Default Leaving the Printhead in Cleaning Solution?

As anyone in DTG printing will know, keeping the white ink flowing through the printhead is pain! Especially those using Epson printheads as I do on my NeoFlex.

I don't print daily but have my NeoFlex set to carry out a self clean every 8 hours however, this alone doesn't keep the ink flowing and I often find some of the white ink channels are blocked!!

I usually have to remove the printhead and carry out a flushing to free the channel. I don't like doing this as there are many risks.

So, my question:
If I was to fill a small tray with cleaning solution and left the printhead in the cleaning solution with the printer switched off so it doesn't move or do self cleans, would this work and keep the nozzle free?

Look forward to any comments on this.

I'm also posting this in the NeoFlex section.

John I do this all the time and sometimes not by choice! I use a small round dish that allows me to suspend the print face in cleaning solution I will leave it over night some times to help break up the ink and keep it from drying out I call it my "lazy soaking." This helps for minor clogs but if your not clogged at all you should just need to give it a clean or two in the morning to get the cleaning solution out. I also do something similar when I have a bad clog like a channel missing, I will remove the print head and put it in my same dish, but I give it a quick flush first and use a small piece of tubing that I fill with cleaning solution over the bad channel and soak the whole thing over night, fill up my tube so the cleaning solution is sandwiching any clogged bits. Usually next morning it will flush nice and easy. I have saved so many heads this way.

Thanks James,

My issue is that I don't have the time to use or even clean my Neo each and every day just to keep the whites flowing - I'm NOT a fulltime printer

So I was looking for an option to the 8 hour programmed cleans;

1 to keep the whites from clogging in the head, and
2. to save on wasted ink.

Seems there's no definitive solution yet.

Regards

John
