Having done a print test before getting started, I noticed the Magenta had bled into the yellow side. Once I opened the printer and examined the damper, I could see it was 1/2 mixed (contaminated). It was a situation I would have to attempt myself as the tech guy is a 10 hr. round trip. So I thought to shoot some video of the process and upload it if I succeeded. Well, I did, so here is that video.
