HAT HAPPENS IF THERE IS A POWER FAILURE
If there is a power failure, the fax machine keeps the follow-
ing data in the memory: the numbers set for one-touch
and speed dialling and the reports, while the documents
present in the memory will be lost.
The date and time will also be lost so they will have to be
reset by carrying out the procedure described in the "To set
the date and time" section of the "Operations essential
for correct operation" chapter.
W
HAT HAPPENS IF THE PAPER OR INK HAS
RUN OUT
If, during reception, the paper runs out or gets jammed,
the ink runs out, the print head compartment cover
is open, the paper support is closed or the operator
console is raised, the machine stops printing and the
display shows the relevant message and the document you
are receiving is temporarily recorded in the memory.
Once the problem has been solved, the fax machine
resumes printing.
I
F THE TRANSMISSION IS UNSUCCESSFUL
Sometimes, due to line problems such as excessively heavy
telephone traffic or any other kind of interference, the docu-
ment sent is received badly by the correspondent, who will
ask you to send it to him again.
In these cases, it is advisable to send the document again at
a slower speed. The fax machine transmits regularly at a
speed of 14400 bps (bits per second). To reduce the speed,
follow the procedure described in the "To reduce the trans-
mission speed" section of the "More sophisticated op-
erations" chapter.
If transmission is not completed due to errors on the line
or fax machine, the error LED "
" lights up and a short
beep is emitted; in this case, the fax machine automatically
prints the transmission report (see "To print reports
and lists", chapter "Basic transmission and reception
operations"), on which an error code indicates the cause
of the error (you will find a list of all the error codes later).
F
OR MINOR PROBLEMS
The list below may be used as a guide to the solution of minor prob-
lems.
PROBLEM SOLUTION
The fax machine gives no
sign of life.
Check that it is connected to
the power socket.
The document is not fed in
correctly.
Check that the document
respects the
recommendations listed in
"
What documents may be
used", chapter "Basic
transmission and reception
operations".
The fax machine will not
send a document.
Check that the document is
not jammed.
The line is busy: wait until it
is free and then try sending
the document again.
The fax machine will not
receive a document
automatically.
It is set for manual
reception: set it up for
automatic reception.
The fax machine will not
copy or receive documents.
Check that no documents or
sheets of paper are
jammed.
You are using an unsuitable
kind of paper: check the
characteristics of the paper
listed in the "
Technical
data".
The fax machine prints blank
sheets.
Place the document in the
correct position with the
side to be copied facing
upwards.
NOTe
Incorrect transmission or reception by the fax machine may
also depend on factors other than those listed above, which
will be signalled in the form of error codes on the "Trans-
mission report" and "Activity report", see "To print re-
ports and lists", chapter "Basic transmission and re-
ception operations".
