I'm using a 1400, by the way, and I know this group is for the 3800 series. But since your post popped up under "current threads", and was exactly the thread I was looking for, I came here. Hope that's ok.
I've been wondering too, which way was "right" when pushing down the capping station. So it's to your right as you stand in front of the printer. I was being very cautious about pressing it down just a bit without going to the right because it wasn't clear which way "right" was. Afterwards my station too was tilted just a bit, but I powered up the printer anyway... and it straightened out. So I guess I'm ok.
I'm also having trouble raising the wiper blade. I can't get my fingernail under it, but I was able to catch the edge of something that turned out not to be the wiper blade. It was a small white flexible rectangle (to the lower right of the wiper blade handle) and when I raised it a small projection came out of a hole. When I realized I was working on the wrong thing, I put the little rectangle back in its place. I hope I didn't do any damage.
Hard to explain all this in words!
PS: My very first post in the Inkjet Mall Tech Forum, btw. I like it!
