Your black is looking a little hairy, too.

Was having the same issue with Cyan. It ended up being a smashed ink line where the lines joined in back (somebody over tightened).. Ink starvation.

yeah, your black looks kinda bad as gino pointed out.......looks like you have some issues with those heads!!

 

[ravitan]

Well the black is working like this for 18 months (no devil eye
I pulled a good amount of yellow from the pumps zone , no change so far..
Could it be air issu it strated when i run out of yellow then i the 6 lines missing it the test print(yellow)
Then i made fill up and look what happed
Is it true that fill up can help realease air from the system?
Anyway i saw u can realeas air frome the damper ,looks risky to me..

Could it be air issu, it strat when i run out of yellow in my bulk ink system then i got around 6 lines missing in the test print(yellow).

Then i made fill up ink and half of the yellow is missing
I want to pull some air from the system
Is it true that fill up can help realease air from the system?
Anyway i saw u can realeas air frome the damper area haw do i do that?

what could have happened is that your capping station screws hit the head. the blank center of the yellow indicated where the screw is pull the cover off the left side and slide the head over and take a peak. do you keep you head on thick or thin?

head strike I'd imagine. your head is fried.
take a peek underneath and you'll most likely fine a scratch across the center of the printhead.

You must not care what your output looks like from 5 feet away. Get new black heads. This is bad bad bad.

missing centers to test prints can be a clogged head manifold. do the missing lines move around? or is it the same pattern always?

As others have said look for a scratch under the head if it looks good could just be clogged. Your black head could be cleaned up and may recover some of those missing nozzles not sure since it been clogged for so long.

Here is what I would do if there is no scratch.
Do this to the black head as well may help recover the missing nozzles.

I have a JV3 and use triangle ink as well.
what I do when missing nozzles is remove the dampner and get a syringe full of flush move the carriage over and fold up a paper towel and set in on the wipper rails now push the carriage over until the head you are going to clean is over the paper towel now take the syring with a piece of tubing that fits the nipple the dampner goeas on (its the same size as the pump lines) put the tube on the nipple and push the flush through the head. I look under the head while doing this and apply enough pressure to get a stream (just enough pressure to get a stream) coming from the nozzles Iwill do this for at least 1 but usually 2 or 3 syringe fulls (I use a 3cc syringe I think its 3 cc) pull the paper towel out and replace after every syringe.

Put dampner back on and do ink fill.

This usually will clear up most of the nozzles if you do it as soon as the nozzles become clogged.

This works for me but I take no responsibility for any damage you cause.

on really bad heads I do the same thing but with an electric pump and I run the pump for 10 min or more with the head removed from the printer (with the pump setup you can see when the nozzles become unclogged and if they dont clear up after 3 or 4 10 min cycles they usually wont clear up). I had a head that looked worse than your black head and built this pump system and cleaned it and recovered the head to only 3 missing nozzles and have saved myself at least 3 heads since I built it.

Good luck
and if you do the syringe thing remember only enough pressure to get a steady stream coming from the nozzles.

On a side note Artbot is the man when it comes to the Mimaki printers I cant thank him enough for the help I have gotten from him. Thank You Artbot.

Final note:
I AM NOT RESPONSIBLE FOR ANY DAMAGE YOU MAY CAUSE USING THE METHOD I HAVE WRITTEN.

it looks like a scratch from the middel of the head to the left side
i wonder what made this one , since the scratch start in the middel and ends in the left side of the head (i print thick all the time) could not cose from the capping

could be the new wiper holder whith one arm longer .in the jpg its the one white no wiper in it. i got for free from the ink supplier

afther a weekend i saw the machin whith no wiper (which i found later..insid somewere..) the wiper released frome the holder
i dont know way.
the thec guy is on his way whith a new head (1050$ not includ work which i estimat around 200$ aawwochhhhhh)

thank u alll. thank u for the answers and support.

 

[SARTampaBay]

Ouch. Never seen a wiper holder like that. Oddly the mark on the head looks a little like a capping plate to me. Are those still in place?

 

[ravitan]

Yes they are
The tests r stedy blanks

you better beleive that i would be contacting that supplier and have a heart to heart ... atleast try to make a claim that he has to pay for it due to a faulty product...

while you have a tech coming in, i'd have him install the new printhead on the Black channel, and use the Black Head with the misfiring nozzles on the Yellow channel.

you'll still be limping on a mediocre printhead, but your alignments will be better (less banding) since the alignment procedures rely on the black printhead as the base for aligning the other printheads AND, who knows, the flush may improve those misfiring nozzles.

the techman was hear
he saw the scratch which thake place in 2 heads and replace bothe of them..
his said that it mite couse from the paper that sumtimies jammed or going up and toche the heads
