John_Admin,
I have done printhead cleaning, and ink charge several times. The position of the missing dots change, but still won't fully print.
I've had to replace a cartridge three times since I purchased your firmware. The first two times, I had to keep repeating this process 20-30 times. It finally started printing but this process used up about 1/2 of the ink. I've just had to replace a third cartridge and I've run the printhead cleaning and ink charge about 20-30 times and it's still not printing well. Dots are still missing and ink is being wasted. What can I try next?
