Thanks for your reply. Actually, Richard was the one who responded to me earlier. He acknowledged the issues and indicated that he might try to work with Roy on a fix. I've been busy and check in only infrequently to see if there has been any progress.
BTW, my favorite profile was one Roy introduced for the 4900. It's called "Purge K" - only uses the PK or MK cartridge (basically, black only), and produces a very fascinating result, quite special to me, anyway :) However, it did not transfer over to the P800, even though the inks are similar, unlike with the 3880.
