the test three times, the print nozzles are clean.
• If the print quality of both lines is still not satisfactory,
wipe the print cartridge nozzles. For help, see the next
section.
Broken lines at
the top of the
page indicate

Unbroken lines at
the bottom of the

these colors
do not print,
you may need
to replace
your print
cartridge.
