Check your head cables for any damage, ink splatter, or corrosion and change if needed. Unfortunately if it's not the head cables, this issue looks to be electrical to me which would point towards a damaged board. What was the original reason for changing the head?

Good ideas above. If none of that works, you might need to adjust the sensor sensitivity. It's not something that is in the user manual though. It requires a voltmeter as well.

Yeah post a nozzle check but my first impression is ink starvation. Have you changed the dampers recently?

If the sign is in public, you don't have to ask permission to take a picture of it and post it on your site. Now you might have an ethical, moral or business reason to still want to ask permission but legally, taking a picture in public and posting to your site is well within your rights.

That's where I usually print and cut a crosshair. It gives you an idea of how far you need to move it. It will take a few rounds of printing and cutting the crosshair and changing the adjustment to get it spot on.

It's in the mark detect settings. You have to be in cut mode and then just hit Function>Setup>Choose your tool preset>Mark Detect Once you get to Mark Detect, just hit a few times and it will scroll through the Mark Detect settings. 2 of the settings will be X and Y offset and those basically...

Are you using crop marks? If so, have you adjusted the A and B offset in the mark detect settings? If the cut is off by the same amount every time, that's the setting you need to adjust.

Good to hear! Encoders can do weird things sometimes.

Make sure to change the dampers, replace the cap top, and flush the pump lines with cleaning solution while you're in there changing the cap top. The contamination could be coming from any of those items failing. It's still likely the head but it's worth a shot to change out those cheaper parts...

I'd suggest getting a tech. It's going to be some sort of electrical issue and a tech should be able to isolate where it is. This particular model had issues with electromagnetic interference so if you've added a new piece of equipment recently, try powering that down and see if it changes...

I agree with above but you might also change the dampers and see if that helps at all. Sometimes a bad damper can cause such bad cross contamination. But it is very likely internal head damage.

Unfortunately that looks like an electrical issue. Have you received any random errors recently? Especially if you have been getting FIFO underrun errros it would indicate a bad trailing cable.

Ideally a damper should be about half full but it's very common for them to be completely full especially on older dampers. It's also more common if you use a bulk system for them to be full. Be careful taking those dampers out for too long as well. Exposing them to light for too long could clog...

You probably popped one of the head fuses on the main board. Double check your head cables to make sure they are plugged in nice and straight and aren't damaged or dirty. Then test the fuses on the main board. I've attached a picture where they are. They are 750mA fuses and user replaceable.

That sounds more like a profile issue to me. Are you 100% no one has been playing with the color settings in Rasterlink? Maybe the default profile was changed?

The amount of ink spent on cleanings is well worth keeping the head working. If the cost of waste ink is breaking the bank, something is not setup correctly. As a dealer I've had floor models that don't get used very much and only sit there doing cleanings for the most part. In my experience, if...

If your dealer tech doesn't offer the service, your best bet is contacting Mimaki directly. They are right there in Georgia so I'm sure one of their techs can help you out. But as mentioned above, watch some YouTube videos and play around with it. That's how a lot of people learn it. Also, PDS...

No a cleaning cycle once you get it to the new location. It will get bumped around when moving so there might be some air bubbles that needs to be pulled out but usually it only needs a simple cleaning and you're good to go!

There is no rubber latex in latex inks so you're good from that perspective. The polymers in the ink are latex like so they call it latex ink which is confusing. Also, certain people are sensitive to UV inks. One guy here on signs101 had a pretty intense reaction to the inks and basically...

I'd clean the encoder strip first. It might just be a coincidence that you're only seeing it in the cyan but vertical banding is usually caused by a dirty or damaged encoder. It could be the head but I would change the dampers before changing the head to rule them out.
