Recently, my Pro 4000 printer has been leaving a black wet blob in the top right corner, which causes the print rollers to leave dots until it dries up. I suspect it might be the print head, but I replaced it only 18 months ago. However, I noticed that the little drain and squeegee in front of the print head was full the other day, and it took a lot of towels to soak it up. So, could be it the head leaking and not draining, or there might be some other issue?
