Troubleshooting
Step 1: Print out a nozzle check pattern
(5)
Print out a nozzle check pattern (1st time).
☞
"6-1-17. Print out the nozzle check pattern (checking on the print
heads) >>P.6-44"
(6)
Check the result of the printed nozzle check pattern (1st time), and carry out the following procedures.
☞
"6-1-17.
Print out the nozzle check pattern (checking on the print heads) >>P.6-44"
<TIPS>
Even if the white print result is weak, since the white ink is ejected on one same spot through multiple nozzles, a relatively
large amount of ink volume will be used, and the firing problem of a single nozzle will not affect the print quality so much.
Even in a condition with weak lines, the print is performed without a problem.
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
Contact your dealer if there is no non-ejection when printing the nozzle
check pattern, but a large amount of non-ejection occurs during printing.
Such a nozzle exists that does not
eject any ink-jet droplets
Proceed to Step 2.
Step 2: Perform the head cleaning
(1)
Perform a normal cleaning.
☞
"6-1-15. Head cleaning >>P.6-41"
(2)
Print out a nozzle check pattern (2nd time).
(3)
Check the result of the printed nozzle check pattern (2nd time), 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
Ten-or-less nozzles exist that do
not eject any ink-jet droplets
Perform the normal cleaning once again. Subsequently, proceed to (4).
Ten-or-more nozzles exist that do
not eject any ink-jet droplets
Perform the powerful cleaning. Subsequently, proceed to (4).
More than half of the nozzles do
not eject any ink-jet droplets
Perform air bleeding in the tube. From the menu, select [Maintenance] >
[Tube air bleed] and select the corresponding head and color.
(4)
Print out a nozzle check pattern (3rd time).
(5)
Check the result of the printed nozzle check pattern (3rd time), 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 3.
