I have two problems that may be related:
I have the classical color staining problem (yellow, on a R2880, after first Piezography inks install and after following all the install procedure). I applied the capping station cleaning methodology but I was surprised by the sponge I found in the capping station: rather “hard”, not “soft” as I expected. It did not looked like a sponge, but more like fiber… I don’t know how to describe it: see the picture. Is that “normal”? I tried to clean but it was not very effective, and I didn’t insist.
I test the linearization (Selenium on Type5). See the picture of the curve: could it be related to the color staining problem, or is there an other problem?
Thanks for your advice!
