I have a Taskalpha 552ci streaking magenta and cyan The copier has about 32000 copies on it and I replaced the magenta drum and cleaned the image area, which was not that dirty. I checked the transfer belt, did a developer refresh, laser lens clean, color registration, color calibration and auto gray adjustment. Any sugestions?

Streaking how, front to rear, lead to trail. Can you email me a copy or post a sample?
