Thanks for bringing my attention to this point. I don't believe the print head could touch those left pads, unless a lot of "gunk" has build up.
I cleaned them anyway, which I don't think is mentionned in the maintenance video.
Removing the foam pads, cleaning them and putting them back was easy, but you should be carefull not to pull the thin felt pad underneath that I suppose drives the waste ink to a bigger pad, or you won't be able to put it back...
Maybe Dana could dis/confirm this and give a better advice, like simply putting some Piezoflush and soaking it up a few times.
Looking again at the video, my dirty wiper blade looks just the same, and I'm reassured my printer seems to work normally.
It's strange you mention the LC nozzles, I wasn't aware of a specific weakness here. It seems changing the cartridge solved my problem instantly, with the help of one cleaning cycles (I hate to do them too).
So printer or cartridge issue?
My guess is that all cartridges are made the same (same mold?) with different stickers and chips. Why would there be troubles with LC?
I have to add that Walker generously offered some compensation off forum.
Thank you all.
