboard
, unless a keyboard
error occurs (in this case you must replace the console board or the flat cable that
connects it to the motherboard).
The self-diagnostic routine tests the following components:
•
EPROM
•
keyboard
•
printer.
The self-diagnostic test stops at the first test in which a fault is detected.
