Now circulation works time to time. I hear knocking sound of pumps. But problem with not turning off is same. We decide to change machine for next model. Hope that Mimaki fixed those problems.
No, it doesn't turned off. just machine don't do it! When printer is in sleep mode it makes circulation but didn't turn off after that! Same with FLUSHING and other cleaning cycles. Something is wrong with some sensor or mainboard or who knows! technician don't have any clue about that problem...
I flushed at least 600ml of cooling mixture and put new one. I am using Mimaki's antifreeze diluted with water 1:2. New problem just found today, because I am not main operator of the machine! Machine didn't make circulation over the day when we print! Before printer make circulation every 2-3...

We have troubles with magenta channel, all nozzles deflected and we need to change head :-( A lot of people have same problem!
