④Total non-ejection of the upper and lower halves of a line
Faulty head/replace.
③Total non-ejection of
two adjacent colors
Suspect a fault in the
recovery system, ink
supply system or head
Suspect a fault in the
electrical system
Not a faulty power PCB
Yes
No
Is there a history of occurrences
of Vh monitor error 2618?
T11
T17
Possibly faulty ink supply
system
Possibly electrical
non-ejection in any part
other than the head
⑤Regularly ordered
non-ejection
T17
Suspect a fault in the
electrical system
Not a faulty power PCB
Perform Cleaning B
Changing or diminishing
positions (non-ejection
corrected)
Positions unchanged or increased (*)
(non-ejection persisting)
T17
Electrical non-ejection most
likely in any part other than
the head
Electrical non-ejection most
likely in any part other than
the head
* The nozzles may have failed by themselves, Replace the head,
after performing T17 to make sure that there are no electrical
faults elsewhere.
⑥Data missing non-ejection (in
line A or B only)
T17
Suspect a fault in the
electrical system
Not a faulty power PCB
Possibly electrical non-ejection in any part other
than the head
⑦Data missing non-ejection (in
both lines A and B)
T17
Suspect a fault in the
head
Most unlikely flat cable breaking
⑧Mixed colors
⑨Blurring
T11
Problem persists after
Cleaning B
Suspect a fault in the
recovery system, ink
supply system, waste
ink route or head
Possibly faulty ink
supply system
⑩Non-ejection of all
colors in one or two
