Background. I have an Epson 2880 that I,recently, put in Cone (Inkjetmall) pigment inks. I was pretty sure I had all the color management issues done correctly so I felt I could print properly from Lightroom. I had made a few random prints and everything seemed to be OK. In preparation for printing, I decided to do a major cleaning. I used the Inkjetmall Piezoflush to clean out the capping station and then cleaned out each nozzle with the dummy cartridge (Inkjetmall). From Inkjetmall's videos, I thought I had done everything properly (moving the printhead and putting the paper towels underneath, etc.). I then refilled and reset all the cartridges and put them back in and turned everything back on and made a test print. What I got was a lot of black, messy, streaks on the paper. I did a bunch of nozzle checks and cleanings and, as I have been using a trial version of Qimage Ultimate, I tried their nozzle unclog feature. I had also used the Qimage shortly before all this but I doubt that Q would be the cause of any of this. Now, when I do a nozzle check, I get a controlled streak of colors across the top (bottom?) of the page. Slightly better but still a problem. From the videos, the one thing I did not do was clean off the wiper blade because the access seemed confusing I did not want to poke around and damage something.
Any suggestions as to what I did wrong or how I can fix this problem?
