Hello, Hope you or someone can reply quickly.... I too took my pumping unit out too and took the lines off one by one and flushed the lines out with a syringe and pressure. Got it all back together and now the ink won't pull thru the heads and capping station...I am thinking that when Brother installs these from fresh start up, do they put any fluid in the tubes to create a vacuum? I am thinking there is too much air in all those lines and it won't create a vacuum on its own...Any ideas or a test to make sure the pump is pulling air out of the lines? My heads are not dried up, they are spitting in the pad. And I run it almost every day in our shop.. I did a bunch of printing yesterday, when I noticed the magenta head print striped in testing..did a bunch of cleanings, and did not improve much, so I knew I had to clean the lines and I pulled out a bunch of dried ink in all of them... it was like heart surgery clearing clogged arteries. 6 hours, all lines cleaned and put back together...Any comments welcome..
