Hello All, I would like to know how many other people are having premature Print Head Pump Failures. I've gone thru 9 in a year & 4 months. Roland knows they are defective & plan to release a "New" style pump in June. But, when the pump goes, It will most likely clog the Printheads due to lack of suction. I've lost 3 heads now due to this. Any Others having the same problem? Please Post.
