I operate our shop's Mimaki JFX200-2513 and have been doing the normal maintenance on it for the past 8 months. Recently in the past 2 months, I've been having issues with the negative pressure fluctuating between -1.43 and the normal pressure of -2.70. It doesn't go to numbers between, just those two points. The machine will give me a neg pres error message, I'll go to pressure adjust and it'll be stuck on the lower value for a while until it suddenly jumps up to -2.70. It seems totally random whenever it moves between the two. Because of this, I've had ink leakage pooling on both the heads and on the surface below it because there sometimes isn't enough neg pressure to hold in the ink. The situation has deteriorated to the point that a good hour or two of each working day is now dedicated to cleaning the pooled ink or trying to pressure adjust hoping that the Mimaki will fix itself long enough for me to do my orders.
I have been looking into this issue on my downtime. It's not the air filter on the side of the gantry since I've already switched it out for a new one which did nothing. I've installed a new Mp-e106684 Pressure Control Pump Assy which hasn't changed it either. From what I read, it might be an issue with the air solenoid valve, but I'd like to hear from more experienced folks before putting in the order.
