EFI H1625 Error 1273: Ink overflow?

on the EFI H1625, normally you won't facing the ink overflow issues even you shut down the power without close the valve, as that machine the negative pressure system was configured with a Big Air Tank in the bottom of the machine, which can stock some pressure for a period.
Once you are facing the ink overflow issues, it was suggested to reset the negative pressure system, and if the air tube polluted, better to replace it. to avoid next ink overflow happen.

 

Yet, how did you resolve the problem?

 

You would be better served to take the lure cap off the overflow tank (while the printer is off), and let it drain without a vacuum. This prevents drawing ink from the secondary through the vacuum lines.

it getting an overflow while sitting idle is concerning. There was a modification to this platform which eliminated that problem years ago, it was a new wiring harness and new multifunction board with a different sensor assembly
