bovegas Posted March 30, 2017 Share Posted March 30, 2017 I am about to try UV LED ink in epson 3800 i just converted to flatbed. Do you guys know if i would just plug in cartridge and do head cleaning or i would need to clean head with some cleaning solution first and than plug in uv led ink. Do you know which cleaning solution i should use. Quote Link to comment Share on other sites More sharing options...

bovegas Posted March 31, 2017 Author Share Posted March 31, 2017 Not yet. Does anybody know how i should do it. I am not sure how UV ink will mix with epson ink Quote Link to comment Share on other sites More sharing options...
UVDTG Posted March 31, 2017 Share Posted March 31, 2017 Personally, I think I would run the cleaning fluid through it first, then add the UV ink. That's probably what I'll do if I ever get to that point Quote Link to comment Share on other sites More sharing options...
bovegas Posted March 31, 2017 Author Share Posted March 31, 2017 You mean epson cleaning fluid for aquious ink or uv cleaning fluid? Quote Link to comment Share on other sites More sharing options...
Andy - Admin Posted March 31, 2017 Share Posted March 31, 2017 I think any cleaning fluid to make sure 2 different inks don't touch would be better than nothing. Quote Link to comment Share on other sites More sharing options...
Longuini Posted April 1, 2017 Share Posted April 1, 2017 Keep in mind that water and solvent do not mix. Wash the printhead with fuid to DTG ink to remove the DTG ink completely. Certificate which has no more waste. Wash with isopropyl alcohol With this you will draw the water and exchange for isopropyl alcohol, as it evaporates quickly the chamber of the printhead stay dry, ready to receive UV ink. ok Quote Link to comment Share on other sites More sharing options...
Longuini Posted April 1, 2017 Share Posted April 1, 2017 Many do not know, but isopropyl alcohol is a great solvent for UV ink, better than the fluids sold on the market, as well as being cheaper. Quote Link to comment Share on other sites More sharing options...
Longuini Posted April 1, 2017 Share Posted April 1, 2017 Take the test before. Dilute uv ink with isopropyl alcohol to make sure. The ink can not curdle, sorry, I do not know if it's the term you use. Quote Link to comment Share on other sites More sharing options...

Zinalias Posted August 8, 2017 Share Posted August 8, 2017 Hi, i have a Epson L800 and a T50 (which are basically the same printer), I'de like to make them Uv printers. Other than changing the inklines to black ones and adding a Uv lamp and inks, is there another modification that's needed? Does anybody knows a tutorial on this? (i'll be printing cds and cards, the T50 and L800 already have a cd/card tray so i'll like to keep using that to avoid making a flatbed.) thanks!

Travb1999 Posted November 15, 2017 Share Posted November 15, 2017 After HEAVILY looking into this in recent weeks (Converting a 1430 but keeping sheetfed) I have learned to RUN from Chinese inks as they are a little on the harsher side. also stick to uv ink rated lines and tanks if using ciss as just painting them black does NOT suffice it will eat them. Apparently these inks have a "slight" solvent base to them. not harsh enough to damage the head but improper lines and tanks. Quote Link to comment Share on other sites More sharing options...

vittorio.granat Posted July 5, 2019 Share Posted July 5, 2019 Pay attention!!! uv ink is very corrosive.. you need a specific type of printhead. The printhead that yu can use fot dtv is not for uv. the same for the capping station . also you need a ricirculation system for uv white ink .

vittorio.granat Posted July 5, 2019 Share Posted July 5, 2019 In this moment i'm converting a epson r1800 into a flatbed UV printer with bed size of 30x100 cm ... shortly i will put the photos and the adds to arduino code for the lighting and ricirculation ink Quote Link to comment Share on other sites More sharing options...
Mister_X Posted July 14, 2019 Share Posted July 14, 2019 @vittorio Would be great to see your photos soon because i want to build also UV printer. Quote Link to comment Share on other sites More sharing options...
mansfieldexperiment Posted August 11, 2019 Share Posted August 11, 2019 I have a UV printer and I can share what I know thus far... UV Solvent based inks are crazy toxic!!! The inks that I pumped through the print head behave different than water based ink. I find that I have to flush my head about every 7-14 days with an insanely powerful cleaner that actually dissolves my vinyl gloves if I'm not careful. I didn't know what I was doing back when I started and accidentally got misted in my face by a gust of wind when I was cleaning the head outside. Not fun. Also in hindsight taking a printhead in the sun to flush out photosensitive inks is stupid. LOL Lessons. If you are going down this route please take every precaution for your skin as UV inks are much more toxic than what you are used to.

I used to used this. Found it just does not dissolve all the micro pieces of dried crusted ink very well. I know use "Eco Solvent Ink Cleaning Fluid" is what it says on the bottle. Its cheap and sorced via Ebay out of California. I do use alcohol still to wipe down equipment as the cleaning fluid is wicked toxic and I dont like touching it or using it much.

Id love to collaborate some time with you. There are few that I can find that make it all the way to pushing print and maintaining the machine.

Yes, I think even alcohol is better. I had fluids sold on the market that seemed to rather clog the head then flush it. If you think about it how they are sold in China, they might just stick the wrong label on the bottle... Quote Link to comment Share on other sites More sharing options...
