UCJV330 wakes up every 20 minutes when power off

[juki]

Does anyone with a UCJV330 have the same issue?
When the printer is turned off, it wakes up every 20 minutes to reseat the capping station, then shuts down again. The dealer says this is normal, but I’m not convinced

It's normal. Without it you're inks would freeze up and become nice little bricks

You can turn the setting up to give it more time between refreshes but yeah, it's a built in feature you can't turn off to prevent head clogging.

if it does not do it, your ink will dry up and you will have to replace print heads very often....... hope this will convince you more than saying it is normal.

If your ink dries, you're using the wrong ink. It's mostly to prevent sedimentation of white ink, so it is mixing it to keep it from separating. White ink is the killer of printers if not agitated on the regular. Some cycles are also purging tiny bits of ink from the head, but that's way less frequent.

Does anyone here actually have the UCJV330 to double check, or are these just guesses?
I’m not talking about refreshing, circulation, or periodic cleaning-those are settings you can adjust on the machine.
This is something you can’t change, and there’s no mention of it in the manual or machine settings. When the machine wakes up every 20 minutes, it only performs a capping re-seat - nothing else.

Regarding white ink, it’s not as scary as some people think. I have an older 3042FX, and it’s been perfect-even after being left off for 2–3 weeks and its without white ink circulation

The 330 wakes up more than older models, yes. Do I own one? No. But I work on them multiple times a month and have done everything from installs to head swaps.

Mine does a refresh every 24hrs. That takes like 20mins to go through....the other one I think it's just shooting some ink through the heads. Lasts for a minute or two and turns off again.

Did you notice that on the other 330 machine you have installed, it wakes up every 20 minutes after being powered off? Just want to check if other machine doing same

Your ink configurations is CMYKWWClCl ?

Yes it is. Occasionally it will refresh during the day but I it's so infrequent when it happens. It's more annoying that when it's on after about 10-15mins that it goes into circulation. (can cancel it, but still annoying)

i think your setup is the outlier if you have never had problems with white ink
just the absurd amount of solids in suspension is trouble looking for a place to happen & if you tell the truth you are probably not happy with the white (you would prefer more density)

Besides refreshing, white circulation, and self-cleaning, my machine wakes up every 20 minutes for about 20 seconds. Mimaki Japan confirmed this is normal, as it checks the temperature. It seems unusual, but we’ll see over time whether it causes any issues. The older 3042FX has been running reliably for years, whereas the 330 has been problematic from the beginning ;/

The 330 has some weirdness to it, they wanted to make a single machine with 3 variants based on the 3 versions of the i3200 printhead. Aqueous/sublimation is the TS330, solvent with the CJV330 and UV with the UCJV330.

The white in the 3042fx LH100 - regular shake, regular white print, 5min Nozzle wash at finish of the day print - that's the secret.
