It's a common problem with UV inks even with other manufacturers. Find a dealer who will drop ship them directly from Roland and you'll get the best expiration dates. But even then, you might not get much better results.

The RIP process is non-parallelizable so it can't use hyper threading or multiple cores. I assume setting it to use CPU 0 only fixes some sort of data flow bug in the software. Multiple cores only benefits the RIP process when you want to RIP multiple files at once.

Roland had a good reputation when they were making SP-300s that lasted 20 years and are still running to this day. Somewhere it went downhill and they started pumping out budget printers at full price. Might have something to do with them going the private equity route.

It's hard to say. Here in the midwest it's a no brainer because of the natural humidity. You have to keep the windows open to keep the air flowing. if not, it gets so humid it's unbearable. With a dehumidifier, it might act as the open window. Plus the internet says it works so there's that.

We cool our 8,000 sqft warehouse with swamp coolers which is much cheaper than AC, but if you're having issues with humidity, that probably won't work in your area. Your printers should be working at under 86 degrees. Maybe that will sway the boss to cool things down a bit.

I honestly don't know how well it works on acrylic but from a technical standpoint, it's definitely tougher on the head. It's hard to say exactly how much life it takes off a head but it will fail sooner than it would have with regular ink running through it. So maintenance will be key. Also, if...

My sister is looking to create custom playing cards for her company that she wants to find a supplier for who would drop ship them directly to people who buy them. They would be about 4" x 6" so not standard playing card size. Anyone here on signs101 do that kind of thing or know of a place that...

The general lifespan for that head is 6 billion shots. That being said, there are many factors that will affect that number and overspray can be caused by other issues in the printer or bad ink for example.

I would say if the end customer didn't provide any original art work and just gave a description of what they wanted and you did the design work, technically you own the artwork unless you signed away ownership in an agreement of some sort. You might just tell them, in the future, if you want to...

With that printer, it will probably just over saturate and make it look weird. Texture is best left for the UV printers.

There are a lot of rural sign shops that don't have a near by tech and can't afford to fly one across the country to their shop. There are also relatively few techs compared to the amount of printers. Low supply and high demand cause tech prices to be fairly high. A lot of sign shops are started...

I'd love to spill the tea someday when I'm not representing someone else's company. If you're still around by then, I'll look you up!

Every one of my ink suppliers raised prices 10% on June 1st except for Mutoh.

HP has something like that but it's more for mass production. https://www.hp.com/us-en/commercial-industrial-printing/pagewide-web-press.html?jumpid=va_37f3aac8b1

The original ink for that machine was called Eco Ultra ink. Now it's just called MS31. It's still a current product and you can get it from any Mutoh dealer. If you want to save money, Bordeaux also has a third party option that works well.

That or my first hunch is the head lock mechanism is either not disengaging or is misaligned causing the head to remain locked when it shouldn't.

Your printhead can fire different sized dots. The nozzle check uses the largest one. So you can have issues with a print head even when the nozzle check looks perfect. Try printing the nozzle check in service mode. That will print the other sized dots as well and will probably show defects.

The first errors you received mean the motor was experiencing slight drag that became too much to overcome. The second set of errors means it's experiencing a large amount of drag really quickly. Since the encoder setup didn't fail immediately, which indicates the sensor was reading properly for...

07 is the one used for flushing the ink system.
