A question, does anyone know if double white lines are faster than single metallic lines? CMYK-Cl-Ml-MT-W or CMYK-Cl-Ml-WW

I would remove the cartridges, close the choke valve, then remove the dumpers from the head and remove the ink manually with a syringe. Or take out the cartridges and ask the printer to clean the lines. Then I would put in the new cartridges and refill without further ado.

How can you print only with CL or ML? I have never been able to get the RIP to recognize printing these colors alone without mixing M or C.

Hello I recently bought a vs640 and noticed that it has the stock firmware version 4.00 installed. I would like to know if anyone has performed the updates. If these had changes in operation or some restrictions. Since I use red gaian inks and they are not original. I wouldn't like to update and...

Material?

thanks. the label is erased, someone cleaned it with solvent.... I never created a peck file, how do I have a backup in case something happens?

Hello everyone, due to a quick finger movement error... I changed the serial number of my Roland VS640. I don't have the same one and since I didn't know which was the original, I didn't turn off the equipment and I didn't do anything else. Can this affect anything? I turned it off and on. I...

.Hello, yes you could change to white but you will have to clean the system more than the tubes and the head, you will always have something contaminated so your white will tend to the old color of used ink

This is DX7 chinesse delaminated head

I don't know what your story is my friend. But it may be true that the original parts are better tested or are of 10/10 quality, but sometimes and mainly in underdeveloped countries, these cost a lot of money. That's why you end up resorting to pieces from another origin that may be 8/10 but...

did it give results?

The vast majority of heads die from what I call delamination, which is the separation of the outer layer of the walls that lead the canals. But from time to time what happens is that the channels become clogged and by carrying out too many cleanings the first thing happens. So I help the head to...

I'm really going to tell my experience that seems to be pure coincidence but with 35w ultrasound and flushing liquid and saved 4 dx2 heads that have been printing for years. and a Chinese dx7.... my method is that the head does not touch the bottom, do short cycles of 2 or 3 seconds and...

Ok, just make combinations of numbers that give an original headrank?

Another question because it does not allow changing the head rank numbers. When you change any number and press enter, the device emits a double beep and it does not change...

No, I don't know its origin, I bought this equipment used, it has a head that is broken in its black delaminated channel. and this other one was given to me by the previous owner, I cleaned it with ultrasound and tried to insert it to see what his response was... but it didn't print anything...

if the meaning is correct

with the previous head range it does not emit ink from any channel. He also did not manage to save another head rank number. When trying to change a number that is on the device, it does not allow you to record it. it makes me double blip

Hello, I have a question. I wanted to make a head change on my vs640 and when I entered the head rank, the machine did not recognize it, that is, it made two blip blip sounds and did not make the changes. I also ran into the problem that the head has fewer numbers than the previous one. I...

Any advice to keep it in good condition. I'm going to configure my vs640 with w + mt...
