Discussion SP540V help... air in Magenta line

[City Sign Princess]

Changed damper & cap top this afternoon and suctioned ink thru cap top tube only to get a bunch of air bubbles in magenta line see picture. Tube doesn't want to hold ink either
Anyone know how to fix this or any idea on what I am doing wrong?
I have changed dampers & cap tops many times before but never had this happen....
Thank you in advance for any help regarding my fix.

Cap top may not be sealing correctly.

any idea on how to get them to seal properly?

It is perfectly fine to have air bubbles in the cap top tube. Although the tube should be black not clear which means your cap top is probably aftermarket. We have had a lot of 3rd party cap tops not work properly for some reason so we always stick with OEM. If there is air above the damper then you might have an issue. But the cap top tube does not have to be solid for it to be working properly. In fact, you want it to drain out so it doesn't clog eventually.

Could be a bad cap top too if you're not using OEM. Can't remember if you can adjust height or not.
