3. If the problem persists, repeat the scan or copy using a higher resolution (High or Max if scanning,
Normal or Best if copying). You should also set background cleaning to 0, or set the content type to
Mixed.
4. If the problem persists, analyze pattern number 7 in modules A through E of the diagnostic plot. A
correct example is given below, followed by two incorrect examples. Note that there is a black ring near
the center of pattern 7. In this step, you must look at the region near the black ring. If you can see
discontinuities in the black and white lines, call HP support and report a “defocus or blurring” error.
