Digital BW, The Print

I have been away from my 1400 Epson printer for some time and was not able to prep it for storage. There was a small amount of EB6 inks left and they have dried in the cartridges. Is there a way to save the cartridges, or are they cooked?

I have installed new cartridges with cleaning fluid and have run three head cleaning cycles. I'll let this sit for three days before trying new ink.

Any thoughts?

Thanks,
Gan
