Thank you, I am going to clean all system, and I am waiting for new pump(white ink) which seems weak and sometimes works sometimes not too much. 

Thank you very much for your help.

So far I tried:

- changed head

- changed dampers

- changed filter in white circulation system.

- change ink, material just in case

- turned off white ink circulation

- changed white container (which has stirring)

The nozzle is not perfect even with new head, but it seems that for this particular problem it doesn't matter, sometimes the nozzlecheck is better but the problem is worse and vice versa - but I understand that there has to be some problem if the nozzle is not ok with new head.

The machine is about 7 months old and it was always running with no problems.

What I have not tried yet, is clean white tubes and change the feeder tank which is right before the dampers - could this help ? Should I do this ? And if yes how often ?

But, the problem is not constantly same, for example yesterday, in the morning it was almost good, just small amount of dots around, then it got much worse with a lot of dots, I tried one strong cleaning and one normal cleaning right after the strong one and then suddenly it was perfect 100% clean for the rest of the day, several hours of printing. Today almost perfect but not as yesterday, tried the same cleanings but it doesn't do much difference.

What do you meen keep it off, turn off the white ink circulation ? Why do you think it could be causing this problem ?

I have changed the ink tank in December and dampers last weekend. 

Do you think that cleaning ink tubes could help ? The machine is like 6 months old.

Also, it is getting lot better after like 2-3 hours of printing, then cleaning and it is almost ok. Maybe some enviromental issue ? 

I have double XP600 DTF printer, and have this problem now.

- white ink like sprinkles and creates a lot of little dots around the print, it gets even under the metal holding plates as you can see on the foto.

- they have changed dumpers, head and filter but still have this problem.

- the nozzle is almost perfect but not 100% perfect even with new head

- right after cleaning it is almost ok then it is getting worse while printing.

Hello,

has anybody tried this roll printing software ? ZiggRoll - https://dtgdtf.com/zig-roll-sp-roll/

It has some nice functions, but I can't find much info, only from the seller.

I did not go that route. I’m still using my p800’s. The p5000 technically should be twice as fast as the p800, or 24 sq ft an hour plus two additional spot color/spare channels. BUT I haven’t bought one to try, $1800 is a lot. 

I tried to get p800 but no success and p900 is not supported yet so am just trying to find something good to replace my L1800, I print like 10-12 hours a day and I want to replace it with something faster. Maybe I'll just wait who comes first with support for p900 and I get that. I use AcroRIP now, but anyway I would have to buy new one.

now I see sorry...

I am still undecided between P900 and now P5000   Have you bought P5000 already ? Is it dificult to convert it for DTF ?

Cadlink now supports it, so I’m not stuck with acro rip 10.X to use it. ( which acro doesn’t officially support it anyway). 

I have asked Cadlink today and they told me, that there is no support for P900 DTF yet, you have tried it ?
