I wouldn't recommend, that is what the wiper should do.

I'd start with changing the cap top, as it sounds like you're in the process of doing. If you think there is a clog in the line you can try pushing some cleaning liquid from the line after the cap top to see if it goes through and comes out into the waste container. If it goes through no problem...

No, as that would mean you emptied out the cartridge. I typically pull a couple syringe full, depending on the size of the syringe. If you've done that and still no improvement, unfortunately, the head is not coming back.

Hi Kelly, by the syringe method, I mean that you connect a syringe to the line after the cap top before it goes into the t, before the pump and gently pull ink through, then do a medium cleaning and see if any improvement. If not, then the only real course of action is to replace.

Sounds like you might need new cap tops as well, especially if their older then 6 months. After the head soak would be a good time to replace if you have spares in stock.

I'd try a 48 hour head soak, turn off the power and unplug. Make sure you clamp off the lines after the cap tops and then use the tool to lower the capping station, mover the print carriage over a bit and fill the cap tops with cleaning liquid, move the print carriage back into place and raise...

Personally I'd keep it. They are work horses and easy to service yourself. Although parts are hard to get, 3rd party are easy enough, especially from sign-in-global. Newer machines I'd stir clear of 3rd party, but OEM are pretty impossible to get now for these and most of them work just as well...

Yes, you can do it yourself. Not really hard to do, if you're mechanically inclined. Just follow the steps in the service manual. *Edit: The only thing you can't do is enter the service mode, but you don't have to for a damper replacement. Just make sure to not leak ink, that will cause damage...

Welcome.

Could be a blockage. Have you made certain that there is ink the that damper?

Doesn't sound like cap top. Sounds more like ink isn't getting to the head either due to a blockage in the head or dampers or an air leak in the lines.

I would lean towards a head strike at some point. Can you do a nozzle test print, as well as take a look at the head from below and see if you can see any physical damage.

It could, but not guaranteed. It would be the cheaper option though, might be worth trying.

Understood. I haven't used a Mimaki, so wasn't sure if it had that other nozzle test in the service menu like it does on my Roland's. How old is that head and do you know how many hits it has on it. Maybe it is end of life, but from that nozzle test, it looks pretty good, so it's hard to believe...

Just to narrow things down a bit, have you tried printing blocks of each color (CMYK) and having it set to just print pure for each and seeing if one color has it opposed to all. I don't know if you can on Mimaki like you can on Roland, but can you print a service mode test print with the more...
