UTOMATIC PRINT 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 numeric scale is not interrupted at any point ,
that the black areas do not present any horizontal white
lines : and that the vertical lines are perfectly aligned : in
these conditions, which confirm that the print head has been
inserted correctly and is working properly, set the value
1. The
display shows the message "ALIGNMENT:ON". Press the
key to exit from the procedure and return the fax ma-
chine to its initial stand-by mode.
• On the other hand, if there are any interruptions or white
lines present, set 0 to clean the nozzles again: if the new print
test continues to be unsatisfactory, repeat the procedure an-
other time.
