Hey question, I think we got sold counterfeit or aftermarket DX7 heads..after installation we noticed on the packaging ect. We have a Roland XR640 and we’ll not sure what to do…

[@moonrakercat]

I'm impressed - you really know these print heads - Finally someone who knows their *hit !!! Keep up the good vids Mike- I really appreciate them !

New sub here did you ever put that video out on how to fix delaminated print heads I have 3 dx7 needs fixing thanks for the video

[@jareddoig]

Am interested to see next video! have tried to reseal before with no luck. I have found a very effective flushing method especially for the black channels that become "shoelaced" over time.

[@reprint217]

Love the "shoelace" never referred to it as that but exactly what it looks like! Lets connect love to learn your methods

[@urbanimagefongwe9221]

Hello nice to come across your chanel, I have two brand new of those printheads that where bought for the Epson Gs6000 but were never used. Can they work on the roland? Or how can I sell them.

[@SHG_CO]

Hi! getting a perfect test print on my VS-540i but get empty dots (fish eyes) throughout prints intermittently...have to do a head cleaning 2-3X and sometimes it goes away.

[@reprint217]

I helped you solve this correct? Wanted to make sure didn't miss anyone

[@afroninjadeluxe]

On Epson R2400, UV ink dissolved the ink manifold where the cartridges rest on, the plastic was softened and disfigured so no ink could flow through the holes. I see the "ink spray station" melt away to plastic goop.

[@reprint217]

Uv ink is very volatile and some printers are not made with solvent resistant parts. I see this alot with conversions.

[@richardpendame]

I have DX7 printhead. Lately when i print, during the print it changes colours. It starts off well then starts printing a different colour or shade. Please help. Thanks!

[@reprint217]

Sounds like your printhead may have started delaminating. You can send me nozzle check pic and symptoms 217-413-2532 can text or whatsapp

[@hgpsale7605]

Do you sell New DX7 Print Head with with your patent glue add to the side of the head?

[@reprint217]

Sorry for confusion, my words might be seen in wrong way. I do not hold patent on glue. I read the patent of the manufacture that stated what glue they use. I have new printheads for sale but not refurbished

how much to fix head? mine has a small crack under the cage

[@reprint217]

They are pain in arse to fix. Yours maybe manifold issue

[@bradkress7492]

@@reprint217 It is leaking on the side. just a hairline crack around a 1/4 inch long. Head is flushed and clean.

[@emreagirman6173]

I attempted to clean the manifold by sucking solution thru the head, after putting the dampers in place and installing the printhead, the cage where the dampers are filled with ink. Do you think i did not put in the dampers correctly or i messed up the head when pulling solution up? Also this happened when the printer was on and printing something, so it threw the 075 code, i removed the head again and it was wet/ink all over the electronics parts. i hope i just fired the head and not the motherboard. what do you think? Thanks in advance.

[@reprint217]

Oh man, had a damper blow and cause this. Not a pretty sight. Likely would have tripped a fuse if it was on. I can fix if need be. Also may have head for little cheaper than online prices. I have too many at moment.

[@emreagirman6173]

i wish i knew it before, i bought a new head already, put it on. working right now. I might call you about some questions on the sts 628. Thank you for all the great videos. It helped me and i was able to replace my head on my own, rather than paying a tech. Keep up the good work. @@reprint217

Hey, did you even post of video on re-attaching the nozzle plate? I cant find it :/

[@reprint217]

I have the content and had it on here for a little while but became messy. I sent few dx7 heads and small batches of glue. And nobody was able to do it. Only one had a good microscope. After I ran out of the glue I pulled it. The glue is over 200.00 and I didn't want to be responsible for someone wasting another 200.00 I may repost when I order more and can sell smaller qtys of the glue for those wanting to try.

Can you make an image where the adhesive gos on the print head do you have to go around each nozzles with adhesive?

[@mobilewindowtinting120]

Print head not gloged xp600 When flushing hardly hearing the ticking frequency that spurt,so it's not spraying the ink out of head How can I fix Send foto to where issue can be Thanks

[@reprint217]

Sounds like some kind of build up in the head. Ive seen cases where some ink channels waterfall nicely and others take alot more pressure. Pulled the head apart to inspect and found a mound of dried ink.

[@mikeferretti7422]

Do you also buy printheads? I got a free bn20 and starting with replacing the cap top and dampers but if I have to replace the printhead would you do a buy sell deal? I'm gonna soak it for a few days and see.

[@reprint217]

I wish the used heads had a value as I have many. Yes keep soaking. If head clogged from lack of use. Than they are pretty easy to save. But majority I receive the original owner stopped using because printhead failed

[@lazerpug]

Hey mike! I replaced my print head and my 540 came back to life but the ink itself literally won’t fill the tubes. Is there a priming procedure?

[@reprint217]

Couple power cleanings ink should be flowing unless you have another issue. First I would check the captop and pump. Gravity plays big roll with the ink delivery system so usually couple or few cleans should get you some progress.

[@lazerpug]

@@reprint217 some of the inks responded to the "fill ink" command and the captop seems to be working because ink is passing through the head into the bottle. The bizarre thing is that when trying to run a test print it does not even put down the colors that clearly have ink in the tubes

[@cncmechtech]

So, I think i saw a printhead doctor unit in one of your videos. Any chance you might be willing to share what your experience has been with it? I just got an XR640 and have an LEF2-300 on the way that both need major head cleaning. I'm wondering if it would be worth it to have that device on hand to both try to recover the heads in these machines that were left sitting for a while as well as to perform some kind of gentle periodic maintenance flush to keep the heads clear as time goes on? I'm gonna have two DX7 and 4 DX4 printheads that I'd like to keep in top shape for as long as possible. It wouldn't take bu a few replacements to equal a cost of a printhead doctor, even the more expensive models.

[@reprint217]

Love my printhead doctors for industrial heads. At first i was impressed at how it unclogged but every epson head I ran through the machine either was doa as soon as put in the machine or failed shortly after. Epson heads are very sensitive to any type of pressure. Highly advise against it.

[@cncmechtech]

@@reprint217 Got it. I was really hoping vacuum assisted reverse flush at super low pressure would be a bit of a magic bullet. Just set it and let it run at next to no pressure for a long time instead of the soak, rinse, and repeat method. Just thought maybe that a slow but constant circulation of a cleaning fluid would keep flushing the surface of the clog with fresh cleaner and be a good idea. Thank you for the feedback!

[@t_story5544]

Question, is there a way to tell that your DX7 printhead is fried? signs? I have a 1324x printer. We had to change out our printhead as there was an error message we were trying to fix. So printer sat for months and months. Anyhow, changed out printhead and no more error message. However , when printing on media nothing prints at all. inks are charging and empties out in waste properly when cleaning. we were told printhead may be fried. (we've also check the fuses on mainboard and CR board and they seem to be working) We live in the islands so its really hard to find a tech here to come out and see. In need of help please

[@reprint217]

These heads are very sensitive and ashamed to say even with changing out 100s of these heads I too have ruined a brand new head. If you know ink is flowing and fuses are good. Than likely head is electrically shorted out. In my early days being self taught did this a few times and it sucks

[@t_story5544]

can you please share the glue name?

[@reprint217]

Epotek 353ND, available from Epoxy Technology Inc., and Ablebond 931-1T1N1, available from Ablestik. Ablebond 931-1T1N1 is preferred for its thixotropic properties but is less resistant against some type of inkjet inks, e.g. water-based inks. Epotek 353ND on the other hand has good ink resistance properties but is not thixotrope and thus can easily flow into the ink chambers if the adhesive was applied too thick or if the nozzle plate was pushed too hard against the front surface of the printhead body.

[@reprint217]

This is from the Patent documents if the printhead. They use 2 adhesives. Epotek 353ND, available from Epoxy Technology Inc., and Ablebond 931-1T1N1, available from Ablestik.

I did, however, I removed it as most people just wasted money on the adhesive. I had a large bottle and supplied some to a few as it is pretty costly. Didn't want to be responsible for people losing money. I've been working with one guy who has had a pretty good success rate, but I had sent him 20 heads to play with beforehand. Took him destroying the majority before making progress.
