JV3 130SP2 half black missing on test draw

Could be empty ink lines, so you may want to check that the dampers are full, but
when it happened to us, it was the slider board.

[Bob Scullion]

Thanks for the reply Jamie, excuse my lack of knowledge, the dampers, is that where the ink is stored before being sent to the head, where people mention drawing it through with a syringe?

Whats the slider board?

Thanks again

Bob

[Jamie Wood]

The dampers are the little plastic reservoirs which sit above the heads in the head
assembly, and the slider board is a circuit board which also lives in the head assembly.
Unfortunately, I don’t know of any way to check the slider without an engineer visit.
May be worth contacting Stafford, as he’s a Mimaki guy.

Thanks again

we had a simpler problem with ours, after hours of cleaning and no joy, we called the tech.

Turned out, that the thing the head sits on is held on by 2 screws, and sometimes these screws hit the head and kill it.

This happen to ours, the tech guy counter sunk the screws so hopefully it won`t happen again.

[Bob Scullion]

Denise do you have a name and number for your tech guy just in case.

Thanks

[John Thomson]

I have had this in the past………run an ink fill or pull ink through with a syringe…….hopefully it is not the slider board.

Thanks very much Mr Thomson, how you doing? long time no see (I think I still owe you a tenner or so) 🙂

[Bob Scullion]

Can anyone suggest why the printer would use more ink (black) than normal, I put 2 new cartridges in approx 2 – 3 weeks ago and although I’ve printed a fair bit the black is now registering 1 for each cartridge.

I am sure I had not used anywhere near 2 cartridges worth of black ink in that time.

Could this have anything to do with the waste ink bottle overflowing?

Thanks

[Bob Scullion]

Ive just tied to work out how much black ink ive used (Onyx rip software shows approximately how much of each ink has been used per print) and by my calculation i have used around 50ml but have only a very small amount left in each black cartridge, reading 1 in each cartridge of 440ml each !

Any Ideas?

Bob, where are u based, our guy is between Manchester and stoke on Trent.

For over usage of ink,check the automatic head clean time, I mentioned our ink overflow bottle thingy, needed emptying a lot more than the other mimaki, it was on clean ever 4 hrs…. Changed it to every 24hrs, should save on in know.

[John Thomson]

if the waste bottle overflowed that may have siphoned ink from the carts?

john

[Bob Scullion]

Thanks John, thats what I thought, something along those lines, but why only the black? and could this in some way be part of the reason half the blacks not printing, if the cart is empty could there be a fault with the chip reader on the machine in that it has failed to indicate no ink but in actual fact is indicating near end!!

I checked in greater detail last night and tried to calculate how much black has been used since replacing both blacks (21st May) approx 70 to 75 ml according to the print software.

2 new cartridges due in today so hopefully will get things sorted.

Thanks for the replies guys

Im in Glasgow Dennise, my machine is set to 24 hours for sleep and routine clean, as John suggested its possible that with the waste bottle overflowing it has somehow caused a syphoning effect with the black, which would explain the usage issue.

Thanks again for taking the time to reply

the length of the pipes from the pumps might be different…….if the black is longer it would be the first to siphon…….

Hope it is as simple as that for you.

John

[Bob Scullion]

Hope so too, thanks again for the reply

[Bob Scullion]

Just to say thanks to those who replied to my post, got it sorted (well test draw anyway) looks like you were right John regarding the syphoning effect with the waste bottle overflowing.

Fitted new cartridges, done an ink fill, nozzle wash and draw through the ink at the pump and test draw fine.

Thanks again guys, much appreciated.
