Once the print head has been inserted, the operator
console closed and the handset replaced, the fax ma-
chine starts the nozzle cleaning and checking procedure,
which is completed by:
• the printing, on the sheet loaded automatically, of a diag-
nostic 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 qual-
ity may be evaluated.
• the display shows the message: "CHECK PRINT OUT",
"1 = EXIT 0 = REPEAT".
Examine the print test sheet as follows:
1. Check that the numbered scale is not broken at any point
and that the black areas do not present any horizontal
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
initial stand-by mode
and is ready for use. The display shows

If, after the print head has been installed, the "CHECK

ing it and then reinserting it, pressing it more firmly into
position. If the message remains on the display, re-
move the print head and clean the electrical contacts
of the print head and the carriage, see "To clean the
electrical contacts of the print head", section
"Maintenance operations".
2. On the other hand, if there are any breaks or white lines
present, set 0 to clean the nozzles again: if the new print test
continues to be unsatisfactory, repeat the procedure another
time. At this point:
• if the printing quality still does not meet your expectations,
clean the electrical contacts and the nozzles as indicated in
the "To clean the electrical contacts of the print head"
section of the "Maintenance operations" chapter.
• if the printing quality is satisfactory, set the value 1. The
fax machine returns
