Most problems with image quality on this machine involve the Drum and Developer. If Drum has worn edge (yellow, not green OPC coating) on same side as your image problem, or if you remove drum and pull out developer and look at amount of toner on developer cylinder is light or has all of void lines on the side that your image defect is on, than start there. Good luck. Please post your results.
