Digital BW, The Print

The story has a happy ending -I hope- (I'll let you know tomorrow :-)

I removed the CFS.
Replaced with OEM Epson carts.
Several cleaning cycles & nozzle checks and purge pattern printings 
with Epson carts.
Sucked about 100cc of ink through each chamber of the CFS.
Replaced the CFS.
Several cleaning cycles & nozzle checks and purge pattern printings 
with the replaced CFS.
A few test prints and all seems ok again. Sure hope it lasts !!
Thank you all for your help.
