5.1.1 Description of the Self-Diagnostic Program
Diagnostic step
Error message
1) The facsimile machine is pow-
ered on: the error LED lights up
2) The EPROM is tested
3) The static RAM is tested
4) Printer startup: check that the
print carriage is reset.
5) The paper edge sensor is tested.
6) Self-diagnostic program ended
successfully: error LED switches
off.
(1) To solve this problem, replace the EPROM.
(2) This error means that the data of the static memory have been damaged, so U.K./
S. AFRICA country software parameters have automatically been loaded. To solve
this problem, proceed as follows:
- disconnect and reconnect the fax machine from the power supply socket: if the
error message persists, replace first the rechargeable battery then, if the error
still persists, replace the motherboard. If instead the message disappears,
proceed as follows:
- perform LOAD DEFAULT (see sect. 6.1.7), ALIGNMENT TEST (see sect. 6.1.1)
and SCANNER SHADING (see sect. 6.1.8) procedures
- perform fax machine nationalisation and reset installation and configuration
parameters (see sect. 3.2).

motor (replace the defective part: motor, belt, etc.).
4) This problem could be caused by the absence of the carriage limit stop plate (right
