Hey, Everyone. I have a T644 that is producing black copies. Text is visible but paper is black. Any suggestions? Thank You!

Bad power supply board. I do one a week. It is located under the transport bed. Loosen the four screws that hold the MP tray. With the cassette out you will see a hole sitting on a pin on the front and back of the black transport bed. Un snap those and work the bed down into the cassette area. The right side cover has to be off also to get at a single wire red connector.
