Hi and help
I ran completely out of ink on the LLK cartridge, it indicated that I still had ink in it. when I removed the cartridge checked it, it was completely empty.
I cleaned the printer as you folks specify. I have clanged all the boards on the cartridges because a few indicated there was ink in the cartridge and they were empty.
I ran the clean heads 5 to 6 times and the LLK does not get a drop of ink out.
I started to work on this a few weeks ago and had something come up that cause me to put it aside.
