Digital BW, The Print

Hello Arthur.

I have an Epson 4000 and have had something similar happen perhaps twice 
in total.  In my case I finally tracked it back to what I think was a 
progressively clogged ink damper.  I used an expended ink cart filled 
with flushing/cleaning fluid to first fill the line and magenta damper 
and then let it sit overnight and do a cleaning cycle followed by a 
number of solid magenta prints.

Another time there may have been some air in the line or a problem in 
passing enough ink through the damper to actually pull ink or cleaning 
fluid through the line so I very slightly overfilled the magenta cart 
(with cleaning fluid I think) with a bit of air from a syringe, which 
with a full cart should mean it was very slightly pressurized.  In my 
case this seemed to do the trick and normal printing picked up after 
clearing the cleaning fluid with a normally filled ink cart.

BTW, I now use only third party inks (Image Specialist/MIS), make my own 
profiles, etc.  and see no difference in performance or anything else 
with Epson inks except of course for the major price difference.
