Once the print head has been inserted , the operator
console closed and the handset replaced , the fax ma-
chine shows the message: "NEW PRINT HEAD?", "1 = YES,
0 = NO". Set the value
1 ; the fax machine 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
to its
initial stand-by mode
and is ready for use. The display shows
the message:

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 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 to its initial stand-by mode and is
ready for use.
