MK1 or MK2? Might be an ink valve leaking.

Yup, under the ink bottles behind the back panel is a series of valves. Have the service manual handy?

That’s not the ink valves caused this, the reasons could be: clogged air filter on magenta subtank, it’s inside the subtank and cannot be replaced separately, air solenoid assembly which controls pressure in the subtank or both.
I would start with subtank because it’s cheaper and consumable

Clogged bleeder filter on the dampers for me results in issues with filling with me, yeah, tied into the same system. The air solenoids, when bad tend to be clogged with ink (check clear lines leading to them for signs of ink getting into those lines). Or, when the seals go wonky, the air pump will run near constantly. But, on those notes, good to do a pressure check.
what is required to do a pressure check? the air pump does run a lot more than it should seems like

SubTank and/or +/- Pressure Air Valve. What are the readings on your positive and negative air pressures? What are the readings on the Mag SubTank?

If you have your install guide that came with the printer, that covers the routing. Should be under menu> #TEST > PRESSURE if I remember correctly.
so should I replace the magenta ink with new before running this test?

Pressure test should be fine without having to add ink.
Finally had time to get back to this.
This is the negative pressure
This is the positive pressure
Not sure if I'm checking them correctly?

If you have the installation/setup guide (Can download from Mimaki as well), it shows how to set the pressure on the printer. Usually done on installation, but those valves can creep out over time.
I checked the Mimaki website but all I could find was the Operation Manual and I didn't see anything about setting up the machine in there.
I actually found the hard copy that can with the printer, I'm going through it now
Where can I find the throttle valve that is mentioned in the installation guide?
I think I found it, the valve next to the coolant fill location
