Troubleshooting
(7)
With a clean stick R, clean the nozzle surface of print head.
<IMPORTANT>
Be sure not to bring corner edges of the clean stick R into contact with the nozzle surface.
Avoid roughly rubbing the nozzle surface.
The used clean stick R should be disposed of, and should not be reused.
(8)
Close the right-side cover and press
in response to the instructions on the screen.
<NOTE>
Dispose of any waste resulting from the cleaning in accordance with applicable laws and ordinances.
<TIPS>
Because the cleaning cup will be reused, rinse it in clean cleaning solution and store it in a safe place.
(9)
Print out a nozzle check pattern.
(10)
Check a result of the resultant nozzle check patterns, and carry out the following procedures.
Existence or nonexistence of a
nozzle that does not eject any
ink-jet droplets
Recovery action
Such a nozzle does not exist that
does not eject any ink-jet droplets
Exit
Such a nozzle exists that does not
eject any ink-jet droplets
Proceed to Step 5.
<IMPORTANT>
Even if the nozzles on the white side have a bit of problem concerning firing, since the white ink is ejected on one same
spot through multiple nozzles, relatively large amount of ink volume will be used, and firing problem of a single nozzle will
not affect the print quality so much. Even in a condition with a problem concerning firing as shown in (a), print is performed
without a problem as shown in (b).
