I could get the printer up and running with Epson colour cartridges combined with MIS blacks (my usual setup), by resetting the chips for the MIS cartridges. But I have not yet been able to get it to work with the cleaning cartridges (with freshly-reset chips).
I have a feeling that I am confused about something or I changed something and forgot what I had done. I have no idea what it is, though. I'll just let it go for a few days and it will probably be obvious. Sigh.
