Also, the alignment won't make any difference as this just tells the printer where to cut. If the sheet moves out of alignment at all the printer doesn't know this, so thinks it is cutting in the correct place

There are a couple of common reaons this can happen. I assume you mean the cut is ok across the width of the sheet, but goes out on the length? With the cut being ok on lower pressures though it sounds like your pinch rollers aren't holding the vinyl tightly enough. This can cause it to slip...

When the printer cleans it sucks the ink more powerfully through the head than during normal operation. This can fill up the damper and head, and give enough ink for a good print for a while, but as the suction is a lot less when printing if there is an ink supply problem ( could even be a...

If it looks ok it should be fine, as long as it looks centered under the head

Also check the capping station is aligning to the head properly when the job finishes. If it is leaking air at all this can cause the head to dry out overnight

OK so if you have a new head, and it is printing ok for part of the job then you can rule that out. There isn't anything after the ink or head to go wrong. If the head is getting the correct supply of ink, then it should be printing ok. Are the test prints on the new head ok, and did you also...

Yes remove the fuel. It is much easier to work on the tank when it is off the bike anyway, so do it when you remove it

Does it do it on every print you try, and if you try a small job, say 6 inches long, does that print and finish correctly? If they have changed all those parts, then it doesn't sound like a hardware problem with the printer itself, I am wondering if something is going on with versaworks and for...

No problem :)

https://downloadcenter.rolanddg.com/LEC-330#software it is on this page, download and extract the updater and that is what you use to install it

see below

The answer is on the pic you have posted. You need to download the firmware installer from the download center

I really wouldn't worry about it. On my old SP I have replaced heads and entered ranks and not entered them and have never seen any difference in print quality or longevity. I really think any difference between the heads is so tiny that it doesn't really matter if you don't enter them

But check the top of the head too, a cracked manifold can also cause a lot of ink spillage and sometimes it can miss the head and come out the side of where the head mounts

That looks like the ink bladder inside the head has burst. This will make ink overflow from the metal casing of the head and cause this sort of leakage. Clean the head off around the sides and see if you can see see ink seeping from there. I dont think ink is leaking from above the head as...

It is probably the pinch sensor on the left of the printer. This senses when the cutting head reaches it and stops it so it doesn't run into the end. Not sure which model you have, but if you go into service mode you can do a sensor check and see if they all seem ok.

That can be normal with orange and green tones as these are the hardest for the printer to reproduce. it may also be how the gradient fill on the artwork was made. For example in Corel with a gradient fill you can choose between 256 and 999 bands for the quality

yes, service manual is the best to follow.

I don't really do full wraps myself, but I would guess based on surface area you are looking at about 5 times as much work and size than doing a standard small van, so price based on that.

From the look of the test print and what you have tried so far it looks like it is time for a new head. The test prints show ink is getting to the head fine, so changing the dampers etc... won't make any difference as it's not starvation ( if it is ink starvation then the test prints will be...
