Need Help Damper change jv100 160

[Johnf]

Hi everyone
Has anyone got a video or instructions for damper change on jv100 160
I have got a little bit cyan mixing with yellow in test print and some magenta nozzles dropping out during print on print head 1

If you have mixing colors, could just be contamination on the wiper or possibly internal issues with the head. Not sure about a video, but dampers are just press-fit into the head. Just disconnect ink line, tug it out, then put in a new one and reconnect.
