siphoning wrong color

[DetailsGS]

Hi All,
I have a rockhopper 38.
I had lots of issues a while back with plugged nozzles and generally poor performance so i sucked some ink through the capping station. Then later during some more maintenance i sucked some through the waste lines to be sure they were clear.

The machine started perfoming much better and nozzle check is quite good now.

The problem is: Every time the machine parks itself it picks up a quantity of darker ink into the yellow line. I have to run some yellow to clear it out before every print. Even if its just parked for a minute or so. Also during a self clean. I assume that i have created some kind of unfavorable vacuum but any advice on a remedy would be appreciated.

Thanks, DK

Sounds like the pads on the capping station are swelled up cross contaminating the color side.

You can peel of the top layer of pad on the capping station or just replace the capping assembly and be done with it.

Good Luck!

You nailed it.
I had actually added another layer thinking that it should touch.
Once remove those symptoms stopped.

Thanks very much
