Amazing video. Just sent this to our customer now he can DYI. Very detail in every aspect. Did not miss any steps.
I waited 5 years for this video thank you very much
Sorry it took me so long lol
Thanks man! Great video!
Appreciate your support!
Can we get a link for the dampers replacement?
Hi. Great video. We replaced the head on our VS640i and after a couple of head cleans we are missing white and one of the magentas on the nozzle check. The other colours look great but we're not sure what to do next. We changed the head the dampers and the cap as we bought a kit. Thanks
Did you ever resolve? Sorry have been extremely busy
Hello. Thanks for the video - very helpful. We just replaced one of the print heads on one of our XR640s. I failed to save the packaging and don't have the head serial number. However, I did take photos of the head and there are numbers on it. Is the serial number on the actual print head? Just curious. If not, is there another solution or work around for this issue? Thanks in advance. ~Tim
Yes those would be the numbers you input!
hello, just replace the dumpers and this head was installed in other machine, the problem still the same, 7 lines of 8, any other reason u can recommend, thanks.
Send me some pictures signworx217@gmail.com
Great video and very appreciated. I have a VS-540 6-color and I'm missing my Black Channel completely and most of my Yellow Channel. I also noticed that the black ink tube is not filling up when doing cleanings. It is empty about 3" before the damper. The head was replaced two years ago but we haven't been using it very much lately. Does this sound like a damper replacement job to fix the black or is the printhead bad? I did an overnight soak and no improvements. I also checked under the Ink cartridges and the inside of the machine is clean.
Hey, Sorry, I have been in Atlanta at Printing United Trade Show. If still not resolved, shoot me an email. Signworx217@gmail.com

hi there, thanks for ur video. i have same problem on my printhead dx7, 7 of 8 colours are out, and 0 on the light black on the right side,
what should check? thanks.
I always start with a captop change.
i have used same printhead in another printer and same problem, still first line from the right side is missing and the other 7 are there, today i did chaneged 2 of the dumpers and still the same, thanks for your quick reply today@@reprint217
Nice videos! Recently got an sp540i and was wondering what is the best solution to clean ink stains on the plastic covers?
Bleach and magic eraser works best. If ink has actually etched itself in. Than I use headlight restoration kit and sand and polish
Hi. Bit if you change the Head by DIY, then you dont can reset the Count-Shot, i am right?
Yes you can clear it yourself in service mode-. Just Navigate to the history menu- and clear shot count.
I don't understand how to turn the choke valve off manually. You said turn it and also go into the service mode menu to turn off the valve?
Is there any way to get a service manual for a Roland XF-640?
Shoot me an email I will send you service manual signworx217@gmail.com
what do you think is happening after cleaning the printer and trying to fill the nozzles but no ink is pumping through
Clog somewhere. Clogged pump, head, captop, dried up ink lines. Lots of variables
Do you know which Printhead this Mimaki Model CJV150-130 uses?
Yes, I actually have a brand new one with the head memory board for sale. It's a DX7 . You can use cheaper DX7 heads, i.e., Roland DX7. However, the oem printhead has a head rank memory board that can be pretty important. The head rank provides info for proper voltage and firing. Most of the time, the old head rank can allow the printer to print properly, just not optimum. But every now and then, I've seen cases of electrical issues from improper head voltage. So it's best to stick with oem. I think there is about a $500.00 difference between the Roland Version and Mimaki version. I have one left for $1500.00, and it is the oem brand new with head cables and memory board
I joined the forum sign101 which i read alot of users seems to prefer Mimaki printers over Roland, and Mimaki cjv150 some still use theirs for over 6 years and still going strong. From what i read from your comments it seems DX7s print differ between both printers and their prices as well. Am thinking of replacing my roland xr640 for a mimaki 150 model, as new roland printer has many issue from what i read. Thank you for your advice
It seems Mimaki DX7 is way cheaper than Roland DX7
Helo sir please help me i have problem for my Roland rs 640 has an error e01010 what is the possible cause sir hope u can give me some information to fix. Thanks alot sir. Gbu
Try cleaning encoder strip
great video! I'm having some problems after installing the print head. so 4 out of my 7 colors work and three don't want to print. every time I do a test print it doesn't show the three colors but it will fully show the other 4. I'm wondering if I did something wrong during the process or if there is just some other under lying issue that I don't know. if it helps, we have a vs-540i
Feel free to give me a call. 217-413-2532 gladly help you out
Thank you for a great guide.
I'm facing problems after i replaced to the new head and dampers that when doing an testprint - theres nothing printing..
I can see when i do the cleanings that the ink is flowing through the head - captop and to the waste tank. But when printing - there's nothing.
Do you maybe know what it could be?
You more than likely blew fuse on mainboard or a transistor.
@@reprint217 Thank you, it was a blown transistor on the mainboard.
@@RightHns how you work out it was transistor?
@@deehaytch8442 i measured the ohm on the transistors, one of them didn’t ”response”
Hello friend! thanks for the help. I have a problem. after replacing the head, damper, captop and pump, ink is not coming out of the head, nothing is coming out. I've tried many things, and so far nothing. Would you help me ? What can it be ?
Ok, so nothing is coming out into waste tank or nothing printing?
If its not pumping first thing I would check is captop. There is 3 connectors on bottom of captop. 2 should have lines coming off of them, the 3rd should be capped off! Ive seen instances where the cap comes off the third. Please check
@@reprint217 checked. captop is good. the ink does not flow through the captop. could the head be burned? what else can i try to do?
Hello sir, bought secon hand dx printhead from china,is it necessary to input the value after installation like what you did to new head in service mode?
It is best to input the actual headrank, but most usually work fine with old headrank but have seen overspray in certain channels and odd electrical problems if headrank is not correct.
hi there how much are the head for versa vs540i?
Cheapest place I know of right now is sign-in-global.us as they do not charge tax like some. Think they are about 1700 to your door.
Ok, so I have a vs-540i and replaced the head with a DX6 after recommendation from Digiprint. What is the difference between a DX6 and a DX7?
No difference, they technically were never called a dx6 or 7 they had long part numbers but some call them dx6 and dx7. You bought the correct one
Where do you purchase your printheads from?
Please check my other videos. Current best price is Sign-in-global. I have video doing comparison of my 2 top go to's
@@reprint217 Thank you. And thank you for taking the time to make these videos!
My pleasure!
