NSERT THE PRINT HEAD
I M P O R T A N T
Once the print head provided with the machine is worn, re-
m e m b e r
o n l y t o u s e o r i g i n a l p r i n t h e a d s ( s e e c o d e
printed at the end of the manual ).
If, after the print head has been installed, the "CHECK PRINT
HEAD" message appears again, try removing it and then
reinserting it, pressing it more firmly into position. If the mes-
sage remains on the display, remove 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 ", sec-
tion " Maintenance operations ".
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 diagnos-
tic 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:
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:
AUTOMATIC 00
25-03-04 11:23
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.
