Tekkie. Your the man.... i didn't take the cartridge out. But i noticed that last week. I've been having great test prints in the morning and all day. I thought the cap and pump swap fixed it. Maybe just took a while. But putting the pieces together. My magenta ran out and switched over to the next cartridge and that's when i started getting good test prints. How can i fix that? Or should i say how could my rep fix it. I'm still under warranty.
