That is correct, you can continue to turn the knobs and actually put more pressure on the roller. However, the weight of the roller itself is more than sufficient for laminating and mounting. I have found using any add'l pressure actually causes more problems. Like others have said, I don't...

I agree, and most likely your issue is that you don't have even pressure set across your rollers. I have a US Tech AK-600 (bought it new almost 3 years ago) and had the exact same issues as you at first - short runs were no problem, long 6+ feet and it would start to wrinkle. It all lies in...

Is the line empty all the way back? Typically you can do a few little charges and get the ink pulled back into the lines. However, realize you will be wasting as much ink from the other colors as you pull with the magenta. A more frugal way is to manually pull the ink through the lines using...

Ah, you're probably right - I was thinking of the 545. The 500 is a very old machine - Roland's first solvent printer if I recall correctly. Not saying it can't be used, but did you check to see if that even has a heating element for running solvent ink? (I think I remember that was an...

Agreed. DX4 heads run about $800/ea and that thing has either 4 or 6 heads. Add in any add'l items and you could be looking at $5k or more just for parts, not including a trained tech to make it happen.

My first guess would be contamination. I've had it happen on new rolls right at the start, and on open rolls where it didn't appear until 100' in. It happens. You can try to peel off 10 feet or so and try again. If it is still occurring, or the areas are shrinking in size, peel off another...

Heck yeh! Let's see some pics! :omg:

I'm not sure. Usually cables go bad due to being covered in ink which eats through the sheath and causes shorts. Otherwise, if you had been in there replacing the head or fixing something to where the cable would be loose or possibly not making good connection I could see that too. It...

Hmm, interesting. If you have time Chris, yes, please let me know what kind of costs I'm looking at either way. I will have to do some investigating to determine the culprit(s) Thank you.

Both Fellers and Signwarehouse stock ample parts for the Mutohs, I believe Advantage has a good supply as well. If you've never replaced your dampers, I would suspect that might have something to do with it. Get those changed out and then your MS and hopefully you should be back to printing...

Hi all, I've been noticing a noise occassionally coming from the head carriage on my 1604 and I suspect one or more of the bearings is starting to wear. Anyone ever replaced these, and do you know where to get them? Thanks!

You should be able to find a maintenance station for around $400-$500, new head is closer to $1k. Cables aren't expensive at all, comparatively speaking of course. How long has it been since you replaced dampers? Could be time if they aren't doing their job and the head is starving for cyan...

Ah, OK - thought it looked strange. Now that I look at your pics again, I would almost guess a heating issue, especially since it is on the vertical. Have you tried other profiles, and does the problem still persist? Also, do you see this on all media that you are running, or just certain ones?

Are you certain the lines are only running vertical? In the one pic it looks like they are running diagonal, unless you have that wording running at a diagonal on your print. (If diagonal, I would bet it's a cable issue/communication issue - especially if you just replaced the head. Make sure...

First, I have both a 1204 and a 1604. I have been told by a very good source that the head in them is indeed a solvent version not the same as a DX5 waterbased printer head. If you use a water-based DX5 it will work OK for a month or so until the solvent eats out the channels and the head will...

Definitely looks cool, and a low cost solution for those wanting to enter this type of market. However, I too have concerns about accuracy - but I wonder if it would be "good enough" for use on soft materials like PVC, HDU, etc?

We see this problem most often when there is solid ink coverage out to the edge where the grommet is placed. Typically, it's due to not being completely dry and the tacky ink "grips" the grommet instead of sliding/piercing like it should. *I bet a dollar that if you were to punch a grommet in...

I have a Keencut Excalibur with both the razor blad and cutting wheel attachment. FWIW - the razor blade does a good job on 4mm coro, 3/16 foamboard and 3mm PVC. The cutting wheel does work decently on .040 aluminum and 3mm poly-metals but it takes a good bit of effort and sometimes the...

Very interesting I would like to see some more reports from those using this tool

Are you trying to run with 440ml carts? If so, you may have issues because of that. If not, and it's doing it with 220's then you likely have an issue with the cards themselves, or I believe the mainboard. There was some other threads on here with similar questions. Do a search and see what...
