Carlos4072 Posted May 5, 2022 Share Posted May 5, 2022 Hi guys, do you have any clue about this issue ?? All my prints have a strange patter every 2.5cm and this patter is 1cm of height. All my nozzle test are perfect, no problems of clogs. I using just 2 wihte channels and saving the other 2 for later. I already cleaned the encoder, encoder reader, printhead surface, manifold, replaced dampers, and double check every connection. The printer worked flawless for about 1 year, but now start to do this (please check the attached pictures): Quote Link to comment Share on other sites More sharing options...

johnson4 Posted May 5, 2022 Share Posted May 5, 2022 If you print a big block, say 10x10 of solid magenta, what happens? Quote Link to comment Share on other sites More sharing options...
Carlos4072 Posted May 5, 2022 Author Share Posted May 5, 2022 Im using Acro 9 and 10, but this happen also using photoshop for example. Yellow also have this issue, but is hard to see in the photos. Just black and white not show this "noise" or "static". Quote Link to comment Share on other sites More sharing options...
anum11 Posted May 6, 2022 Share Posted May 6, 2022 Could be pet film issue, did you check it with paper? Quote Link to comment Share on other sites More sharing options...

Yellow also have this issue, but is hard to see in the photos. Just black and white not show this "noise" or "static". This is what mine looks like when my printhead is either missing nozzles, or head going bad- or you are using bad ink- bad cartridge. For me, using some expired magenta in my p400 looked identical to this. Good nozzle checks, poor jet ability. Used new magenta inks, problem went away. So I used old magenta in a p800, no issues for a few months, then it did the same. I threw out the ink and got new- problem solved. however, another time it was a failing head, from what I understand the peizo crystal weakens causing less “ suction” creating this issue as well, while showing good nozzle checks because it’s a short burst. and yet again, another time is was a bad cartridge. It looked fine but when put on its side and sucked ink from port, it just pulled air. New cartridge didn’t do this. New cartridge fixed the issue. Anum is also correct about the film, but I had assume this was tested already. since other colors are fine, it’s unlikely. Also unlikely anything wrong with feed mechanism since other colors are fine. good luck Edited May 6, 2022 by johnson4 Quote Link to comment Share on other sites More sharing options...
Carlos4072 Posted May 6, 2022 Author Share Posted May 6, 2022 Thanks both for help with the possible failures. I have 3 sets of cartidges, so i can check that easy. Also i have other brand ink, and if that the problem is too easy fix it. The prinhead is almost new, no more than 500 prints, of course i know that even with few prints could be defective. I already tested many films, but in my L1800 this films are workin flawless. Anyway, i go to take some days for change everything, also i can change the printhead to a 3880 and test if is doing the same in other printer, in that way i can discard a mechanical issue. I appreciate a lot your help guys. Quote Link to comment Share on other sites More sharing options...

Carlos4072 Posted May 9, 2022 Author Share Posted May 9, 2022 I spended the weekend making more test. Unfortunatelly no good luck. I switched cardridges, and changed the ink for other brand. But still getting same results. Please if you have other idea about what could be the problem, let me know. Quote Link to comment Share on other sites More sharing options...
johnson4 Posted May 10, 2022 Share Posted May 10, 2022 Honestly I have no clue. at this point I would have swapped ink channels/heads to see if the issue followed the ink, or if it stayed in that channel. My guess is the printhead since you have done everything else. Quote Link to comment Share on other sites More sharing options...
anum11 Posted May 15, 2022 Share Posted May 15, 2022 (edited) You are most likely missing something. Take a step back and work on it later. Edited May 15, 2022 by anum11 Quote Link to comment Share on other sites More sharing options...

Ibraheem Ansari Posted August 19 Share Posted August 19 I also have an Epson P6000 DTF machine and I am facing the same problem. I used to buy ink from (Jet Cartridge) Company who is my engineer, but they used to provide me ink in their ink (White 5000 Indian Rs) & (CMYK ink 3000 Indian Rs). When I came to know that ink of another brand is available for (1600 Indian Rs) I purchased it and used it. I did not have any problem for 3 months. And just a few days ago, the rainy season came and it started raining and I had menstruation and I faced the same problem. So when I talked to my Jet Cartridge (+91 98694 47140) Engineer (+91 98690 54516) about this he told me very rudely that I will not be responsible for purchasing it from somewhere else. I requested him a lot but he did not receive any of my calls and now I am very worried. What should I do about this problem. Can anyone help me?https://drive.google.com/file/d/10dE9OsZMxw4b17sTnfpNfe87UrG-dkOT/view?usp=sharing https://drive.google.com/file/d/1ZVuopflqAwmOt4oZh1MV_XuTkTzZw8SA/view?usp=sharing https://drive.google.com/file/d/1iLI6ZxnLjFUiE6GA3PG6NKQFYlzb1el5/view?usp=sharing https://drive.google.com/file/d/1soENXpg3z8SSO-7c2Lf0aCJ7y6i3wcmW/view?usp=sharing https://drive.google.com/file/d/1P1CqQx6YO9byWHUiSNJnBF8L0zIilxp6/view?usp=sharing https://drive.google.com/file/d/1J03cJ-_0tYtvqJyuY-c7hwbVHZZQUm3_/view?usp=sharing https://drive.google.com/file/d/1HfgOhnADKwt5nX30vGHarxZ8oZ3LnuYm/view?usp=sharing Quote Link to comment Share on other sites More sharing options...

I also don't switch suppliers very often, if I find it cheaper I tell them and they usually price match. Anything ink related, or printhead related, I always start at my last known spot and start there. I flush ALL the ink lines, replace the dampers, and flush the printhead until the cleaner comes out clear. I start fresh with known good ink, new dampers, flushed clean lines and printhead. From here, I just proceed as normal and do standard preparations to fill system with ink and ready to go. This usually requires a little flushing and head cleaning. Once done, if the problem is exactly the same, I will start problem solving to find the issue. Swap around the ink lines/colors on the problem channel. If the issue follows the ink color, or not. This gives you the answer, not concrete, but very likely. It will either be the ink, or the printhead at this point. The P6000, I have one over a year in service original printhead. The other one, I ran it when it got hot here. Before this, the printer was one head clean, print all day. I mean ALL day for 6+ Months. We had a heat wave and my A/C was terrible for it. It was actively around 90-95F and this heat caused my printer to drop nozzles like crazy before I noticed, so it ran for at least an hour like this. Permanently damaged the printhead. Yes, I can get nozzles to clear, and work, but not consistently. I have to do many cleans a day and honestly it just isn't reliable anymore. Replaced the head, problem solved. Replaced the A/C, Future problem solved. Most head failures are straight up user error and mostly environmental, so people don't see a clear reason for failure. As for the ink, No matter where it comes from I run it through a 5 micron ink filter. They are like 50 cents a filter and I change them every 3 months. Cheap and simple reassurance at least for larger particles. IF I see build up on any color after 3 months in the filter, ( which I should not) I have to find a replacement ink because that is unacceptable.
