P8000 dumping ink on the floor

Hi, this is the first time I’ve posted anything here. If it’s in the wrong category or something - let me know.

Just wondering if anyone else has run into this issue:

I have two P8000 Surecolors.
They each have dumped a bunch of ink out of the back right side onto the floor.
One time, I’d estimate about a cup of ink.
It looks like black ink, but could be all inks mixed (on its way to the tank … ??)
It doesn’t appear to be a leak from a cartridge ( to appear black, it would have to be LK or LLK on the right side, and they seem fine - I think)

Before I start taking these things apart (they are off warranty) just thought I’d check if anyone here has run into this…

I’m sending LLK and LK and two carts asap.

sorry for this, sometimes this can happen.
