    developer units are known to fail on these models. could be a bad spot on guide rollers. scan in a pic, let us have a sample.

    Check that the "brass" connectors on the door are making proper contact with its opposite on the m/c, we've had m/c's where these have been deformed, causing "washed out" copies
