PRECAUTIONS
Since you will have to change the print head at fairly
regular intervals that will vary depending on how
intensively the machine is used, the following
precautions should also be observed:
•
do not attempt to refill the print head: this could
damage the head itself or the machine.
•
keep print head not in use in a suitable holder
(not included with the machine). This will ensure
longer print head efficiency and higher print
quality.
•
take care not to get ink on yourself: ink stains
are difficult to remove.
The machine automatically recognises the type of
print head installed and checks the ink level using
a specific internal counter so as to display the “OUT
OF INK” message when necessary.
To ensure that the ink level counted by the machine
coincides with the actual level in the print head, never
use print heads taken from other (fax or printer)
machines. When inserting a new print head, you must
indicate to the machine that the print head you have
inserted is new (see previous paragraph).
PRINT HEAD CLEANING AND NOZZLE
TESTING ...
If the printing quality deteriorates, you can clean the
print head and test the nozzles with a printout showing
their condition.

6.
Press the START key. The fax machine will
automatically begin cleaning the print head and
cleaning and checking the nozzles. It will print the
result of this check (PRINT TEST) on a sheet
inserted automatically from the ASF. The display
will alternate the following messages:

PLEASE WAIT
PRINT TEST
PLEASE WAIT
On completing the print test, the machine returns
to the initial waiting mode.
7.
Check the print test for gaps in the lines between
one nozzle and another. A broken line indicates
that the corresponding nozzles are blocked.
If this is the case, try re-cleaning the nozzles. If the
new print test also proves unsatisfactory, repeat the
entire procedure again.
