Roland VS-540 - black head with over-spray and missing nozzles

We just moved a Roland VS-540, and the black nozzles are missing about 30-40% & about 20%
of the ones that are firing are deflecting.

I have cleaned the head manually a couple times, cleaned via the printer several time...
and have soaked the heads for half a day, no luck.

I'm going to soak them over night and see if that helps,
just wondering if anyone out there has had better luck with another method..
Thanks for any help.

 

You think? Here's pic of the Nozzle test:

Thanks all,
It was only unplugged for the trip to move it, about 4 hours.... as soon as I arrived, I put the ink cartridges in and turned it on.

I pulled ink using a 60cc syringe via the pump hose and crimped the other... no luck
Now I'm putting a cleaning cartridge in place of the the blacks and running a black box until
it turns clear-ish, & plan to let that sit over night...

Any other ideas?

 

Also... It was printing fine before the move, so that would rule out dampers, right?
