I've run into this type of issue on Rolands before and it's usually an encoder issue. I don't know if the VS models are the same as older ones but I would usually run the linear encoder setup and linear encoder calibration in service mode and then the environmental match in user mode. That gets...

You can also just use the same spot color you did on your Roland for the contour cut. Flexi will pick it up just like VW. Also, there is a button next to the media width options that gets the media size from the printer. Maybe HPs don't support that but I'd be surprised.

There's no official end of service date for the UCJV300 but the UCJV150 model's end of service date is 2027. I'd assume the UCJV300, which they made many more of, will be similar or longer.

$200/hr is fairly standard these days although most places will give you a break on the travel if you're in town. It comes down to basic supply and demand in my opinion. There are very few techs to go around and even fewer good ones. Low supply and high demand always brings high prices.

You need to run the bi-directional alignment in service mode to zero out the user mode ones.

Even your dentist sends the mold to another guy to make the crown.

"Refurbished" heads are a myth. You can flush a head and put a new manifold on it but that's about it. If the piezo crystals are damaged or the physical nozzles are deformed/delaminated, there's no recovering.

Higher heat settings might help. Looks like when heat is too low.

This is one of the more common failures on this machine in my experience. The circulation pumps tend to have leaks like this over time. You could try opening them up, cleaning them out and replacing the broken ink line, or just replace the pumps. Not sure if Mimaki has come up with an upgrade yet.

As APCink said, most likely one of the cartridges is expiring sooner than the other and it switched to use the closer expiration date first.

Try Joe Reyes. I know he works on Mutohs and Mimakis so wouldn't be surprised if he does Rolands as well. 210-376-8783

The UCJV300 is a good, reliable machine, but a lot of people stay away from UV for wraps and mostly because solvent or latex is a proven solid solution for wraps. From what I've heard you can do wraps with UV inks but installation can be harder due to it preventing stretching etc. That being...

We get W9 requests from larger companies/customers and it's usually just to have our EIN on record just in case. I think they do it to verify your status so they don't get in trouble during tax season. Since we're an S-corp, they just file it away but if we were an LLC they might need to send a...

If ink is receding back up the tube, you most likely need new dampers and/or the o-ring seal between the damper and ink line is bad. The dampers are responsible for regulating the pressure in the ink line.

Mimaki recommends using a USB cable no longer than 14 ft. with no hubs etc. For some reason they are more susceptible to noise than other printers.

Make sure there is actually nothing in the file in that spot. Not even a white background. I know logical seek will skip feed direction on older Mimakis but they may not have continued that on your model as too.

I believe if you go into the Setup menu and turn on "Logical Seek" it will speed up the feed in those spots.

It sounds like maybe the head is failing. Sometimes the variable dot function will malfunction and only allow a certain sized dot to to fire. So that would explain why it fires on the nozzle check but not more involved patterns that may use the variable dot function.

Make sure you got the wipers in the right orientation. If you put them in backwards they don't make good contact with the head surface. Sounds like ink is being left behind which would cause the contamination. Also, take your waste bottle off and hold it under the waste tube and run a cleaning...

I've sold many many maintenance stations and in my experience some make a lot of noise and others don't. It doesn't seem to affect the function most of the time. Mutoh does recommend greasing the gears on new stations as well which most people skip. So that may help. 3rd party stations fail far...
