UTOMATIC
HEAD
NOZZLE
CLEANING
AND
TESTING
PROCEDURE
Once the print head has been inserted
, the fax machine starts
the
nozzle cleaning and checking procedure
, which is com-
pleted by:
the
printing
, on the sheet loaded automatically, of a diagnostic
test sheet containing:
-a
numbered scale
, for checking the flow of ink and the
electrical circuits of the print head nozzles.
-a group of
graphics and text
, so that the printing quality
may be evaluated.
the display shows the message: "CHECK PRINT OUT",
"1 = EXIT 0 = REPEAT".
Examine the print test sheet as follows:
Check that the numbered scale
is not interrupted at any
point
and that the black areas
do not
present any horizon-
tal white lines
: if these conditions, which confirm that the print
head has been inserted correctly and is working properly, are
respected, set the value
1
. The fax machine returns to its initial
stand-by status and is ready for use. The display shows the
message:
AUTOMATIC RX 00

On the other hand, if there are any
interruptions or white
lines
present, set

to clean the nozzles again: if the new print
test continues to be unsatisfactory, repeat the procedure an-
other time. Then, if the printing quality does still not meet your
expectations, clean the electrical contacts and the nozzles as
indicated in "

head
" and "

P
RECAUTIONS
ABOUT
THE
USE
OF
HEADS
For
base models
you can
only
use
monochrome print heads
(black), whereas for
multifunctional models
you can use
mono-
chrome
or
colour print heads
. Howewer, remember that in both
cases you can
only
use
single-block print heads
(
non recharge-
able
).
Monochrome
, for use with the
facsimile
,
or the
printer
in
black
and white
mode.
Colour
, for use with the
printer
in
colour
mode.
notE
For multifunctional models only
When the colour print head is installed, the documents re-
ceived will
not be printed straight away
, but stored in the
memory of the facsimile machine. Once the memory is full, the
facsimile will no longer be able to receive documents, so
always remember
to replace the monochrome print head
each time the facsimile is reset.
