Hey
Tipgypsy !
The tech who came here did exactly what Netsol said, when he removed the printhead, there was ink pouring from it and he said the printhead couln't be fixed. Later, I unmounted what I could and cleaned a bit more, it's pretty clean now, see photos. The problem is I should have done this immediately after the accident, before the system hault and 187 HDC SLEW RATE errors.
I found another Mimaki tech (third one) and I think I'll get the mainboard back and ask him to check it, still thinking. The dealer who sold the machine is not an option, because I moved and now they're more than 400 miles away. And also I don't trust them, because they charged me the price of 5 hours to prepare my machine to move, that washing procedure... but it was so fast and so simple that I felt stolen. They should have charged me by hours like they do with all clients and not the price of 5 hours for a 1 and half hour service.
Finding a good tech has been a challenge for me. There's just a few options around here and
can't trust anymore that Mimaki guy who said my cap didn't need to be replaced after 1 year and half. Also another day he was
removing the dampers with the machine powered on (stand by mode) and I was the one who told him it was better idea to unplug it because the machine could try to refresh at any moment.
Then, a second Mimaki tech who came months ago said
he wouldn't even touch the dampers because since one magenta line was missing already, removing the damper to check it
could break the head internally, which I'd found later to be untrue.
As you can see, I'm really trying to find a good tech, but I always end up here asking you for help, to avoid being scammed. And I thank you all.
