Turns out my colleague is quite familiar with the JV33. His questions were: 1) How old is the head? They use an Epson DX3 or DX5 head that are rated to 6 billion drops, over 10 billion drops he has seen it do exactly what yours has done, and it's impossible to get it back to how it was before...

Gee, that actually prints even worse than I expected. It really is putting the cyan down rough. We don't ever get problems with not enough humidity here, in fact we have to have air-con on 24/7 to keep temps down and keep the moisture out of the air. I'm certainly no tech, but I can't imagine...

The fact that the nozzles are all firing, just out of alignment, says to me that the head is grubby. In those cleaning processes, did you do the one where you fill up the capping station with cleaning fluid & you tell it how many minutes to soak it for? I forgot what it's called, sorry, haven't...

The problem with mine is that on, say, my Mono preset, the colours are very green. On my Poly preset, they're now a purple colour. Others have gone in different directions, and these medias were all offshoots of the Poly preset (ie, I made the poly one first, then I duplicated this one to make...

I'm of in a holding pattern, waiting for the HP tech to visit. At the moment I'm running all of my SAV (literally all of it, mono, poly, cast, wall, etc) off the one media preset, the new one I made as a test that seemed okay. I know the white points will be different but it's better than having...

If it's been working until now I'd say your materials aren't the issue. It'll be the surface it's being applied to. Especially in a restaurant, over time there will be a buildup of grease, and a normal spray & wipe won't cut through it. I'd suggest they clean it with an alcohol-based cleaner...

Are you using genuine inks? Our JV33 printed flawlessly for 4 years before we ventured in to 3rd party inks, which resulted in exactly the problem you described. Among countless other issues that had me homicidal.

Each to their own. If it works, it works!

It'll depend on whether the profile has been set up to switch between V and W. I haven't had our Roland for about 4 years now, but this screen dump below looks about right, you'll see in the Quality tab there is a Mode option. On the screenshot it's greyed out, meaning it's only been set up for...

Because I come from a world of designing in 2D and I'll be damned if some 3D surface is going to dictate to me how my design will look ;) What do you mean by slant though? If done right, there will be no slant. It will appear skewed on the print when it's lying flat, but not when it's on the...

+1 to increasing the # of passes. If you can't afford a new print head and the various cleaning operations (you are cleaning, right? including a weekly one where you soak the heads over the weekend?) won't fix it, increasing the passes is the only way to improve it. Depending on your profile...

Gun post. All of that is pretty bang-on. The only thing I'll add is that you can actually measure the swoop. You have to do it on the vehicle though, not the tracing. Using a rigid tape measure or a straight-edge that can curve on one dimension, put the zero point on roughly the top left...

I guess this means that I'll be writing down all of the settings for every media, and then making them again from scratch. The question is, how long until someone else at HP puts something in the next firmware that'll invalidate these new ones???

Isn't it the opposite? On the window, the paper will be higher at the middle and lower towards the edges. That's a "frown". The print will have the opposite - it'll be lower in the middle - the "smile". I know I live on the underside of the Earth, hanging upside down, but still...

I think the question is "The printer uses a firewire cable. Which won't plug in to my laptop. What can I do"? We ran our JV33-160 via USB. Does your printer have a USB outlet on it? Don't worry about the firewire vs USB transfer rate - the printer can never ever print fast enough to outrun the...

I'm still waiting for the HP tech to contact me. If I get any answers from him I'll be posting them here immediately. I kind of trust this guy, more than any previous HP techs, because he's the only one who ever admitted that horizontal banding is an issue on the L28500s & L260s. Every other...

The only way I've been able to access it is when I go through the Printhead Cleaning Kit swap, or Ink Maintenance Kit. Not sure if you can do this process to access it, but not actually change it (as in the printer might detect that it hasn't been swapped and stay in a holding pattern). An Ink...

We have a 480XT which is about 2 years old now. The white starts to block up after about 10 minutes (if the ink heater has turned itself off, time to re-clean) and the yellow is not much better. The white one is normal (though ours degrades quite fast), but the yellow one is because of the print...

What rip are you using? We had ours through Rasterlink, and then through Onyx, and both had the 3 heating settings (pre, print, and post), and vacuum settings easily viewable/adjustable. And by the sounds of that, yeah, if it's only effectively the outer layer of the roll that ripples, it's...
