He had another brand of the flush that came from the epson tech who changed the head .. I power cleaned the pink stuff though it, and have been running a cleaning cycles. I do not think we are dealing with clogs as it is a new head ... and absolutely nothing comes out. The ink lines are all moving ink and have gone from white to pink as your stuff replaced the old stuff .. and I could see pink in the drain tubed for the pump/capping station. Ive done regular and power clean ... fluid runs through during cleaning cycles but nothing prints.
I usually turn the printers off when they are idle ... I've never notice the pressure pump with my other 9800 when it is idle, only when I start a print or futz with the cart. So i have not noticed the pump coming on when this one is idle .. it seems to come on when I start it up or open an ink cartridge .. and again I pop a plug and there was pressure.
I just took things apart and looked for a fuse on the mother board ... the f6 fuse that would cut out the head seems a little diode a mystery beyond my skills .. and the only fuse there is - isa big fuse is insulated and looks fine ... so looked like nothing I could do there. The capping station is new ... and ink is going through is .. so I hate to pulpit for a new one (which I have). And I have not gone into the head and looked at dampers. I seem to remember when I changed dampers on my other machine nothing came out with a power clean... and I had to go back in and pull ink through, but since ink is moving through the lines on cleaning cycles I would think it is not an ink charging issue .. or capping station.
The manual says it could be three things ... The mother board, the print head ... or the capping station ... I am wondering if there is a diagnostic to distinguish which one it might be. It is a real clean machine .. and runs smoothly .. I would love to get it up and working. On the other hand If I know the gremlin .. and my other machine dies I can swap out ... the part.
