My MB2720 recently stopped printing portions of pages; skipping several lines at a time. I have performed deep cleaning several times, but no joy. Note from the scan of the test pattern below that a portion of the black printing patter is missing both at the top of the pattern and at the bottom. The results may be seen in the document below
