VJ1204 Ink issue

Recently purchased a VJ1204. Pulled ink through the lines with syringes, but the ink seeps back up. I can remove the dampers and pull ink into them, but it does the same thing, goes back. Where else can I pull ink into? I try cleanings and nozzle checks and get absolutely nothing. I have purchased new dampers, cap top, cleaning solvent and wiper assembly. When I got it home, I followed the manual and installed ink cartridges, did a charge. Each color has two lines and where it splits into two lines there are black little caps. Could this be causing an issue.

 

Is there located where the cartridges go in?

 

I notice what sounds to be an air leak until I push this trigger down, then it stops. Is this normal?

 

I can’t confirm if the maintenance station is working correctly or not. I see where the double connector is, but how do I disconnect the lines to try and pull ink through? I am not against replacing the whole maintenance station, just figured I would try and see if small repairs would fix it. I appreciate your help!!

 

How do I pull the hoses out? I see where there are 4 lines that come together and are connected by white plastic piece and screws. Do I need to remove the white piece? Appreciate your help!

 

What is the third hole on the bottom of cap top for? There is also a third line that isn’t hooked up to anything except the little black box on the right of the other picture. Looks to be a nozzle of some sort.

 

No. I ordered a new maintenance station waiting for it to arrive. Hopefully that will do the trick. Tried head soak, pulling ink through the drain tubes and couldn’t. I don’t think the head was getting a good suction with the capping station. And then I pulled the clear drain tube out and really messed things up.

 

I received my maintenance station and put it on. Now I am getting error code E074err CR2 Current. At a total loss now. Any help?

 

I can move the head freely. It goes off the maintenance station fine, but when it tries to go back on is when the code pops up.

 

When I move the head back onto the station manually, it does go harder than it did with the previous MS.

 

It looks like there is a scratch and a small bit of ink on the strip. And the sensor gets right about there and then throws the code. Maybe is a coincidence that is happens right as the head tries to get completely on the station? Tried to attach a photo of scratch and ink.
